Canon EOS-1D X Mark II Video Frame Rate Options

[Canon Rumors]

<p>The above image shows some of the video options for the Canon EOS-1D X Mark II. </p>
<p>We can confirm there is no C-Log on the new camera.</p>
<p>We can also confirm again that there is touchscreen functionality for AF when shooting video. </p>
<p>This may not be all of the available options. </p>
<p>More to come….</p>

I also dont see a 120fps in 1080p either. Perhaps that isn't the full menu selection.

interesting 4K@60fps is going to make it hit among a lot of video shooters. also as long as its full sensor 4K without any cropping it will keep wide angle lenses usable unlike Nikons/Sonys 4K implementation.

the sony a7rii uses the full sensor. it also has "super 35" mode

4k @ 60 FPS is something that neither the new Nikon D5, or Sony A7r II / A7sII can do, they are only capable of 24fps/30fps

and if the canon can do it internally without overheating and in full 29 minute clips, it has both easily beaten on video

What picture? I do not see any picture in this thread at all. What is everyone seeing?

4k @ 60FPS

Its a menu overlay in live view and not the full menu itself so definitely not all the options.

Thanks, Nininini.

Wonder why I could not see it in the original post. Bizarre!

yah, it only appears on the homepage, it's not in the thread itself

Motion JPEG is what the 1D C uses and

employs JPEG compression, every frame in a video track is encoded as a still image. The video tracks are stored in a .mov file format. In order to work with 4K in most NLE programs, you will need to transcode it to a more manageable file size.

 

[Nininini]

M-JPEG:
-slightly lower quality
-requires less processing power
-uses more bandwith
-low support
-takes up more room

H.264:
-slightly higher quality
-requires more processing power
-uses lower bandwidth
-wide support
-takes up less room

I think the choice to use M-JPEG is to bring down the heat, because it needs less processing power because it compresses less.

M-JPEG are literally just JPEG files strung together with audio added. It's a very simple codec that requires little processing power, and it's probably chosen to avoid heat on large sensors. The downside is that it's not as widely supported as H.264, takes up more space, Youtube accepts it, but it turns it into H.264, not all video tags in browsers support it, and streaming from a server is difficult.

I like that the rebels I use support MP4 and H.264, simple format that is the most widely supported.

 

[Nininini]

The fact all the other non-4k options are All-I H.264 (or IPB H.264 if you need even smaller files)...shows that Canon knows that most people probably would prefer the more widely supported H.264 format and the smaller file size, for the same and sometimes even higher quality.

It's just that...for now...they probably need a way to deal with theat, and they are forced to choose the M-JPEG format.

All the Blu-Ray, Television, large news sites, all use H.264 or H.265, so shooting M-JPEG will require converting all your videos if you want to show it anywhere else than your own TV set.

If the 1DC could do 4K DCI with CF cards (albeit at 24/25 fps), does 4K @60 really warrant Cfast?

yah, M-JPEG bandwidth requirement scales up exponentially.

It's less processor intensive generating less heat, but because it compresses less, it requires massive bandwidth.

Getting 4k on large sensors without overheating is a massive challenge.

If the 1DC could do 4K DCI with CF cards (albeit at 24/25 fps), does 4K @60 really warrant Cfast?

Yes. The 1D C's data rate is ~3.6 GB/minute, or 60 MB/second at 25 fps. Assuming no quality improvements (10-bit, higher quality JPEG, etc...) and just a linear scaling to 4Kp60, you have a linear scaling to 144 MB/second, which is very close to the quoted maximum write speed of 150 MB/second the fastest CF cards can do.

Better to have some headroom or else you are not going to get consistent performance.

 

[tpatana]

It all stars making sense.

I'm still hoping for the 720p240 option. Since the picture didn't show 1080p120 either (meaning there's more), my hope is still alive.

If what you say is correct, and I have no doubt it is, then surely they should have gone for two CFast slots rather than the rumoured mix of one CFast and one CF.

It's going to be an exciting few days to say the least.

Canon cites a 500 Mbps data rate at 24fps in its 1D C brochure[1], and that translates to 1250 Mbps at 60fps, or 156MB/s. SanDisk Extreme Pro CF cards has a maximum write speed of up to 150MB/s, and only guarantees a minimum of 65MB/s (barely though for 4Kp24).

I think the 1 CFast, 1 CF card choice is a compromise made for the sports photographers, who own many CF cards and have CF-based workflows that they are unwilling to change. I wish they had taken the Nikon D5 route and just offered two options, but oh well.

I wasn't going to comment till the official announcement... but this image elicited it. So far I like that it's Cinema 4K and not UHD. But kinda down that there is no C-Log.

I also dont see a 120fps in 1080p either. Perhaps that isn't the full menu selection.

Its a menu overlay in live view and not the full menu itself so definitely not all the options.

Normally 1080/120p comes between 4k/24p and 1080/60p.
Hopefully there is another menu that accesses 120fps - also it would be epic if it weren't cropped 120fps like the other cams. Will patiently wait for announcement...
