Nuke 10 bit update#

And many things I find not particularly useful have been advanced.Р”В«ut there are a ton of other users who are thrilled that those things have been advanced. However, the total number of people with a similar problem from these is relatively a small segment of the total user base. And have been so for in one case about three years. There's several major issues for a couple of my workflows also. instead of fixing such a fundamental ProRes4444 bug then I need to ask myself how long I'm willing to rent broken software! Sorry but sometimes things have to be said LOUD: FIX IT ASAP!Р”Р„nd still I recorded a video for Adobe showcasing the bug:

Nuke 10 bit update#

Sorry to come along rude but if I see that Adobe is using it's development resources to update a homescreen nobody asked for, redesigning the UI Composition Panal nobody asked for, putting lipstic on a pick with an ugly 3D Gizmo instead of rebuilding 3D from scratch with real meshes and proper viewports (that's what the community asked for). This again proofs that AE Uservoice is useless for bug reporting as well as this forum as it seems. WOW it's absurd Adobe knows about this nasty and confirmed bug since June 2020 and is tracking it internally as DVAAE-4215476, there is a uservoice thread about it I already posted, this bug exists in all AE versions including all beta versions since AE 2019 v.16.1.3 and Adobe doesn't care!!! ProRes4444 is still broken although it's the most used codec in post production and this bug prevents entire post production facilities from upgrading to AE 2020. Would be good to hear if you are able to reproduce it. Well, it's not so easy to explain, I hope it was understandable. I have no idea why only this special test fileР’В behaves differently when pushing 'Guess Alpha'?!?

But additionally if I hit the 'Guess' Alpha Channel button in AE's Interpret Footage dialog the black color RGB (Premultiplied - Matted With Color) changes to RGB ! Where do these color values come from? BUG? Doing the exact same test but rendering it with GoPro Cineform Codec the 'Premultiplied - Matted With Color' does not change from RGB to RGB ! It stays where it should at RGB like all my other test files do when pushing 'Guess' Alpha channel. When this ProRes4444 file is imported back into AE like all other ProRes4444 (alpha premultiplied) test files unpremultiplied RGB values are wrong. Only with this combination the following issue happens. It's important to notice that the AE Projekt Color Depth is 16 bits but rendering is done to only millions of colors (8 bit). I rendered the test file with RGB+Alpha Premultiplied and Color Depth = Millions of Colors (8bit) The composition settings for background color was pure black RGB. This ProRes4444 test file was created with AE Project settings: I still need to do some more tests to find out what's really going on but I already found some more interesting things I want to share:Р”Р‡or one of my rendered ProRes4444 test files IР’В recognized something strange:

That proofs it's a ProRes4444 footage interpretation or a footage unpremultiplication bug! They also import and look correct in Premiere Pro.Р”В«ut if these correctly rendered files are imported back into AE for comparison, the alpha channel values for Straight and Premultiplied Alpha channels are still correct and identical but for the Premultiplied Alpha test file the unpremultiplied RGB values are wrong a bit off and darker compared to the original AE composition and the Alpha Straight test file!!! I strongly believe that's bug.Р”Вoing exactly the same test but rendering with GoPro Cineform Codec instead of ProRes4444 does not have theР’В described issue (wrong unpremultiplied RGB values) from above. I double checked the rendered alpha channels Straight and Premultiplied and compared them mathematically by difference and they null/zero out so that proofs they are identical and the rendered alpha channel is correct for both Straight and Premultiplied. It's a ProRes4444 footage interpretation or an footage unpremultiplication bug of After Effects. Regarding the second issue I raised (Alpha Premuliplied bug), I did some more tests and have to admit that it's not a rendering bug how it looked at first.
