Vuclip Video Search promises to search multiple sites at once to find videos, but the search results don't seem to support that premise. If it does stumble into the video you're looking for, it doesn't even have a built-in video player to play it.
This site pulls together videos from YouTube, Flickr, Vimeo, and other popular video sites. Though it looks for videos in multiple places, our test searches didn't get good results and it often matched only one or two words even when we used a video that was on one of the sites. More often than not, it seems to ignore your search altogether. In many cases, the search results included videos that had been deleted or were no longer available. Since Vuclip Video Search doesn't have a built-in video player, you'll have to have another video player to actually watch anything that does work. If you really love a video, you can share it on Facebook, Twitter, or in a text or e-mail.
If Vuclip Video Search offered better searching or a built-in video player, it might be worth using. As it sits, there's no reason to use this app over a Google search, let alone other video aggregating apps.
