YouTube may be the best-known mainstream video-hosting site on the Web, but it’s certainly not winning any awards for the visual quality of its content. YouTube’s creators have said higher-resolution videos are on the way, but until then, there are a handful of other services that do a much better job at making your uploaded video look a little less Webby.
The four sites are: Viddler, Vimeo, Facebook, and Veoh. All let you add files in excess of 200MB
-Viddler was the best of breed for its interface, which is all business. It lets you pick your video and start uploading before filling out any forms. When it’s actually time to fill it in, tagging and categorization are simple and intuitive.
-Vimeo’s uploader was a cinch to use. You can start uploading your video file without even having to give it a name.
-Facebook. Very easy to get going, unless you’ve got a lot of people in the video. Facebook’s prowess over the others is that you can tag people who are in it, which doesn’t take long, using the built-in search-as-you-type box. It also lets you start uploading before filling anything out
-Veoh. Simple setup, though like others, you have to do the naming, tagging, and categorization before beginning the upload.
