mp4 not playing after download

[jheinen77]

I've never had a problem downloading a meeting recording to my computer so that I can upload it to my classroom website until now. I downloaded it like usual (I record them to the cloud), and I can't play it in QuickTime. I also need to edit the video before I upload it. Any help? I use a Mac.

Sad that there is no reply to this. I just downloaded all the .mp4 files form the cloud and none play. Im trying an upload to YouTube to see it the meta files get fixed.  Any advise on paying the downloaded video recordings? Will uploading to YT fix the problem?
