Was trying to submit this video in a post using the "Video" post type, and for some reason I get the following error trying to submit it:

"Your post was not accepted because 400 Bad Request: The browser (or proxy) sent a request that this server could not understand."

This is my first time bumping into this issue doing so. Is the option to post videos broken currently, or is there an issue with the video itself? Despite what the error indicates, I've submitted videos through this browser (LibreWolf) before without issue, so I don't believe that to be the cause.
