Recently the Center has fielded lots of questions regarding iMovie, YouTube and Canvas integration. Putting together a comprehensive workflow to upload content to Canvas was a focus of mine over the last few days, and you can view it here.
As faculty and staff who use Canvas on a daily basis but have other tasks at hand, the last thing you want to worry about is taking extra time to find that video you uploaded to Canvas and if you are running out of your allotted space. I hope this helps.
Good luck!
