Hello @chuckyboilo,
Agreed it would be a huge time saver of senior staff… Comp Sups / VFX Editors round the world might be grateful for such a tool…
Did not know about ColourLabAI. Thanks… This looks promising, it has batch CDL export. The X01 format appears to be a IDT, LMT and ODT (rec709) in a single file? Even if this was somewhat manual, it would still be an advancement on what most studios do to neutralise the images. It has aces, but only ACEScct - so would need to do some testing to check this is accurate transform.
I ran a model (50frames - 15min) and worked out how to return CDL values to a 0.00088 accuracy using copyCat, when feeding back a same frame, same grade, and 0.0447 accuracy of a different frame the same shot of a different grade. (but with the same grade amplitude range). It needs extensive training, testing and optimisation before knowing if this is a viable model to train lots of different image pairs on. But the basic premise checks out. We can use ML to reverse engineer CDL grade values (in a very limited scenario I’ve tested it in so far)
I’ll reach out the foundry and see if they can advise, before I throw loads of CPU/plates at it to do more extensive testing.
