ooVoo is an elegant and powerful video conferencing and IM client that combines elegance with functionality.
Unlike some video conferencing applications, Oovoo is very easy to get running with your webcam and it can handle very high quality cameras - up to 2 megapixels, depending on the speed of your connection. During chats and video calls, you can add video effects such as sepia, blurring and morphing, something that sets it apart from other popular VoIP apps like Skype.
With ooVoo you can talk face-to-face with up to six people, add an ooVoo link to your blog or online profiles (so others can instantly add you to their contacts), send and receive video messages and, best of all, it's completely free. You will need to create an Oovoo account however, which, as registrations go, is fairly painless.
Once you've started the setup process, you'll be asked to create an ooVoo username and password. You'll also be asked to add a few friends and contacts to your ooVoo account although if you don't know anyone using ooVoo, you can simply elect to send invites and hope that they sign up.
What's really nice about ooVoo, though, is the ability to place your contacts, and their video images, down the side of your screen in a sidebar simultaneously. This way, you can chat away to all of them at the same time and see them at once.
Unfortunately, at the moment ooVoo is not compatible with Lion although the developers claim that they will release a compatible version soon.
OOvoo’s an impressive video chat app, although it would be interesting to see how it performs when multiple users are trying have a video conference.
