To be fair to OP, catbox is sort of the defacto "short video hosting site" here, but certain video containers (and maybe codecs?) don't embed properly here. I've had the same issue with x265 mkv I've tried to post here, so I'm assuming a MOV is a no go as well. It's really not OPs fault - there's no option he could have selected to make this "work" outside of knowing what formats ARE supported in advance and remuxing accordingly. Perhaps there's a side bar note about this somewhere; I really should check, but I haven't.
