Hey Mike (video scribe user) I too have just experienced the same problem you are addressing. Before I read your suggestion list, I did everything you mentioned, including creating a test file using only (4) library file images. Still I get a message that says: "The video failed to process. Please make sure you are uploading a supported file type." It is 8/18/16 @ 11:07 pm here in Ohio (U.S.) and I have a preview deadline tomorrow morning on YouTube. If I can't get this thing working, can I save the file to a thumb drive and have the viewers play it from a laptop??? If so, do they need to have access to my Videoscribe account info?
Mike - Billy here again. If you have an immediate answer that can save my butt - please email me @ firstname.lastname@example.org.
