I'm trying to share a video directly with one person and every single format I upload in displays this error. What format do you need to properly preview videos on Drive?
It actually has nothing to do with formats. Google Drive appears to have a bug when trying to use multiple Google accounts on the same machine through the dropdown list, e.g. uploading to the drive of your personal gmail account when you have a different work account that you use 90% of the time. You can tell this is the case because clicking through to the video itself will give you a 403 error even when you have proper credentials.
- The easiest solution is use incognito mode, sign in and you'll see the video properly previewing. It's actually not a video format problem at all.
- Alternatively, you can sign out of all accounts other than the one that you need for drive.
