Update: Apparently, the issue is with the OneDrive app having incompatibility issues with some HEVC videos capture by my Samsung Galaxy camera. It's weird since some videos are fine, some got played as if they are corrupted. And apparently Quicktime on Catalina also have issues with the those "corrupted" videos. VLC and Google Photos seem to play the videos just fine. Phew!! I thought I lost those videos.
I would still recommend turning off Gallery sync and use the traditional Camera upload method, so at least you have a backup instead of direct syncing.
Old: Had some of my important videos got corrupted when they are synced to OneDrive from my Samsung Galaxy phone. The videos become green rectangle. And it's permanent as the files themselves are corrupted. I tried downloading the files on my computer, and they are corrupted. Worse since they are synced, when you delete the corrupted video on OneDrive, it will automatically delete the only good copy in your phone's gallery without any ways to recover it (it won't appear in the Gallery's trash).
So those who have Samsung Galaxy phones, I would unlink and disable the Gallery sync. Use the old style Camera upload backup instead.
