So when Adobe first released After Effects 2020, I tried opening a 2019 project that I have been working on and saw some scary results. None of the footage was working properly. This was January 5th, 2019.
I posted about it on the Adobe Forums, but the response from an Adobe employee was it is a bad graphics card or the footage is corrupted. The computer is new and the footage and project work perfectly in After Effects 2019, as well as Premiere 2019 and 2020, which made me doubt the response, as did it when someone else was having the issue.
I then recently went on a job, and all of their footage was shot on Alexa, and when I tried to move the footage to After Effects on Adobe Dynamic Link the footage had exactly the same response as as the footage on my home machine.
And it was all ALEXA footage that when imported into Premiere Pro automatically has the unremovable AMIRA LUT added to it.
So to prove that it was not in fact my footage, but in fact Alexa footage today I decided to to download some ALEXA footage from ARRI, and try that out.
Here is the Alexa LF ProRES footage download page, and I downloaded the first video. I took this ProRES clip and opened it in Premiere Pro 2020 and it imported and automatically added the AMIRA LUT just as I thought it would. I then imported that footage directly into After Effects 2020, and low and behold I am getting the exact same effect.
So this is most certainly a bug in After Effects 2020 to do with ARRI Alexa footage and probably something to do with why the damn AMIRA lut is automatically added in Premiere. Whatever metadata that makes the AMIRA LUT is what seems to be causing this. The footage works fine in every other Creative Cloud version.
THIS IS A HUGE BUG AND NEEDS TO BE FIXED!
