I've been trying out to do live recordings of visuals I've created for stage to the band Montag Mania. I have made the set-up in vdmx and am using Syphon to record it and I think it works really great. (It also turns out to be a really quick way of producing music videos...you just need to rehearse a bit in advance). I need to export the file to 25 fps with Quicktime to keep the sync in Final Cut.
I call it one shot videos and here is an example of how it looks.
