Greetings everyone,
I have updated to After Effects 25.0 yesterday and found a serious/maior bug when comparing to After Effects 24. I'm working with large clips of resolutions up to 20480 x 144px. When I import a clip into AE 25, the clip suddenly has black solids at the left and right end. This isn't originally in the clips/artwork and this never happened before, neither in AE 24 nor in any previous versions.
I have attached screenshots from a simple clip of 17664 x 144px that is only imported into After Effects, so I'm not talking about misinterpretation of existing project files or any of that. Simply drag & drop the clip in After Effects. As shown in the screenshots, After Effects 24 does it right while After Effects 25 adds black solids at the left/right ends.
