(First, sorry if it's in the wrong place. It's my first post and have only read Creative Cow when I came from google, but now I want to give something back).
Lately I have bin working with a project that have bin more than messy, and I started looking into different codecs. We haven't really thought about codecs and quality before.
When we went from Mac to PC we went from Prores to DNxHD and didn't think much about it. So we converted film to DNxHD -> VFX DNxHD -> CC DNxHD -> Final Export DNxHD. As you can guess, much quality got lost. Now I have looked over our workflow and our codecs to use and made a small spreadsheet about it that I thought would be good to share because after so much searching I didn't find much else than text saying "this is good, this is bad"
I compared QT Animation, Avid 1:1, Cineform, DNxHD 185 10-bit, h.264 10 000kb/s and 60 000kb/s, JPG, PNG, TIFF och UC10 YUV 10 bit 4:2:2
