What is going on in this clip?

This is a very unusual thing I am experiencing while editing a fairly simple project. In the linked clip, you can see what I'm talking about. The video should smoothly transition from the woman standing and addressing the room to the computer lab. The footage of the computer lab is buggy as all get out. Drop drames, dips to other clips, a frame rotated 180 deg. Random as far as I can tell and not pulling that info from anywhere I can see. There are no hidden layers, no effects added. When I play back the original clip in AE it has some of those qualities (as seen in the linked), but the orginal clip itself is completely clean (also shown in linked). I have purged my memory and cache but that has not helped. Can anyone explain what's going on here?
Video Sample

Hi Jason,

Sorry for your issue.

I'd suggest clearing your media cache again and resetting the preferences. If that doesn't help, go to After Effects Preferences > Display > uncheck "Hardware Accelerated Composition, Layer, and Footage Panels"

Let us know how it goes.

Thanks,

Nishu

Hi Nishu,

These suggestions did not clear up my issue. Is it possible the original clip itself is in some way corrupted? It appears to be fine when playing it back in Premiere, VLC, or Quicktime, but it's also the only clip in this project giving me this issue.

Thanks.

I am with Rick. It is possible that the footage itself is corrupted.

Let us know if transcoding the footage help.

Thanks,

Nishu

My first guess is that the source footage is an MP4. Try transcoding the footage to a frame-based production format like ProRez.

It's and MXF from a Sony FX6. I didn't try transcoding, but I did export the clip from Premiere as an MP4 and that did resolve the issue. I had to do that with every MXF file, unfortunately, which wasn't a problem in AE 21.
