I have a video whose URL has already been distributed, but an edited version of the video now needs to replace the existing one. Is there a way to replace a video in an asset library while maintaining the URL? This can be done in Vimeo, but I can't find a way to do it in SharePoint.
I also had this problem. What worked for me was opening the video library in Explorer, then navigating into the folder with the video's title to find the actual MP4, making sure the filename of the new version was identical, then copying the video in through Explorer.
After some thinking, I got a prompt to Copy and Replace, Copy but don't replace, or Don't Copy, as one would expect with a file transfer. My Explorer window kept freezing up, though I don't know if that's related or if SP was just being weird today.
It did take FOREVER to upload, and seemed to get hung up around 95%, but it did eventually work. I went back to the library and can play the new version of the video and there were no issues. Checked the documents that linked to the video and the link remained the same.
