Hey so if you noticed YouTube uploads videos as shorts, especially if they are small animations and this website doesn't like the links keeps asking for a valid link.
here's what to do to work around it.
once uploaded as a short, go into the video settings in studio.
Make a playlist and add the video to the playlist you just created
once you view the video it will display the proper link at the top of the address bar just and case you wondered how.
From there you can add any future short videos to the playlist you created prior to uploading.
:)
yeah i found that but this is a nice work about to use the links in this website :D stupid youtube lol
