24p omission explained?
This source explains why there's no 24p at the moment. I'm trusting the information is legit, I personally lack the technical knowledge of HD video in the 5D2.
“The 5D MarkII will have 24p, it is already in a firmware running in testing. It was not released due to time but it was planned to be released with the manual control. This is not as easy as some people tend to believe. The codec data rate has 6 frames of spare bandwidth and the file size was still the same as the 30p in the cam I tested. They have to re-code the compression routine in order to run at full speed and not waste file size. This has introduced some problems in stability because the chip can only handle 30p natively and this is basically a hack. No Audio control planned or in the firmware as of yet.
The 60D will have 720p, 1080p video modes. 30p is already in the firmware and the Mark II hack could be used in this camera easily. Much better CMOS than the 500D improved even from the 5D Mark II.
Nikon is adding most of the same features soon in their cameras, Canon just wanted to release and get the claim of being first.”
cr

Any info on how long we might have to wait until its out of testing? I hope its not as much time as we had to wait for manual control.
Still, if they say they were planning on putting it in this release but couldn’t get to it, it might just be a matter of weeks.
On the other hand, it could be much longer as where they scraped the function as apparently they didn’t see it happen any time soon.
Ohh.. give us 25p please so people in Europe and Asia can finally film indoors under the lights again!
I don’t care much for video. But I want at least 12 stops of dynamic range at ISO 100 (same as Nikon D90) and better high ISO noise control!
we’re getting somewhere it seems! i hope this is true, sounds comprehensible at least.
Since when does the D90 have 12 stops dynamic range at ISO 100. According to the dpreview review it has 7.6 stops at ISO 100 and 9.7 stops absolute maximum.
i don t understand why 25 p is not even a matter of discussion!!!
here in europe we have as a standard 25p!!!!!!!!!!!!!!!!!!!!!!!!
we would also like to have the possibility to use the camera as the us customers!!!it s just a question of loyalty towards us european customer!!!!!!!!!!!!!!!
thanks for listening!!!!!!!!
So this source knows lots of insider info on both Canon and Nikon?
And what does better CMOS than 5d II mean? That sounds unlikely as it’s not going to be 24 mp and the full frame of the 5d II cmos helps it in it’s dynamic range.
For me the only real question is… WHEN ?
OF course, all these features will appear and the 60D will be released… but the real question is, how long will we have to wait.
I think it is something to consider for CanonRumors. Do not only look for info but also for timeframe and deadlines.
I don’t think “better” necessarily means “bigger”. With regards to video it probably means “faster”.
Yeah, why can’t this stupid rumor site give me all the reliable insider info I want?!! ;-)
Great info. Thank you CR!
I too have a question about better CMOS. How will the 60D improve over the 5DMKII?
OH NO NOT AGAIN,
WHENN ARE WE PLEASED????
WHENN ALL THE FRAME RATES ARE INSTALLED!!!!
IS IT REALLY SO MUCH ASKED IN THESE MODERN TIMES???
I guess it is not, or are they still needs to be confinced about marketing issues, that is are they still afraid off the new times?
I hope they will also program for the 25 fps Europe television commercials and movies!
And I don’t hope to start again making a petition to them.
They have had it enough you would think.
Ok lets see.
Onno Nugteren.com
I was referring to the results from DXOMark. The numbers do not really matter to me. All I want is clean output when I recover shadow details at ISO 100 or 200.
Better CMOS than 5D Mark II.
ISO 51200 and 102400, yeah yeah yeahs!!!
Will not even consider it unless I can get ISO 204800… :)
Come on, let’s be reasonable – better CMOS = thousands of 5D MkII owners using their 5D’s to crack the skulls of Canon Board of Directors members, so no way that the 60D is any cleaner at high ISO than the 5D MkII.
If we had a usable autofocus, then it could be used for wide aperture shallow depth of field for events where there is a lot of motion towards and away from the camera.
A person cannot manually adjust focus while running the camera without a rehersal and recording of the wanted focus settings like focus pullers do.
I think we will have it someday, but not for at least 2-3 years.
yup, I agree with Jordan, no way they will make better output images then the 5D Mark II, even the physical size of the sensor already kill the idea of it unless Canon suddenly improved the sensor of APS-C, den we have to wait for 5D Mark III to see it drop our eyeballs, if Canon manage to get the image output from APS-C better then a FF, imagine what will happen to a FF sensor? Im guessing if this truly happen, then we can expect the same technology in the next 1D/1Ds.
hmm, I don’t get it, before manual, everyone only want manual and 24 fps, now with manual, people now want 25 fps? Can’t we just get along the idea that a DSLR is not a video camera?
Probably less jello effect because it is faster.
If they can achieve the same high ISO performance as the 5D2, they’ll have accomplished their goal given the relative sizes of the sensors.
I am still waiting for the APS-C cameras to truly match the old 5D, even that would make a 60D a wonder of a machine! Well, I hope that in 80D or later this may come close…
For a person not so used to shooting video, I would welcome a much better AF during filming more than all kinds of frame rates…
they should try to get usable iq for iso 12800 first before going even further, don’t you agree?
3 years, that could be the 1d mk5 then. let’s hope we don’t have to wait for a usable af until then…
nice af in video mode, could it be an option for the 1d mk4?
Well in Europe our power supply runs at 50Hz which will cause a flicker with lighting with anything under or above 50hz but not multiple or divisive of 50hz…i.e. 25Hz/100Hz/200Hz or 25fps/100fps/200fps etc.
Hence…we need 25fps to get the non flicker quality like 60Hz countries….:)
As a Canon developer I can now (finally) speak a littlebit, but I have to dissapoint you as this post/rumour holds no ground, except for the fact that the chip runs on 30P.
I am sorry for you all, and hope I don’t upset you.
But this is more honest then believing the rumour sent out by CR now.
Wow. Just wow.
I don’t believe you are a “Canon Software Developer” because employees there dont slag off rumour sites and stays quiet. Were is your employment staff number with Canon? I thought so…..a Nikon fanboy with a jealous grudge more like.
Canon spoekswoman said a few months ago engineers are working on 24p.
Here I am not talking about CanonRumors responsability, but about Canon responsability (and all the “sources” from CanonRumors).
Let’s make things clear. Even if the 50d was released just 9 months ago, it is already completely out dated compared to concurrent, and more problematically, compared to the other Canon cameras.
First, many pointed that, on the photographic point of view, it is not better (or even worst) than the 40D.
Second, from the features point of view, the absence of the video mode is simply ridiculous compared to Canon T1i or to the nikon concurrents.
So now, the question is simple: when will canon have an “expert” camera which simply fits the concurrent and makes sense relatively to their other products.
SO @gwac: You can be ironic, I just try to be logical.
Oh I just have to hope that the manual exposure control comes to the 500D/t1i…
+1
Yes, AF is the area I hope they emphasize for the 60D.
[CR1]
The CMOS chip senses the light. It has nothing to do with the speed. the jello affect comes from the rolling shutter that is inherent to SLRs
No. It’s obviously not possible with current lenses.
umm not likely.
not for stills, at least.
How do they suddenly make up for a 2.5x larger light collecting area?
OTOH, for video, you are basically talking about performance of photosites, since 1080p is 2MP whatever sensor size they capture it on and they don’t yet seem to have enough speed to bin, it would be amazing enough if they were even able to make the 60D less noisy per pixel than the 5DMkII, but perhaps possible.
But maybe they just meant it will have less jello or maybe they will have enough power to read off the sensor faster and bin pixels together which could make for less artifacts and less noise than 5dmkii video?
wow, even the phase focus gets complaints for sports tracking and you think in just three years they will have contrast based tracking good enough for f/2.8 serious level sports shooting? They will be lucky to have it good enough for basic scenes of modest action IMO. Hollywood with all the money still uses people to focus when they shoot.
What you are talking about, unless they use some sort of split mirrors etc and use phase AF with video I think might be more like 5DMkVI than 5DMkIII.
I Would Love Too See What Can 60D Give Us…
Can some one tell me why I want 24p? I do shoot video with my MKII, but it’s really spur of the moment stuff. I bought it for photography, but was very pleasently surprised by the video. So, why will I benefit from the 24p, and for that matter, control over the video shutter speed? How does the shutter speed diferentiate from the frame rate? (I’ve assumed that you folks want manual control of the shutter for exposure adjustments, I just can’t seem to see how that seperates from frame rate). I know my camera inside and out with respect to photography, so teach me something about the video! Enlighten me!
My understanding is that the “rolling shutter” is due to the nature of CMOS output, which collects output line-by-line, as opposed to at a single point in time. It seems to me that if you accomplish this readout faster, the “jello effect” is reduced if not eliminated. But you obviously know a lot about this so I must be mistaken.
It runs at 30 lines progressive?
Please explain.
No offense was intended. I do think it’s funny, though, that people take their frustrations with Canon out on this rumors site. It’s just for fun!
25fps is more useful in Europe. As mentioned, the lights flicker unless you have some even division of 50Hz. I also believe the 24fps is more of a film standard, and corresponds to the film motion picture industry standard. No re-encoding necessary, 1 frame = 1 frame.
Shutter speed: There are two measurable gaps between shots. The time between the middle of the exposure, and the length of the exposure.
Frame 1, 1/125th
close, wait 1/125th
Frame 2, 1/125th
close, wait 1/125th
…
Frame 1, 1/30th
close, wait 1/220th
Frame 2, 1/30th
close, wait 1/220th
Something like that.
You can maintain a frame rate while the shutter speed varies.
24p with a 180 degree shutter is what’s used in film.
25p with a 360 degree shutter is what’s used in video in europe.
Obviously you wouldnt be happy with your canon having just the green square retard mode so we’re not happy getting a green square retard mode in video.
The manual control that are coming are awesome but for people that still want to capture footage that looks like film and not some junk video just because of a few framerates we’re still asking for 24p.
Then again, every known filmographer that ever touched this camera is asking for the same thing now.
If you want to learn more about how the shutter speed is related to the framerate I suggest checking out some free videos over at digital juice DJTV – one specifically explains this with examples on water and golf swings.
Thanks for reference. I totaly get the desire for manual control, I primarily shoot in manual or Av, so I can understand, respect, and support that need. The green box blows except when I hand my 5 yo a camera!
So basically, you want 24p because that’s the standard in the film industry? You did not mention why it’s beneficial over 30p, etc.
So the 30/24/25 frames per second is fixed, but the exposure during a given frame varies, and is defined by shutter speed.
Yes. It is fixed at 30fps no matter what. The shutter speed can vary from 1/30 or anything faster up to 1/4000 (or at least that’s what will be available when the new firmware hits – don’t know what the fastest shutter speed currently is as it is all automatic so I don’t know that it’s possible to tell).
People want to be able to choose the frame rate be it 24, 25, 30 or whatever based on their creative wishes or due to technical issues (50hz power in Europe and Australia for example).
If you look closely at how the film “looks” and how your footage “looks” you’ll notice several things.
The biggest is that the movemet looks film-like in film, but looks cheap-soeap-opera-crap-like in 30p (60i).
It’s because we’re used to seeing quality film footage shot at 24p with a 180 degree shutter. And we’re used to seein crap live TV video footage at 30p with 360 degree shutters.
Try transcoding your footage or check out some vimeo results for “5d 24p” and you’ll see what I’m talking about.
There is no technical reason why one would prefer 24 over 30. It is a creative demand. For whatever reason, the film industry adopted 24 fps years ago and people like it. Filmmakers want their films to look like films have for decades, they don’t want them to look like daytime television which is what you get with 30 fps.
People would find it odd if their TV show were shown in 24p and likewise they’d find it odd if their films were in 30p. One is not ‘better’ than the other, they are just different and have traditionally been used in different ways.
The 25 fps, while close to 24 fps, will look like cinema, though people in Europe and like places have mains power that operates at 50hz which makes their lights appear to flickr when filmed at 30 fps. They want 25 fps so their lights will be in phase with the capture rate of the camera.
Thanks for the answers!
With the slow economy and Canon’s sales/profits in the tank I would not expect the 60D any time soon.
It’s not just the lenses that are preventing AF in video recording. The AF system in DSLR’s were designed to have the mirror flip up after AF is achieved to expose the sensor to the light – for video recording the mirrors stay up, so the normal AF mechanism is not live.
The AF in the video line, such as the HF S10, is quite good. Once they incorporate that into the DSLR’s there should be some very good AF in video modes. Not sure you can ever use the phase AF in video mode because the mirror is locked up so no light hits the AF sensor.
All the NTSC video cameras record 30p/60i only. The “24P” modes they offer on camcorders are pulldowns from 30p such as 2:3:3:2 or 3:2 pulldown schemes.
30p can be preferable over 24p since performing a standards conversion to 25i PAL has fewer technical complexities – any NTSC-PAL converter will do. The larger differences between the 30p and 25i framerates will cause less noticeable motion artifacts upon conversion. If the camera was native 24p it becomes problematic to make it 25. So they make the cameras in 30p and use pulldowns to make them 25p or 24p.
As a quick historical note, 24 fps was the fewest amount of frames you could use to see smooth motion. When producers wanted to try to buy the least amount of film possible, this was key.
30 fps was chosen in television (29.97 to be precise to sync up with the FM sound carrier in the signal, another long story) in NTSC due to our 60 hertz rate here in the states. Interlacing actually paints the screen 60 times a second, but only every other line, which means you see 30 frames a second. It’s a little weird, but nobody was paying for film (1950) and NTSC was convinced televisions added six frames would make it look smoother.
But overseas, they use 50 hertz, which means they’re seeing 25 fps. Hence, all the stress from our English and European friends who want to simply use the video option on their cameras as advertised.
The main point of everyone is that if Canon can make the camera do 25 fps, it’s just a quick stop to 24 fps to achieve matchie-matchie to film standards, which would eliminate re-rendering later on in post-production. You’ll hear the same arguments from those that want Canon to sync down to 29.97 fps to avoid more rendering to match actual television standards. This is a good link to explain:
http://www.andrewduncan.ws/Timecodes/Timecodes.html
What would be absolutely rocking is somekind of .CR2 video format. :) Like the RED has .R3D.
.
“Much better CMOS than the 500D improved even from the 5D Mark II.”
– In what aspects? what specs would make it better than the one on the 5D Mk II ??
All well explained above.
And an additional note: PAL is also the standard in South America, so the whole market using PAL is bigger than NTSC indeed.
I can see a point using an old CRT TV or maybe cine projector. How is this relevant to MODERN TFT LCD devices that have refresh rate at 60Hz or far more?
It sure wasn’t the 20 fps on the 500D…
I’m skeptical about this whole matching light frequency idea of 50 hertz vs. 60 hertz making 25p or 30p such a big deal. You’d think sunlight which is neither 50 or 60 hertz would screw that all up and yet the cameras can shoot just fine in sunlight. And I’ve never noticed any flicker shooting video in Europe indoors vs the USA. Maybe if you’re shooting the TV screen itself it would be a problem if they dont match. Other than that I think the posters making a big deal over that idea are mistaken or tricking people.
In any case, the issue is a lot like a photo, if you blow it up (ie 25p to 30p) it’s gonna suck. It’s always easier and better to downsample (30p to 25p or 24p) – and this is exactly what the manufactures do via pulldowns with the cameras recording at 30p native. So all this whining about no 25p or 24p is just silly.
Sunlight is essentially constant to our eyes and cameras so of course it doesn’t cause problems for video cameras of any type. Your argument is flawed.
Correct me if I’m wrong but the pulldown in TVs and DVD players is to display native 24p content to display on a 30p/60i display. Until recently televisions were unable to display 24p content without conversion but many TVs now refresh at 120hz or more and 24p is easily divided into 120 which just means that each frame is shown for 5 cycles, no conversion necessary. It has nothing to do with the recording, converting or editing of video but is only pertinnt to playback so again I think your argument is flawed.
For interest sake, I looked up the bigest 85 countries & what TV system they used.
PAL = 64%
NTSC = 17%
SECAM = 19%
So those on 30Hz (NTSC) are in the minority.
PAL & SECAM countries use 50Hz.
If Nikonrumors is correct, D300s will launched soon. It is nothing more than D300 + movie function. We’ll see if Canon can FINALLY match Nikon’s D300 after all these YEARS. ;)
I guess the reason why they added this functionality to the 5D Mk II is due to the release of the Canon 60D soon.
The next 60D will most likely have the video specs the 5D MK II have currently before the update and this will be the method of differentiating both of them (besides the sensor).
The important thing will be whether somebody will be able to hack the current patch to the Mk II for the 60D.
Sunlight must have a hertz frequency too. So it seems to me it can’t both accomodate 50 and 60 hertz according to that theory they are inherently incompatible due to flicker concerns.
And you are partially wrong about pulldown, yes it can go from 24p to 30p 3:2 pulldown it can also go the other way 2:3 or 2:3:3:2.
Also, I’ve shot video in Europe and USA indoors and never saw this supposed flicker issue from light on my NTSC camcorders. If you are shooting a TV screen then sure I can see that as an issue, but not from the light bulbs.
yeah, but it still doesn’t touch phase contrast AF. Again, even the fastest phase systems can just barely keep up with high level sports photography
and the HF S10 has more DOF deosn’t it, that helps mask things compared to shooting a 400 2.8 at 2.8
yeah, i was thinking some sort of pellicle mirror or other trick with partial mirror and AF sensor in a different location than usual, but who knows when/if that ever happens
the sun is not a fluorescent bulb running on AC!
it’s a fusion furnace that pumps out photons at a random and ridiculously high rate. The earth is bombarded by a constant stream of photons.
actually lots of TV shows are shot at 24fps
almost all the dramas Lost, Terminator: The Sarah Connor Chronicles, each of the ten million different versions of CSI, Veronica Mars, Scrubs, and so on. Some of the older dramas appear to have been edited onto videotape or something though and only still exist in a lo-res worn out videotape format anymore.
And not just that, most TV shows, 30 Rock and many comedies also look to be shot on film at 24fps.
Nightly news looks to be video and most, if not all, reality stuff also looks like 60i video. Sports looks mostly like 60i ot 60p video. Probably most talk shows and many soaps too.
Wow it’s not flourescent?
oye
If Nikonrumors is right, we’ll soon have a D700s which is nothing more than D700 + video capabilities. Canon has a few years to demonstrate if they have FINALLY caught up with their competition.
That would be incorrect, except for the pro sports bit which is indeed mostly 60p now, not 60i which is the same amount of lines as 30p.
But all those shows are shot on video not film.
It doesn’t matter. They are still using a pulldown from 60i or 30p to get 50i or 25p.
Even if they have the exact same video features the two cameras are different on many other levels and are in no danger of being the same.
I think you are mistaken. What you’re describing is true of shooting TV screens perhaps but not lighting.
It doesn’t matter, that’s why. The only place it matters is on blogs full of misinformation that are getting people all worried about 30p vs 25p.
Maybe a pellicle mirror would work. Problem is these DSLR’s were not origially designed for Liveview focusing as all the R&D went into improving phase contrast AF back in the film days long before anyone thought they would ever record video. Now that they realized these cameras can record video too they are having to rethink and redesign for that, and Liveview is still pretty lame being that was also an enabled LCD screen feature that was not originally designed for focusing the camera.
As for the HF S10 and a 400 2.8 I have no idea how well it would work but I’m sure it would be far better than what the DSLR’s can do at this point with video focusing.
I’m shure that Canon will enable 24, 25 and 30p and maybe also a 720p mode shortly.
There is a lot of unused power in the 5D Mark II so I think we can expect a few more intresting firmware upgrades. I’m shure they are working on some inprovements also for the camera function.
I don’t Canon have any plans to replace the 5D MK II before 2011.
I think the real question for those of us shooting video is when will we see Canon upgrade the XL line of Camcorders to solid state media. Panasonic, Sony, and soon JVC are running the show with this. It seems sad to get great 1080p video out of a DSLR while the XLH1s is 1080i on DV tape, while they are at it they should ditch the 1/3 sensor for the now becoming standard 2/3. I have just recently shot a ton of video for work with the 5DMKii and I am really really really pleased. In a studio or on location with controlled lighting the quality is great. I am looking forward to the firmware upgrade for a little more creative control with Canon lenses.
that is actually not true. in practice the 24fps->25fps conversion consists of just playing the movies a bit faster (seriously) that is why film to PAL is so easy, and Film to NTSC is a major pain.
whoops thats what i meant cmos slr’s
And still… the description of “better” cmos is vague and seems more like guess that reality.
Only way to get rid of the wobble is to have a global shutter function with the cmos instead of the rolling one
http://www.reduser.net/forum/showpost.php?p=35514&postcount=159
Here is a good post explaining why it’s probably not going to global anytime soon.
Incandescent light has a lot of inertia, so there is no problem. Perhaps there could be problems with fluorescent. In this case the best thing is to change the ballasts with electronic ones.
Simon
How about “no”?
Most of those shows are shot on film.
And the “look” of film comes primarily from the 180 shutter angle and ratio of shutter speed to frame rate.
No, we don’t – we do use video and film cameras that shoot at native 50i and 25p without any pulldown like you describe. And yes, 30 and 24 fps cameras are a headache on location shooting in 50Hz countries due to light flicker. So the lack of a 25p version is a big reason why I haven’t bought a 5DmkII.
Flicker can still be seen with incandescent lighting shot at 30fps. High Frequency Ballasts can stop the flicker with florescent lighting but could be very costly and time consuming.
Flicker is still very much evident with TV screen when shot at 30 fps or 24 fps.
Yeah they speed it from 24 to 25 because a pulldown from adding frames is problematic! What I wrote is true. I’ve worked with converting film to video and the whole PAL/NTSC issue from several Bollywood projects in India I worked on.
Not one of those shows is shot on film.
I’ve been on the sets of several of those shows and I know one of the post production companies that contracts with the production studios and you are completely mistaken. There is no time in TV production for film editing and conversion problems that could easily result in missing a delivery deadline. The “film look” is all done in post along with the rest of the effects/CGI.
I think that is a fanboi myth being propogated by people who have never really had the problem. Bad flourescents will show flicker on ANY video camera because that is what bad flourescents do – you can see the flicker with your own eyes so you know it’s gonna show up on the video too, and if you are shooting a TV screen you have to sync the shutter speed to match the frequency on the TV, other than that this is much ado about nothing except fanboi whining.
I’ve done numerous shoots in Europe, South Pacific, India and such PAL countries with NTSC and PAL cameras, and I’ve done post and conversion work from cameras shot in PAL in the USA and the reverse – never seen this flicker issue or even heard of it until I started reading all the whining on this rumor site about the lack of 25p on the 5D2.
“if you are shooting a TV screen you have to sync the shutter speed to match the frequency on the TV”
OK, my TV uses PAL and a 50Hz power supply. PAL is interlaced, so I get 50 fields per second and 25 frames per second. What shutter speed would you recommend?
Economics. The market is too soft. They dont want to start up production on new models when the camera aren’t going to sell enough.
I used to know the shutter speed for that, but i’ve not had a need for it in many years, and I dont know if the LCD’s are any different than the tube TV’s in that regard.
I’m still confused about the “flickering” problem with 25p that people keep bringing up, and I’m wondering if someone can point me to a sample video where this is apparent – I’ve tried to find examples on the ‘Net, and can’t find any example…
I can understand why people would want native 25p to avoid the conversion process if they want to create a PAL or SECAM version of the video, but the “flickering lights” problem just doesn’t make any sense to me. If you’re filming using tungsten lights, or outdoors in the sun, there won’t be any flicker at all – both are a continuous, flicker-free light source. On the other hand, if you’re shooting an old CRT or under cheap fluorescent lights, then sure, there’s a problem – but why would you choose to use either as a for lighting a scene? The light would be terrible even if there were no flickering…
Again, I can understand why people would want to choose 25p to avoid conversion in post, but I don’t believe that the “flickering” problem is a real problem. That said, if anyone can point me to a video or two that shows that this is a legitimate problem, I’d be more than happy to change my position…
Of course, there is an aesthetic argument to using 24/25p over 30p – I completely understand that (although I believe it can be achieved in post-production, but I can see for people who don’t have the equipment to convert in post would like it native in the camera). I’m really just saying that I don’t believe the “without native 25p, video is useless to more than half the world because of flickering light” argument has any merit.
Anyway, I wouldn’t have bothered to write this comment, but I keep seeing the same argument again and again, and I think it’s incorrect.
Sorry for the rant… :-)

You “think it’s incorrect?” In ten minutes of web surfing you could figure out that “you’re incorrect.” This is an old, well-known, well-documented issue. What do you think, people are just making this up for the hell of it?

I have been at the big sun frequency transformation facility. They actually perform a conversion from suns native 99.97 Hz to 150 Hz. You should have seen the magnets! Now why they prefer 150Hz is completely beyond me. I asked but they uttered something about ‘IMAX … future … PR … contract’ so who knows. I take it as a sign that IMAX will go up to 150 fps. wow just wow.
(note to us Europeans: they are working on a switch for european daylight time: 25Hz – just for us, now that’s what I call customer relationship management)
That was brilliant, jack
It is inccorect. The problem is the lack of manual control over the shutter speed, which if you set it to 50 or 100 would solve the lighting flicker at 50 hertz. You can get the same problem with 30p in 60 hertz lighting if your shutter is not set in sync to it. The 5D2 picks the shutter speed for you so you can’t control it – that is the valid problem.

Well said Peter T. Spot on.
Well yeah true lots of sports is shot at 60p. I should have put that in. ABC Sports, ESPN, etc. but CBS and NBC still do 60i.
As for none of those shows are shot on film I’m sorry to say but you simply have no idea what you are talking about.
As for the I know so and so and have been to the sets and so on, if actually true, then either you didn’t recognize what was being used or misunderstood something they told you or happened upon a set where perhaps for the most recent season or two they did end up switching to 24p HD Video Cam shooting (there were some rumors during S2 that Lost would switch to digital 24p shooting starting with season 3 or 4 but i’m not sure if they ever did or not).
Anyway, at the very least, that stuff was certainly shot on film to start with and I believe much to all of it was at the end, as well, although perhaps a show or two switched to 24p hidcam of some sort or other for the most recent season or two.
here are a few quick bits going along with what I said:
http://www.imdb.com/title/tt0411008/technical
says Lost was shot 35mm 3-perf
doesn’t appear to mention any later switch to digital (but maybe they didn’t update it)
oh and what have I googled up here from Kodak:
https://www.kodak.com/US/plugins/acrobat/en/motion/hd/truth_film_hd.pdf
granted that last post doesn’t cover the most recent seasons (for the shows mentioned that had further seasons) but just to check against the list I gave above that you said I was 100% wrong about, well let’s see was it shot on film?:
Lost – check
Veronica Mars – check
Scrubs – check
CSI – check
Sarah Connor – show was not out yet when kodak made that flyer
So where was I wrong exactly?
And let’s just add to the list of TV shot on film:
The OC,Charmed,7th Heaven,One Tree Hill,Smallville,24,House,Desperate Housewives,Everybody Loves Raymond, and this is tiresome I could probably type 60 more lines of shows.
“oye” doesn’t exactly provide evidence of much.
there is no problem having anything to do with handling both 50 and 60Hz from the sun, it doens’t make any sense.
also, downsampling 30p to 24p is not easier, they shoot at 24 because it makes it easy to do everything from theater display to 3:2 pulldown for TV sets that don’t allow native 24p to european 2:2 with a tiny push for sets there that aren’t running at 24Hz.
oops, i had mentioned sports at 60p originally too.
it’s a click of a button to downsample 30p to 24p
and what about non-NTSC video cams, they do a real 24p.
and if 30p makes it easier to transfer worldlide then why does everyone in hollywood say the opposite?
I’ve been on the sets of Enterprise, Stargate and Galactica and they were shooting digital. It’s amazing they can hit TV production schedules shooting film, I still find it hard to believe.
a click of a button is easy for you to press but it results in either dropping ever 5th frame or the computer to sit there struggling to do all sorts of complex things which it might not do perfectly well.
I’m surprised no one has commented on the statements about audio. It can’t be that hard to address this issue; a hacker is in the process of doing it independently. Being able to turn off the AGC is a big deal. The 5D2 is capable of high quality audio if the AGC can be disabled.
well, probably in another few years it will start becoming quite rare to shoot film any TV on film, but I think they will still shoot 24fps native in digital though and not 30p or 60p, at least for quite the foreseeable future (and as I said, perhaps Lost has already switched over this past season to 24p videocams, not sure).
apparently there are a few comedies that switched over to 24p digital already from film relatively recently.
I haven’t ever heard anything about the production of the three shows you mention but everything else that has used digital to shoot that I know has used special native 24fps digital cameras so I’d be surprised if they were actually using 30p cams. The ones you mention do have tons of effects and a couple, at least, I believe are also on are slightly lower budget (as opposed to typical cost on say CBS/NBC/ABC/FOX) shooting network SciFi so they might have found it best to go to digital cams ASAP.
Off-topic, but speaking of scifi, let’s hope they pickup Term: The SCC. FOX buried that against MNF and then Friday night and they also had two hiatus and so on and didn’t seem to give it the best of shots.
Just to be clear I never said they weren’t shooting 24p.
I prefer 24p myself but I find I can easily get that in post, which I do specifically because 24p video is not ideal for action/motion, so I get the clean footage in 30p and post it to 24p for the look I want unless I’m sure recording 24p will be fine.
Also, they may be still shooting a lot of TV shows you listed on film, but the post is all HD, which is where I run into it at times and assumed they were mastered on HD.
Californication is shot on HDCAM and they use a bit of 16mm that was shot with a Bolex for transitions/effect and on the title.
I’m familiar with ARRI and other film cameras, and I’m certain there were no film cameras on the sci fi sets I was on.
Probably because many of the filmmakers shooting with the 5D2 use separate audio recording – I do on many shoots even with pro camcorders that have good XLR inputs. At this point the 5D2 is not a great camera for casual/candid on camera mic type of shooting anyway.

pellicle mirror is also gateway to AF at high framerates for stills
Guess I’ve been imagining all the strobe flicker I’ve seen since the 80s then when using 24 or 29.97 cameras on location here in Stockholm, Sweden so I must have been a fanboi (of what I wonder) since then…
Quite the contrary, it’s a 5DmkII fanboi myth that it _doesn’t_ happen. Given you seem to have pulled that strange pulldown ‘fact’ regarding how PAL video cameras work out from somewhere behind I guess you are one.
And with all respect for your wide experience shooting around the world I’ve actually tested the 5DmkII in 50Hz lighting here and it’s a roughly 40/60 toss up if it occurs or not unless the shutter is forced below 1/50 (hard to tell as the cam don’t report the correct speed at all times in video mode) yielding a overly smeary motion blur. And by flicker I don’t mean a old/bad-flourescent-visible-to-the-eye-flicker but a interference or strobe pumping of light intensity, under both flourescents and street lights.
For me 5DmkII is currently not a reliable tool for work. Try before buy in 50Hz countries is my recommendation, until Canon manages to release a 25p version. You do know we with 50Hz electric power and PAL/SECAM system are in a vast majority in the world? So from a market standpoint it would be a clever decision by Canon.
changing the shutterspeed might make it less visible, but shutter speed has nothing to do with synchronization: if you set the shutter speed to 100 you would still get 30 fps = 30Hz, thus each at a different moment of the 50Hz power-cycle in PAL countries -> flicker especially with flourescent light sources.
So it is correct.
Well, the next 60D featuring the video specs of a 5DMkII before update…then the 70D maybe will feature it ;-) Anyway, I won’t buy an upgraded body for video purposes. I am in photography and that’s it.
Guess I’ve been imagining the light flicker at times with my NTSC XLH1 here in the states at certain shutter speeds…
It happens in both 50Hz and 60Hz with the 5D2 depending on the lights used and whatever shutter speed the camera decides upon.
I’ve shot the 5D2 for testing and I will not buy one at this point. The GH1 Panny with no mirror to get in the way might be a better choice for HD quazi-SLR shooting until someone figures out decent Liveview focusing on SLR’s and manual control.
yeah, all the post is on HD
My local TV is PAL standard, but I’d rather the Canon 5D Mk 2 have it in 30P than 24P or 25P if I can only choose one. Technically speaking, the quality will be better if I were to convert 30P to 24 or 25P than the other way around. But obviously, all 3 will be great!
you are right the real problem i the rendering, it takes ages and the result is not good!
i have tested it several times and was very disappointed!
i hope 25 will be a reality soon also with the 5D!!
As the cliche goes, a little knowledge is a dangerous thing.
25p is important for PAL countries with 50Hz power.
Discharge lighting like fluorescent, HMI, sodium vapour, mercury vapour etc. can all flicker very badly.
In a studio situation it isn’t a problem as you can use flicker free ballasts and the like.
However for location shooting where there may be street lights or domestic fluorescent lighting etc. or if you are using practical lights in-shot it can be a show stopper.
Constant lighting like tungsten lights with a filament or DC powered lighting like carbon arcs or Lightning Strikes SoftSuns etc. do not flicker at normal shooting speeds. When shooting at high speeds, any AC powered lighting can flicker, even tungsten.
For example in countries with 50 Hz power, when you are shooting with a film camera at 24 fps, you use a 172.8 degree shutter, to get an exposure time of 1/50 th of a second.
If it wasn’t important. Then film cameras wouldn’t have a shutter setting of 172.8 degrees.
25p is also very important in PAL countries to make a standard definition version of your product. It is very difficult to convert 30p to 25p and get a nice, smooth result.
It’s important to have a standard definition version of your product because there are few domestic HD distribution formats. Bluray is about the only popular one and it isn’t that popular. Supplying HD for Broadcast is no problem obviously, as there is a dearth of good HD formats.
Previously many of the big episodic shows in the States were shot on film, however most of the shows are now shooting digital with either Panavision Genesis, Sony F35 or Sony F23 cameras. This season in particular there was a huge exodus to digital in LA.
24P is important because it looks very different to 30p.
If you don’t understand or don’t agree, you should study this more as it is one of the rudiments of digital image-making.
please canon give us 25p or i will be forced to sell the 5D for something else not as exciting!!!!

I can’t believe all these arguments! I’m a cameraman working in the uk, but I have shot in both ntsc(60hz) and pal(50hz) countries. It doesn’t matter if you are shooting film or video if you shoot at 25p in a ntsc(60hz) country you will very likely get flicker problems with lights, whether they are tungsten or florescent. This is because the refresh rate of the power supply is different from refresh rate of the camera. This is also true of shooting 30p in a pal(50hz) country for exactly the same reasons. Sometimes the flicker effect is subtle, sometimes not but it is 100% real! Sometimes you will hardly notice it on a small screen, but it will be very irritating on a big screen at the cinema! Of course, shooting exteriors lit by the sun will have no flicker problems whatever you do.
24p, 25p and 30p have slightly different looks but the difference is subtle, the main difference between the tv look and the cinema look is that is that traditionally tv (soaps, news, entertainment programs, cheap drama) has been shot interlace (50i or 60i) where as film and better quality video has been shot non-interlaced. In the case of film this has been 24 or 25 frames a second, or video 24p, 25p or 30p – meaning progressively scanned.
There is nothing inherently wrong with 30p, played backed it will still have that progressive or cinematic look but technically it will cause problems in europe and south america, both when shooting and in broadcast.
It is true that the flicker effect can sometimes be negated by careful use of the shutter, but this is not always possible and I personally want to use the shutter as creative tool not be forced to use it at a dictated setting just to stop flicker.
This camera needs 25p, not because of cinematic look or any of the many spurious reasons spread around the net, but because in a pal(50hz) country this is technically what it needs to be, and all other pal video cameras whether professional or consumer are.
What is the meaning of “…This has introduced some problems in stability because the chip can only handle 30p natively and this is basically a hack. ”
The chip can only handle 30p natively. Which chip?
The DIGIC 4? The CMOS?
If it is the CMOS, is it possible to get 24 or 25 fps without tricks like the ones that we do in post, I mean get pure and exact 24 or 25 fps.

the 50Hz issues exposed and solved :
flicker free shooting with the new firmware
http://www.vimeo.com/4991966
no 25fps = no buy. new nikon is coming and you will get 25fps mode with it so i would wait for that.
everything edited for pal countries is edited in 25fps so professionaly we want a camera that does that- simple. 30p is ok for filming the kids etc or web based…but 30p to 25p conversion is too problematic at moment.
I like to watch Veronica Mars episodes as well Lost. I found your blog on google and read a few of your other posts. I just added you to my Google News Reader. Keep up the good work. Look forward to reading more from you in the future.
I’m new here with canon or any other cameras, so I want an answer about is that ok if I make a movie with 25 Hz film and use it in analyzing program as a 50 Hz film.
Is that ok the concept that we can divide the film was taken with 25f camera to be 50f.
I made numerous shots with the 5D2 in germany but with the manual control available now. The flicker problem is no problem. Shutter set to 1/50 and I never run into flicker problems. It could record 45fps, and there would not be a problem ;-)
Peter T. is absolute correct: It is a PITA to do the post process with that 30p stuff to do a normal PAL DVD. There are workarounds for that, but they do cost so much time and the most workflows are bad hacks. If I would blow up the workflow to achive best quality, it expandes postprocessing time to be 10 times longer. And because of all that tech waiting and conversion work you loose the look for the story.
The workflow is is the problem, and thats why I desperatly want the 25p update. The only, but important reason.
>> Technically speaking, the quality will be better if I were to convert 30P to 24 or 25P
Thats not true. Conversion from one frame rate to another is highly problematic and introduces blurring / artefacts. The older, simpler method that is still most widely used is a pulldown, such as a 3:2 pulldown. Its really nasty and essentially blurs frames together which introduces ghosting. Most NLEs still use this method.
The other method is to use intelligent retiming which interpolates through flow. This is very complex and slow and doesnt work in all circumstances. It can also introduce artefacts.
Thats why its important to shoot at the native rate you need. If the 5D2 shot at these rates, there’d be no discussion here.
“Can’t we just get along the idea that a DSLR is not a video camera?” Sorry, but now that video exists on this DSLR it NOW becomes a video camera.
