what you mean by "We" and hope so, you want canon users to go to Nikon?

lol


from what i understood, Canon has no firmware update scheduled for the 5d3, why would they, they rather have a 5d4 to sell for more money

Andrew Wonder asked the Canon people at NAB a few hours ago and their response was that the new firmware for 5D3 is coming soon, by the end this month for sure.

firmware for 5DIII will be available near the end of the month

Chuck Westfall said in the interview "by" the end of the month?

Canon said this HDMI update was coming out in April 2013.

Any word on this?

I would imagine Canon is likely to release it during NAB (some day next week), to get people's attention and more media coverage. or shortly after NAB.

So I heard Canon Announced that in the April of 2013, or next month, the Canon 5D Mark iii would get an update which would allow for a clean HDMI output. Does this mean that we can use an external recorder such as the BlackMagic Hyperdeck Shuttle for external recording? If so, then can we actually record at a higher fps such as 60p at Full HD? if not, then what kind of impact does this have on videomakers? Thank You in Advance!

It won't give 60p. Hopefully the better compression will make a noticeable difference. Depends how much of the problems occur before the compression stage. Maybe not.

It won't give you noticeable difference, trust me. I'm using Canon 1D C with Atomos Ninja 2 external recorder. if you don't do heavy colour grading or keying/compositing, there is no difference at all.

Would 1DC sensor overheating be a problem with 1 hour of continuous 4K video? I participate in marine archealogy projects and plan to video scan entire wrecks with the limitation of 2x128 GB media, i.e. 1 hour per dive. The 1DC would be housed in a tight aluminium underwater housing with hardly any air circulation. But, the housing is cooled externally by 4-20 degrees Celsius water.

Currently I do similar work with HD video and this is a very useful technique to explore unknown historical wrecks before further research. I have a 200W/16000 lumen HMI lamp, so exposure and motion blur will not be a problem.

I am asking this question due to the 1DC overclocking of the DIGIC processors and additional heat sink(s).

I don't think it's a problem at all as long as it's operating under recommended temperature range.

1D C was designed to continuously record up to 12 hours.

The 5D MK II and MK III cannot do this.  The feature is being added to the 1D X.  You can do it with a Nikon D800.
 
It works by using the HDMI output, but the output is at reduced resolution in all but the 1D X.  This makes direct recording undesirable.

That's incorrect, uncompressed HDMI output will be added to 5D Mark III in April, no plans for 1D X and other cameras yet.

So, after April, 1D C and 5D Mark III are the only two cameras in the Canon DSLR line that are capable of utilising external recorders.

One thing I can't believe is that they are actually running with the $15k price.  I heard it may actually debut at $12k (kind of like the C300 was announced at $20k but debuted at $16k). 

Retail here in Australia is $9,999AUD
http://www.techrific.com.au/canon-eos-1d-c-digital-slr-camera-body-only-1dc-free-gift-12mth-local-warranty-p-2956.html

But I mean seriously what hardware on this thing is any different from the 1DX?  I know it has all the same still features, but I want to know what physical changes they made for this to shoot 4K or if it's just a $7k firmware update.  They said the price was due to "development costs," but they could have sold a hell of alot of these if they had priced it at $8k.

This is why I'm wondering how hard it could be for the ML team or similar to hack the 1DX with the 1DC firmware.
That would suddenly make this a $6500 camera (and have a lot of angry customers feeling ripped off)

the thermal design and some data processing module are different between 1D C and 1D X, the latter couldn't handle continuous 4K shooting, it's the heat and the huge amount of data.

General comment to all: Please donate for ml on their website, everybody who owns a 5d3 can spare at least $5 for the dev even if the download is free now!

They have focus stacking, but not bracketing.
... should be trivial to implement, did you do a feature request on the new forum's section?
http://www.magiclantern.fm/forum/index.php?board=24.0

Moreover, I believe ML will support 5D3 soon.
My standard comment on this: don't get your hopes up, though the 5d3 has the potential of running ml it even hasn't been decided which camera is targeted first, it might be the 650d. And even if the 5d3 is next, first the main dev Alex needs a 5d3 (donate!), and then I predict it'll be at least a year until a *stable* 5d3 release.

Magic lantern is not yet available on the 5DIII, it is in progress and an early version should be available in October.
I didn't read that, where did you get this date from? And remember "early" version with firmware means feature-incomplete and you might very well brick your expensive 5d3 body - if the firmware goes into a loop, the cpu overheats in seconds and that's that.
http://www.magiclantern.fm/forum/index.php?topic=1006.0

Alex has already got enough funding and has purchased a 5D3 body, development will start soon.
I did all the initial testing with Alex since March when 5D3 was released and took that "Hello World" photo, I bricked my 5D3 numerous times and all successfully unbricked. The latest build I tested works really well considering it's done in just a few months, I believe it definately won't take a year from now for a stable 5D3 release.

it would be interesting but doubtful. motion jpg is extremelly inneficient compared to modern H264.

Is it? I have no clue, I'm not really a video person. Just someone who has a small bit of interest. Reason I'm thinking that is the S1 JPGs are a good bit more resolution than 1080p, and I've read some things saying that the 5d3's 1080p doesn't really look like it has full 1080 lines or something like that. Also my random theory is JPEG conversion might require a good bit less processing than h264, so maybe we could get up to 60 fps, at a resolution somewhat higher than 1080p. Wouldn't that be awesome? Plus we know the JPEG engine in the 5d3 is quite good, so quality likely would be great.

Obviously MJPEG has a much lower overall storage/space efficiency than h264, especially when compared to intra-frame compression, but a UDMA7 card likely can keep up with that, maybe even a UDMA6 card. Unfortunately with the 5d3 it doesn't support UHS-I, so the SD slot may or may not be able to keep up.

Motion JPEG is Intra-frame compression, so it's similar to ALL-I mode in 5D3, In EOS 1D C, its 4K mode uses MJPEG 24fps at 500Mbps, considering 1D C/1D X has larger buffer, I think 5D3 can handle 200Mbps properly.

Ah, didn't realize Motion JPEG was all intra-frame. Like I said, I'm not a video guy. Just did a back of the napkin calculation, full individual JPEGs @3MByte per frame, 30 fps, 720 Mbit/sec. Wow! Guess it really does need to use that intra-frame. The JPEG engine probably would need to be modified some for that intra-frame calculations probably, so I'd guess that'd be a hardware change so probably won't be able to do it :(

There is hope for MJPEG recording on 5D3, probably not at that high resolution and 720Mbit, but there is hope.

According to BBC broadcast specifications, interframe compressed footage should be at least 50Mbps, intraframe compressed footage should be at least 100Mbps, 5D3's 33Mbps and 90Mbps is just a tad below that minimun requirement, how smart Canon is!

I've seen 101Mbps in ALL-I on a Lexar 600X CF card (complex tree scene).

It looks like PPro CS6 is doing a better job with ALL-I re: block artifacts (720p60 looks clearly better than IPB), however 1080p24 for non-fast motion still looks really good with IPB (haven't seen a case yet where ALL-I is better).

Maximum I got was 151Mbps shooting a fabric, but it's still VBR, EOS C300 implements CBR 50Mbps interframe compression, it's 50Mbps all the time. This is what Magic Lantern is working on, bring constant high bitrate.

Thanks for all the good info!

Shouldn't fast pans and dolly shots up the bit rate too, since there is so much changing from from frame to frame?

What do you think the perceived advantages of a higher bit-rate will be? Do you think it would visibly affect things like  highlight rolloff?

Since 24bit 1080(like our monitors are capable of) is something like 1.1Gbps @24fps, how come blue ray can look so good at much lower bit-rates?

In ALL-I mode each frame is encoded individually, so in VBR mode the bitrate changes acoording to the scene complexity, eg, a scene of trees full of leaves will make the bitrate go higher.

The benefit of high bitrate CBR would be colour grading, especially when you pull a secondary, there might be less blockiness in the shadow and highlight.

I don't think highlight rolloff has anything to do with bitrate, it's mainly gamma curve, which Magic Lantern is working on at the moment. in the upcoming new release, Magic Lantern digital ISO can improve highlight rolloff.

Bluray material usually comes from very high quality & high resolution master (eg, from film scan, RED or Alexa), the encoded quality will definately look better. However I think 5D3 footage after some processing it can look almost the same or even better than some bluray titles. Both Bluray and Canon DSLRs use H264 which is a highly efficient codec, it throws away a lot of data you can't see.

30
They say they can already control the bit-rate, but only at high ISOs. That's weird. Anyone understand that one?

The bitrate maxed out at 151Mbps at ISO12800, if using normal ISO like 100-400, even if we change the H264 parameter to the highest value possible, there is no obvious increase in bitrate, around 47Mbps in ALL-I, 32Mbps in IPB.

So there is no work around the H264 codec? Why are their block artifacts in ALL-I, if not for insufficient data?

I think the block artifacts is caused by the decoder, 5D3 ALL-I mode uses H264 High Profile at Level 5.1, which is a very advanced and relatively new H264 standard (it supports 4K), thus it requires complex decoding, which might result in blocks in some applications. I use Cineform all the time and haven't noticed any similar thing in my work flow.

As a reference, all previous EOS DSLRs use H264 Baseline Profile at Level 5.0, and 5D3 IPB mode uses H264 High Profile at Level 4.1.

151Mbps at ISO12800 is mostly noise I think. Canon implemented VBR on 5D3 and placed a cap on max bitrate, currently we were able to remove the cap so bitrate can go very high. The next and the key step is to somehow achieve a high bitrate CBR.

According to BBC broadcast specifications, interframe compressed footage should be at least 50Mbps, intraframe compressed footage should be at least 100Mbps, 5D3's 33Mbps and 90Mbps is just a tad below that minimun requirement, how smart Canon is!
