If you mean colour editing, yes. But the shadow and highlight recovery isn't really good unfortunately, it produces some halos.

I just downloaded the Capture One 7 trial and with that it doesn't flicker. Shadows are nice, highlight recovery is a bit worse though. It looks a bit like the "Shadows/Highlights" effect in AE. Also it's an awkward workflow. But on my 5dm2 it does the best demosaicing of all, even better than ACR!

yeah but the curves don't really "recover" anything, you could as well apply them outside of ACR. It's a pity that resolves demosaicing is so much worse, because you can kind of mimic the ACR highlight recovery in it. On my 5dm2 it introduces really bad aliasing on narrow lines which doesn't appear in ACR at all (except for brick walls and those things of course).

I tried every process (2003, 2010, 2012) and each of them shows flickering when applying shadow / highlight recovery, but they do it in a quite different way and in different "situations". In the shot I used for testing there is very dull lighting in the beginning and then an overexposed window gets into the view. The 2010 process produces a completely different image as soon as the window is slightly visible ad then stays exactly the same. So it seems that it's based on the brightest point in the image. Actually I made an example video showing each process but when rendering somehow ACR applied the 2012 setting to eacht of the clips. As I don't want to wait out 10min. rendering again + 40 min vimeo conversion right now I upload it again tomorrow.

Also I thought that the shadow / highlight recovery somehow uses blackpoint / whitepoint metadata (that might vary frame to frame ??) to determine its paramters and that we could somehow override those, but this seems unlikely as the flickering also appears in cinema DNG converted sequences which have an explicitly set blackpoint (e.g. 2037, 16000 for 5dm3)

General Help Q&A / Re: Flickering during Raw video.

I think this is because you probably converted this with ACR and used shadow / highlight recovery. ACR is not made for video and those settings somwhow depend on the image content.

thanks, the .RAW file was 1.03 GB, I recorded in 1880 x 1058 but croppeed it to 1:2,35. I think this was actually the max. length on my Komputerbay 64GB 1000x at this resolution (may 29th build).

Hey guys, what do you think about this clip? This look is definitely something you can't achieve with h264 video. Not for everyday use of course but maybe for something like a music video.

#33
Hey there, this stuff looks very promising! Is there any example video of the 5Dmk3 shooting 60 fps RAW? I've searched everywhere but found nothing.

Edit: I've read that the Raw data comes in a 14 bit linear format. If I understand correctly, it would be necessary to convert to a log format when using 12 bit to avoid losing dynamic range. Is that the problem?

did I get it right there?

Of course there's a slight advantage of 14 bit over 12 bit, but I'd definitely prefer to have 1080 instead of 900 lines over having 14 bit instead of 12 bit recording depth. The Black Magic Cinema Camera also records with 12 bit and I haven't heard anyone complaining about that. Maybe an option to choose between 14 bit and 12 bit would be a good thing to add.

Take a look at this ...

http://www.cambridgeincolour.com/tutorials/bit-depth.htm

are you referring to the "bit depth visualization"? That "12 bit" image shows a 4 bit per channel bit depth and we're talking about 12 bit/channel here ;-)

Hey there
this question has probably already been asked, but whats the great advantage of 14 bit vs. 12 bit RAW recording? If people have problems with 1080p on some cards but get it working nicely with 900p, why can't you just reduce the bitsize and therefore storage / datarate requirements? Sure 14 bit give more colors to work with but I can't imagine any situation where 12 bit is not enough. Am I missing something?
