We have added video "fixing" for generated videos so Meta is happy now. We continue to monitor.
That's, by the way, why you need Postproxy. Your posting pipelines continue to work on Saturday even after some social platform engineer deployed something and left for a weekend. We carefully investigate, find solutions and add it to our kit of another dozens of similar solutions that keep it all working.

Investigating
Currently Meta occasionally doesn't accept some of videos. The issue is escalated (https://developers.facebook.com/community/threads/4483580438632946/) and we're awaiting for resolution. Some accounts are more affected than others. The ratio of failing is around 3%. Images posts are NOT affected.
