editing control board with joystick

I think the edit controller you are talking about is by Convergence. We had one at the cable station that I did my college internship at.

The way it controlled the video decks was through 9 pin RS422 which would have to adapted to USB or something then you would have to write code to make the program recognize the commands.

There are these things:

Might work with iMovie.

 

iMovie, being a consumer-oriented NLE, does not support external control surfaces.

I know that FCP supports control surfaces (MIDI, mixer, etc.) for its audio mixer and the other apps (Soundtrack Pro, Color) support dedicated surfaces as well, but nothing to my knowledge for video edit control. About the closest thing you'll get are jog/shuttle wheels, like the products Contour Design makes.

 

I have the contour shuttle pro 2 and its freaking awesome... i don't think I could go back to just using a mouse...
according to the application setting it does support imovie... (i know for sure it works with FCP)

you could try this as its a bit cheaper but you may as well get the contour shuttle express
