YouTube, apparently effective March 2021, converts videos of vertical orientation and 60 seconds or less duration to a new Shorts format as their answer to TikTok.
Shared Shorts URLs aren't (at this time) recognized by AutomaticWasher's site software for automatic embedding and playback in posts and must be copied/pasted for viewing. The resultant display page when copying/pasting a Shorts URL for viewing includes unrelated videos that may autoplay when scrolling down.
A regular YouTube URL works better and can be maximized to full-screen when viewing on a computer. A Shorts URL can (thus far, assuming YouTube doesn't take steps to prevent it) be coded as a regular video by manually writing out the URL in this format, written here with extra spaces to avoid the automatic embedding so the syntax can be seen. v= at the end is the specific video ID number, which can be gotten from a Shorts URL.
https:// w w w.youtube .com/watch?v=0HZI2J72eZ4
is the source Shorts shared URL for the above example.
