Noob alert - How to I record straight from Dolphin (frame dump, TAS, etc..)

[hookonsonic2]

The title is pretty self-explanatory. I have yet to find a way to efficiently record stuff with dolphin. I can play Sonic and the Black Knight at 15-25 FPS, which is plenty good enough for me. When I use FRAPS, the video gets accelerated to 60 FPS, but the sound goes wack. When I use Camtasia, it records correctly, but of course, it records the game at 15-25 FPS. Editing the video to get it all to be 30 FPS would be a hassle. I just want to know if/how dolphin can record stuff right out of the emulator, and at the full 30 FPS.

I'm using r6964
