Stu mentioned via Twitter that Vimeo does a really crappy conversion to only 24p and YouTube is far superior. That said, I decided to try it. Here’s the same vid; same file; same everything: one on Vimeo, the other on YouTube. It’s about 7 minutes long. You tell me what you think looks better.
Caveat: You don’t have NEARLY the security features of Vimeo. YouTube is sort of “post at your own risk.” I also don’t like the community of YouTube at all and much prefer the professional and respectful community of Vimeo. Regardless….
