I've always seen Vimeo has a higher quality version of YouTube. It's always easy to find absolutely stunning video pieces, whether they be 3D renders or mini movies - you're not overloaded with videos about kittens.
Vimeo announced there would be a redesign coming in January and only limited it to a few lucky people. Now however they've made it public and available to everyone, and must I say, it looks amazing. It's been made to look a lot more user friendly and fun. The homepage has crazy drawings as the background and there are huge fonts, thumbnails and buttons.
Actual video pages have been completely changed and now the video takes up the whole page, instead of being just a block on the left. It looks a lot more minimal too, so you can concentrate on the video instead of being distracted by like buttons and comments like on YouTube. It's only once you start scrolling down will you see likes and comments.
Head over to Vimeo and check it out.
