Importing bit depth bug CC2020

I'm using the latest release of AE (17.0.6) and I've noticed that After Effects erroneously labels imported files of 10 or 12 bit depth as having "millions of colors" instead of "trillions of colors". With the same files being imported, build 16.1.3 correctly labels them as "trillions of colors".

Is this a simple mislabel, or does this mean the current version of AE is actually importing these files as if they were 8 bit, and thus degrading the quality?

You need to be more specific what files you're actually importing, where they were generated and so on. Some of that stuff is dependent on metadata and the automated footage interpretation rules, so something could have changed there.

In this case, I was importing 25fps 3.2k Prores 4444 files from Arri Amira (two different individual cameras from two different shoots, in fact) and 25fps UHD Prores 4444 XQ files from DJI Inspire 2. These are raw files straight from the cameras.


On further investigation, I've found that this bug does not replicate when the footage is Prores HQ from the same Arri Amira. So perhaps this problem only applies to Prores 444.

Hello! 

I noticed that bug too. When I i'm importing these types of files:

mov ProRes 4444 10bit

mov ProRes 4444 XQ 10bit

mp4 HEVC 444 10bit/16bit

Adobe After Effects interprets them as 8bit and shows Millions of colors instead of Trillions and unwanted banding appears.

This is a major bug!

when exporting a prores4444 files with Trillions of colors turned on in export (16bit project setting), the files is detected as Millions of colors.  The banding is impossible to work with.  The 2019 version don't have this bug so that is the only workarounc for now.

Note: This bug is the windows version.

I just tested AE 17.1.4  (build 37)  running on windows 10 without any luck.

Importing prores 4444 files that are saved in Trillions of colors are still imported as millions.

This degrade the footage alot.

Workaround for now is going back to AE 2019.

 

Best regards,

Jakob Eriksen
