Suggestion: Vimeo Uploader
I'm sure this has been discussed and considered before, so I'm just casting a vote here...
I see Hitfilm has a built-in YouTube uploader, which is of course quite handy.
A Vimeo uploader would be a nice addition. It seems Vimeo is a higher quality service, designed more for video artists, such as the typical Hitfilm user.
YouTube seems more of an "everything and anything by everybody and anybody with tons of ads slapped on top" kinda service. Nothing wrong with that, serves it's purpose, but when I think high quality video art, I think Vimeo.
Just my vote.
