This is the setup I use to make video soundseeings for the show. The MOTU Ultralite mk3 interface plays the lead role since it serves both as a preamp for Shure SM58 for vocals for comments and as a mixer for the output of Torpedo CAB Two-Notes.
Note that the camera used is a Lumix GH2 with a 14-42 lens. This camera has a stereo mic stereo input required to make a good sounding video.
Be careful though as this input is very sensitive and is quickly saturated if you are not careful.
