You may notice that sometimes I use Vimeo for my videos, and sometimes I use Youtube. My decision process is pretty simple: if the video has music, it goes on Vimeo, otherwise it goes on Youtube. Youtube will cram ads on videos with music, and I don’t want to trouble you with ads.
BTW, Vimeo used to have the advantage in terms of encoding quality. That isn’t really the case any more. The community is still awesome though.
