I suspect there is an issue with Office365's Onedrive corrupting videos produced by Skype. I used my Onderive to move a video from one PC to another. When I downloaded it the file was corrupted and unusable. I can no longer post a video of the tutorials to my students who were unable to attend.
Has anyone else seen this or a similar issue? I am posting this because I have a vague recollection of this happening before and I am wondering if this is a known issue with Skype videos at 15 fps.
