MP4 not working in After Effects

[pvmetal]

The MP4 codec does not exist in After Effects on my computer.  Everything I can find online just says to install the Quicktime Player.  I did this multiple times, and nothing happened.  Any idea what to do?

Are you a Windows user? What OS you use? Would you mention more information of your PC environment? Can you play the MP4 movie by other players like VLC player?

That is the computer I'm using, except mine has 32G Ram.  Videos do play in VLC Player, but not in Quicktime or AE.  I recently found out that no videos work in AE, not just MP4.  I tried AVI and a JPG sequence, and they all do the same thing.  To clarify though, the videos do technically play, but they are covered with green.  Sometimes part of the video is barely visible.  I also tried exporting a video and playing it on a different computer, and the output of the video is also green and indecipherable.

Try to re-install the whole cloud and turn off addition AV software, if any.

Formerly I always had K-Lite Codec package on my computer, but I don't know if this is helpful in this case. AE should playback everything right out of the box.

Thanks for the reply.  I have uninstalled and reinstalled AE several times, and I even reinstalled Windows.  I've tried every idea I could find on the web to fix it with no luck.  I also just installed the K-Lite package to see if that would do anything, and it didn't.  I'm lost on this.

Odd.

Does Premiere work?

It does the same thing in Premiere. I already tried reinstalling Windows, is that what you mean?

On a fresh Windows with a fresh Adobe cloud, there shouldn't be any issue. I can only think of GPU drivers. The one Windows Update downloads is not always the latest, not always the best. Get the Nvidia studio driver for your card and if this isn't solving anything, get the game ready driver and check if there is any difference.

If this isn't helping, reach out to Adobe support.

That worked! I got the latest NVidia driver and everything seems to be working fine now. Thank you!
