Vimeo’s video file up-loader is well known for being very slow. Tortuously slow.
Fortunately, Vimeo now supports importing video files from DropBox. Go to Dropbox.com and set up a free account. Then copy your video file to your local Dropbox and wait for it to synchronize to the Dropbox cloud. Once done, go over to Vimeo, choose Upload and select the Dropbox option. Vimeo reads the file over from Dropbox very quickly – this is so much easier than dealing with Vimeo’s uploader.
