@coriander fur youtube videos, the v= part needs to remain, as it specifies the video ID; all other query parameters can be deleted. you may wish to preserve the t= parameter if you intended to link at a specific time
youtu.be links are followed by what would be the v= argument as just part of the path under the root, instead of a query parameter
examples of valid youtube links (with spaces removed, obviously):
https:// youtu .be / rEcOzjg7vBUhttps:// youtu .be / rEcOzjg7vBU ?t=49shttps:// youtube .com / v=?rEcOzjg7vBUhttps:// youtube .com / v=?rEcOzjg7vBU &t=49s (you need an ampersand between query parameters)@coriander ah,
