I am working on a animation and encountered something weird. In some frames there are these strange black lines showing for 1-2 seconds. Please see the screenshot.

 

I am curious what causes these lines to show.

 

Specs of my composition:

1080 x 1350 px (4:5/0.80 aspect ratio)

Square pixels

30 fps

 

After Effects version 25.1.0 (Build 68)

The black lines in your composition could be due to corrupted frames, graphics driver issues, or glitches in the preview rendering. Try purging the cache in After Effects (Edit > Purge > All Memory & Disk Cache) and ensure your GPU drivers are up to date. If the issue persists, check for any plugins or effects causing conflicts and render a test output to see if the problem exists in the final video.
