Youtube backlink question

Hey guys quick question,
I had backlinks built to my site using this address format:
youtubeDOTbe/__________


but I realize, that when i go through SERP, all the youtube links are in this form,
youtubeDOTcom/watch?v___________



Am i still going to get ranking benefits, or did I link to the wrong web address?

I ask because I haven't seen any improvement in ranking yet..

yes - by defaut links go to the watch extension... if you embed then further extensions get added

That should not be a problem

Since youtu.be is like Google's own video url shortener I suspect it's not a problem to link to that url.

But it's a good question. I've been linking to the latter address in the past because - as you mentioned - it's what pops up in the SERPs.
