Question Watching videos on Google Drive

I didn't know which subforum was the best fit for this question, so apologies if I posted this in the wrong place.

I like to make videos of my gaming and upload some of them to Google Drive. I make all of those videos the same way; capture via the Microsoft recording program and patch them together via Openshot. I've noticed though that some videos that I upload, their icon turns into a thumbnail for the video, showing a screen from it, and these I can stream directly from Google Drive. Others stay in the generic red "video" icon, and when I try to stream it, it tells me "Unable to process this video," and I have to download it to watch it. And when I do download it, it plays just fine, so there doesn't seem to be anything wrong with the video itself.

I always use the exact same settings to make the video, so I have no idea what's going on. What determines which of these ends up happening? What can I do to change the unstreamable videos to a streamable one?
