Today's Tech Gospel is about the FaceTime for Mac Beta. Finally. I think everyone found it odd that the iPhone 4's FaceTime app couldn't make video calls to Apple's iChat Video system.
Thankfully Apple reacted quickly and has released a crude FaceTime Beta for Mac.
Now, understand that this is still in Beta, so a lot of features are still a bit buggy, and there is a known security flaw. Not a big deal unless you frequently allow other people to use your computer.
This, however, is a Snow Leopard only program. If you haven't upgraded yet, now would be a good time to do so.
For those with Mac Minis, or a Mac Pros, you can use Apple's LCD monitors w/ the built-in camera, iSight camera, or any Firewire video camera lying around. If you want to buy a webcam, make sure it's the newer UVC compliant webcams. But I prefer using a proper Firewire video camera w/ a boom mic to eliminate room echo and much better audio quality.
My FaceTime rig is my old Canon DV cam w/ a Rode shotgun mic connected to my Mac Mini.
