My fault. The string is created in another shell. It works fine on the
ground, exactly as in your example. I had to combine the scripts.

"${v##*.}" gives everything past the last dot.

So in your case - as you want the file extension - the best
bet is "${video_id##*.}" which will return "mp4".

Works perfectly. Elegant.
