I've been waiting for baited breath for this to get ported to the Mac. Then I forgot about it for a while.
Nic needed a video creating for her Bed Med Gold Audio and iMovie was playing up a bit. So I downloaded the beta version from www.lwks.com and installed it. Well to say I was amazed is an understatement. After watching a few training videos (the one above included), it took me about 5 minutes to edit everything together and set it rendering.
She wanted one of the Electric sheep rendering videos as a background and that took a long time to download and re-encode.
Here's the finished result (no award for film making yet!)
