Hello @Austen2
Thank you for contacting the Instructure Community. We're sorry to hear you've been experiencing issues with your video. There is a good likelihood that the video never made it to Canvas servers and is gone unfortunately. Did you record it in the course or using the main Studio icon on your far left navigation? Is it there now or nowhere to be found? It was likely your internet browser and we recommend clearing the cache and cookies or trying another browser. Any lapse in connectivity, browser or device, issue, basic internet timeouts, etc. can cause a disruption and make the video not upload correctly. Anything longer than a couple minutes should be recorded where you can have a backup and not fully reliant on your internet connection - phone, direct on computer, etc.
You're welcome to contact Canvas Support who can look into the video, but full warning it may be lost.
