It looks from Canon's announcements like the new pro camera will have 4k recording with dual pixel touch-to-focus servo AF. If it works like the 70D, it will be awesome. Does the motion-jpg format pose any big problems for quality?
mkabi said:From what eosHD.com says about the 1DC which also uses Motion JPEGs for 4K recording, its softer than other offerings like Sony's a7rII. However, the softness gives a more cinematic, pleasing and organic look, but technically speaking some people like sharpness....whereas the color on the 1DC is better and more easier to work with compared to other offerings.
So, you have to ask yourself, how much of an improvement is the 1DX mark II over the 1DC?
Can you settle with softer images, but good color science?
Here is a good article about 4K and above and what one experienced DP thinks about it:

The 1DC has touch screen focus with DPAF?

Why would you want to buy the 1DC (if video is your concern) now that the C500 is $9999?
I preordered the 1DX2 primarily for video (my 1DX can do photo just fine).tcmatthews said:If they were serious about video they would have added a hardware encoder for H264 or included a clean 4k output for external recording. I do not know many people who would buy a 1DX2 primarily for video.
tcmatthews said:I do not know how much it affects quality but motion-jpg takes much more processing power and creates larger files than H264 and Sony's AVCHD. This is because modern computers can off load the encoding of H264 to the video card. So you will need a more powerful computer and disk space to edit motion-jpg. Quality of motion-jpg is depended on the jpg engine inside the camera because it is literally a sequence of JPGs. I have always seen Canons JPGs as just ok I never been quite satisfied.

This is all wrong.
MJPEG is an intraframe codec with pixel-level data which requires very little processing power to work with. H264 is a long GOP codec which uses macroblocks not pixel level data, which means that it's always been considered a nightmare to work with as an editing codec. It was designed as a delivery codec, and is great for that (Blu-Ray/YouTube) but its a pain to edit with. GPU acceleration helps (as in before you couldn't typically play H264 files in Avid/Premiere beforehand), but H264 is still not really an editing codec, most professional workflows will convert to something more friendly (Prores or DNxHD) before working with H624 material. So H264 requires a more powerful computer to work with directly than something like MJPEG, which is the total opposite of what is argued here.
And AVCHD, MPEG4 and H264 are all the same thing. https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC
The fact that intraframe codecs take up more disk space is not an argument for not using them either. That you argue for an external recorder (which would use an edit friendly codec which will take up more disk space) suggests that you are aware of this though. To illustrate, DCI 4K DNxHR at 60fps tops out at 3730mb/s, and the 8 bit 4:2:2 HQ version you'd be more likely to use for most things is still 1865mb/s. Not the 100mb/s you see on Sony/Panasonic cameras.
But if you really need that, you're probably in the market for a c300 ii not a 1DX ii. And spending a small amount on extra disks or server storage for your ISIS/Terrablock at that stage is spare change.

If you are asking me, I personally couldn't afford either one. If I was to choose, I would still choose the 1dx mark 2. But, if I could afford it and I only had the option between 1DC and the C500, I would still choose 1DC.
Because the C500 is still $2000 more than the 1DC, C500 is super 35 sensor vs. FF of the 1DC...
and even though the C500 has 4K option, its not internally. That is, you need an external recorder to get 4K from the C500. Whereas the 1DC has internal 4K.

If you can spare a few minutes to share some of your video expertise, I'd be very interested in what your thoughts are on the 1DX II as a singular camera used primarily for stills of birds/wildlife etc. but providing the ability to capture some video of the same subjects as well as the surrounding landscape.
I've been doing mostly stills and hear lots of comments from folks on CR that they don't even want video capability, but to my way of thinking seeing some action (behaviour) associated with the birds/wildlife I shoot as stills, is very rewarding.
