Just accidentally found out that Adobe has implemented Cineform quite well in Premiere (this is 2015 version and up I assume)
Watch video below knowing that tests clips are made from URSA 4.6K DNG source and they are (keeping 4.6K resolution):
-Cineform 444 2.2Gbits/sec
-ProRes 444 1.6GBit/sec
https://drive.google.com/open?id=0B5Sgc ... HBtYy1GVm8
Each layer has 50% opacity (there are also 2 file sources for each codec)
1. Full resolution preview is killing my machine for both streams, which is as expected. Even single layer of 4.6K is way to much for my system (although ProRes seams to be bit more responsive).
2. Half resolution makes Cineform case better (but still not workable), and about the same for ProRes.
3. 1/4 resolution makes things interesting- Cineform preview works in realtime and these are 3x4.6K streams! ProRes the same- still just a slideshow
1/8 again- Cineform works in realtime, ProRes the same.
Explanation can be only one (99% sure). Adobe has properly implemented Cineform decoder. Looks like their resolution switch is linked to Cineform decoder which has ability to decode in smaller resolution due to fact that Cineform is wavelet based. So far this lower resolution preview was only available through Cineform directshow decoder in players like WMP, MPC-HC. Looks like Adobe has done a proper job and this gives huge possibilities. When it comes to editing 1/4 res is totally workable (for source 4K files). This is great feature, as there is no need to waste time to create proxy files, etc- they are already there, we just need to change resolution setting
In case of ProRes this is not possible as Premiere always decodes it at full resolution. For DCT based codecs lower resolution decoding is way more tricky- I think FCPX does it for ProRes. Decoding itself is killing my machine regardless of what is happening later and at what preview resolution.
I wish for such a Cineform support in Resolve (including RAW and Resolve debayering for CF RAW)! It could be even linked to debayer resolution, so it not only changes debayer setting but also decoding. It would make 4K files easily editable and workable in Resolve.
Now quiz question- what is my machine spec?
