Eyespot
Appeal: Easy-to-use video uploading and remixing.
Interface: Bright and colorful.  Tagging, forums, groups.  Not a lot of community features.
Editing:  Trim beginning and end, reorder clips on a timeline, add music and photos.
Sharing:  Post to a group, invite a friend to the service (but not directly to your clip).
Verdict: Uploading straightforward and painless.  But: 25MB filesize limit too small.  Mashup features fall short of Grouper's "groovies," and it's not even in the same ballpark as Jumpcut when it comes to mixing and editing.  Not a lot of reason to use Eyespot, in its current incarnation.

Google Video
Appeal: It's Google.
Interface: Typically clean and sparse Google layout.  Uploading requires you download the Google Video Uploader.  Allows you to add plenty of metadata, including a transcript.  You can monetize your content by assigning a sale price to each clip (you can also give users a "day pass," giving them access to the content for a limited time, but not ownership).
Editing: None.
Sharing: See below.
Verdict: Google Video requires a "video verification" process, where your submission is reviewed to ensure it conforms to Google's technical standards and legal policies.  This process "may take several days," so check back for an update.

Grouper
Appeal: YouTube with a file-sharing application built on top.
Interface: For full functionality, requires an application download. Windows Media Player-based (converts other formats).  Ratings, tagging, groups, RSS feeds.
Editing: Create mashups of your videos and photos, set to music ("groovies").
Sharing: Post direct to myspace, friendster, eBay.  Download to hard drive, iPod.
Verdict: "Groovies" are easy to create and could be very popular.  But: File-sharing application seems half-baked (and is undifferentiated from existing options).  "Groovies" will prove much more popular if they can be built online without having to download the app.  E-mail registration system was a pain; had to do it twice to get confirmed.  After several hours, my file was still unavailable, as the service was still "upload processing."

Jumpcut
Appeal: Create, edit, and remix video online.
Interface:  Slick interface feels more like an application than a web page.  Scales all videos to a larger size than other sites, but videos don't autoplay and there is no indication of what portion of the video has already been downloaded.
Editing:  Bar-none the best editing options of the bunch.  Splice your footage, reorder the shots, add music, photos, transitions, even effects--think iMovie in an online interface.  Very, very slick.
Sharing:  Email to a friend, embed in a web page (worked flawlessly in Wordpress).
Verdict: Playing with Jumpcut's features, you immediately understand that the future of online video is here.  No current competitor can touch it.  But:  Get too effects crazy and your video slows down.  Jumpcut doesn't re-render your files with every remix--which leaves the original video quality intact--but playback of edited files is not perfectly smooth. Don't throw out iMovie just yet.
