I can’t get a video (file) into my prezi classic presentation… It is a M4V file but i get this sign after a while:
Use a online editor and convert the file into mp4 first from m4v
I did. I changed it into MP4 with VLC, so the file type is ok now. But still it’s not correctly uploading, it now gives the following error:
conversion with VLC not always reliable. Have you tried any online editor?
