Updated to AE 18.2.1 Build 8, MP4 h264 video is green.

Video is green, preview is green. Changing project color depth or interpretation of video doesn't help.
This format used to work. ...seriously, I'm just trying to crop a video which sould be a 15 second task. 20 minutes later, I have still not gotten anywhere.

I would guess it is the graphic card driver issue or codec issue. Would you update the driver of your graphic card first?

Hi anders_hattne,

Sorry for your issue.

What happens if you go to After Effects Preferences > Import > uncheck "Enable hardware accelerated decoding" and clear the cache (Edit > Purge > All Memory & Disk Cache).

Let us know if it helps.

Thanks,

Nishu
