Imported videos won't play
I'm importing an MP4 video into my AE composition to be played on top of another video, but whenever I add the video to my comp, the primary video area either goes gray (disappears) or simply stops playing anything. Like, nothing plays. I have to revert my file to get anything to work propperly.
Weirdly enough, when testing the same videos in Premier, everything works fine. So, it's def. an AE problem.
Stesp I've taken:
- Done everything here: https://community.adobe.com/t5/after-effects-discussions/my-after-effects-preview-is-all-black/td-p/8307052/page/2
- Cleared cache
- Updated memory preferences
- Re-started my machone
- Scoured the internet for feedback
About my machine:*
- Mac Pro Desktop Tower (2019)
- 3.2 GHz 16 Core
- 96 GB Ram
- 8 GB Graphics card
- 4 TB HD
I've heard that MP4s can be tricky, but I've convered them in Media Encoder to, what I would assume would be Adobe's preferred codec/ouput (since they own the bloody software).
Also, when I duplicate the primary video layer (also an MP4), it does the exact same behaior. When it's just one video it works flawlessly.
I'm at a loss for why layering video files in one application (Premier) works when doing the exact same thing in AE doesn't. I'm also at a loss for what could be causing this issue.
Thoughts? Ideas?
* Even though I've taken steps to clear cache and adjust performance, given my build I don't think that's actually the problem here.
