What happened to Canon 7D RAW video

I remember there was a post a while ago saying they were testing a canon camera in europe that could shoot RAW. was that just a joke or did someone really have a credible source, because the rumor kind of just died and i can't find any updates on it.
 
Remember this too, but didn´t say anything about a "7D" RAW, or?
Maybe it´s the comming 1DsMkIV or the next XL line...?
IBC maybe...

Wouldn't be too hard to implement in the next addition?

I would think it would be somewhat difficult. After all, these cameras are overheating as it is. Can't imagine trying to push the hardware to capture that much more info being an easy task, especially in that small a form factor.

Not sure but I think it's already doing that, it's the compressing down to the codec which is taking alot of calculations.

of course I really don't know what I'm talking about but I do think that might be true.

Its not compressing the full image. Only certain lines from the sensor are actually being read during video record (aka line skipping).

My take is that RAW video can be put into a H.264 "wrapper". However, the profile of H.264 for that would be very different from whats used now. H.264 supports 422 10bit in one of its higher profiles and since bayer sensor data can be split between RGB as 422 respectively, you can trick a hardware H.264 ASIC into compressing it into a nice 422 H.264 container so long as your decompress and decode it the correct way. Sure you'll have artifacts but you'll also have much better DR and 422 color which is the most any bayer sensor can give.
 
So what your saying is it might be possible to have a 4k resolution 422 h.264 file from these cameras? I mean if that were possible it would at least cut out some of the aliasing and moire effects i would think.
 
i wouldn't count on getting raw from these HDSLR cameras. The development and design of something like this is massive... look at red, Its essentially that, DSLR style sensor, that records RAW. Look at the size, and complexity of operation, workflow, bayer/debayer etc...

....And it still isn't perfected.

Hopefully more dedicated camera systems like the AF100 will address the main issues.

Ya if only they didn't have to line skip, if there was just a way ha

There is a way -- build a sensor that's actually designed to operate at the frame rate that they're asking it to operate at.

Line skipping comes about because they're trying to run an 8fps sensor at 24 to 60fps. If they just build a sensor that's capable of operating at 24 to 60fps in the first place, they won't have to line-skip. But at today's technology level it's highly unlikely you'll see such a sensor in a $1699 camera! More like $17,500 (as in, that's exactly what the Red One is, a purpose-designed sensor that's designed from the ground up to deliver 4K res with no lineskipping at a full 30fps).
 
I'm wondering if the OP was actually thinking about The Syndicate? Their tool is supposed to create a 4:4:4 video from the 7D's 4:2:2 HDMI output. I've downloaded their sample video and the colors do look rich.
 
Even RED's second generation camera with a similar size sensor (The S35 Scarlet) is probably going to be in the $15k range with everything needed to shoot but the lenses.

We are probably three sensor generations away from having something even 5Dish in price that can shoot RAW 24p video in a DSLR body.
