So there's metadata in those individual files? PNGs, JPEG2000, etc.? Can you point to some details on this?
And for my work, 8-bit is lossless. However, I believe some of those codecs have > 8 bit support (e.g. lossless JPEG 2000).
But if you wanted to use those codecs, why couldn't you?
None of these are supported by Fusion, at least in the output selections. Even Resolve only supports a few AVI codecs, but none of these. But I assume this is all that QT provides.
Or more importantly, why can't you just use image sequences? They are actually lossless, can be randomly write accessed by multiple machines, even allowing you to read while writing, and they compress just about as well when using filesystem compression.
Given that this is the only choice that, that's what we do use.
But as mentioned above, this requires a new subdirectory for each effect to avoid polluting your main project directory.
Yes, these can be compressed, but the random access is pretty poor (on my workstation) compared to a single file.
This is just a preference...a choice I'd like to have (and apparently some others as well).
