I have just spent an hour working on a video for my students with visual processing disorders. I forgot something at the end of the video and after I published it I realized that I left something out. I could not unpublish the video. I couldn't edit the video. I had to redo the entire thing from the beginning. Another hour worth of work. You really need to add a feature that allows teachers to go back and fix errors or mistakes in their videos. A simple unpublish feature that would allow us to go back in and edit.
