    Are there any RAW vs ProRes video comparisons out there?

    I would be very interested in seeing the 2 compared and if shooting RAW does have a major advantage.

    Of course RAW has major advantages, that's one of the main reasons why everyone is so interested in this camera. It also comes with headaches like file storage issues, format issues, etc. There are 2 ProRes modes, one is Film and the other Video. Do some more research on how they work and why/when you might use one of them over RAW.

    Thanks for the response.

    I was just looking for a video comparison of the 2 formats side by side to see the difference, I know there is a difference I just want to see how much.

    Here's one that I did a few weeks ago. The content isn't terribly compelling, but it is "side-by-side".

    In my own tests, I have found the main important difference to me is that the ProRes mode seems to have more colour aliasing on hard edges - most likely due to it having to do a faster and lower quality in camera debayer than is available in post production.

    I have found the ProRes to grade quite nicely - on this image the exact same colour grade was applied. If you flick between them quickly, the raw does have more fine detail - but not so much that I think it matters.

    Thanks for posting the comparison.

    Also if an area is overexposed/clipped, how many stops can be brought back?

    I know for most common DSLRs, photo RAW files are usually around 2 stops.

    Debayering will be the main factor and than maybe also a fact that ProRes ends up as 4:2:2 (after debayering to 4:4:4 I assume), compared to DNG being debayered and kept as 4:4:4 in Resolve.

    To me, which is which is obvious - but I want to be sure its not just because I KNOW which is which. So if any of you will perform a quick experiment:

    Two frames of video, one recorded ProRes Film mode, the other Raw.

    Camera settings: Iso 800 - F4 - Sigma 20mm 1.8 EXDG - 180 Degrees shutter, 23.976 fps.

    Very basic grade in Resolve (Project set to 1920x1080), No sharpening applied. Exported as 16bit Tiff's, imported into photoshop to arrange them -saved as a PNG.

    Which do you prefer/Which looks better?

    A or B?

    A is cleaner, but overall ProRes does not look that bad. If BM improves debayering than it can be even better.
