Thanks to everyone for all the great feedback. You all present really good arguments on the topic... I think the "best" solution for my app would be to create the temporary account converted to a registered user upon save. Like some of you mention, I will probably end up registering users at some point but I don't think what I'm offering now justifies a sign up... I was thinking about making it very basic, no registration, user can create and save but they have to take care of tracking their own edits... bookmarks or taking the embed for a one time use. I realize it would not be all that feature rich but does it need to be? Light, nothing to commit, like tinyurl with video edits...
