1. I set my first keyframe (dropdown>add keyframe>show in viewer>etc.),
2. Move some stuff around (dropdown>add>yadda, yadda).
Is that the best way to do stuff or am I making this a painfully slow process compared to ae?
Behaviors are a great way to animate if you don't need frame-accurate synchronization. You can always convert a behavior to keyframes to give it better synchronization.
If you want to work in keyframes, you can turn on the AutoRecord button (the red button at the bottom left of the Canvas controls) which will automatically add keyframes as you change properties on different frames. If you double-click the button you can get to the settings and have it add keyframes only to properties that already have keyframes--this is a safer way to automatically keyframe properties.
Again, many thanks for your replies. Hadn't really worked with, or tried using behaviors rather than keyframes. Still have miles to go before I sleep, or put to bed this thing called Motion. Great tool, as is the entire FCS suite. Now all I need is a great deal on a DVX 100...
