I often find (ALTA) "URL's" usually of videos that begin with "blob:" and the "URL" normally, however, when trying to load this link I run into the error of that URL not being valid. Taking as an example the TAG and its SRC below:
<video preload="" src="blob:https://player.vimeo.com/0910c487-95db-474b-a452-909659339de3"></video>
I'm getting pretty frustrated with this new URL system.
