more gracefull error on using yotube videos urls not channel

hello, by mistake I used a video url ... ok fair it should be yt channell but ideally having a better error msg like - `dude I support oly yt channel urls, not videos` would be great  ``` (venv) xsazcd@obar1:~/yark$ yark new muski https://www.youtube.com/watch?v=uikbWMT8Rgk ``` I guess same behaviour with any yt video link
