I have an instructor that is attempting to post 10-minute feedback videos for student submissions. After he records the video within Canvas, it can take a few minutes to process or just hangs and never processes. I did a speed test with him and his upload/download speeds are very high, so that's not the issue.

Does Canvas have a time or size limit on instructor feedback videos for student submissions? 

Any tips on how he can speed up this process, as it's slowing down his grading immensely.

Thanks as always!
