Direct video uploading
Availability to add videos to Content Library as files and upload on the document not through the links but from the files (e.g mp4)
Nick Navara commented
if there is no link and it's as a file, user currently cannot upload it. You won't be able to directly upload the video to the document. It needs to be on a third-party video provider like YouTube. This makes it more difficult to send examples that aren't published online.
