My band is going to try some projection/visual stuff at our next gig. Our main system for this is an HD projector, playing 1080p video from a laptop (either Mac or PC). Is there a good way to remotely start / stop / change video clips during a live performance? i.e. at minimum, start a specific video for a specific song, then stop it if necessary after the song is finished, wash / rinse / repeat. Bonus points for being able to change the current video midstream, switching to a different one to sync with a significant song change. It should be kind of stealth, i.e. no one wants to have to walk over to the laptop, dick around for a minute to start the new video, while ruining the flow of the gig, etc. A band member wants to be able to control the video via some kind of unobtrusive remote control (the singer who has a free hand to do this).....ideally a 3rd party off stage could do this from the laptop, but they would have to be trained on any software and know the music enough to trigger cues for the video changes. I know that in Micro$oft PowerPoint you can remotely play videos as part of a presentation file, but I don't think that is well suited for this. Anyone know if there's a better system out there for doing this?
