That is 3 measures per player. To keep the tempo consistent, everyone would need to play to a click track or drums, etc.
To find the right 3 measures, everyone's entire 3 minute video must be listened to so that the best bits get picked. It's 45 minutes to simply listen to everyone's video once after all the videos are loaded into the video editing software. I have no idea how much time it takes to load in, presumably not too long. An hour maybe? Couple of hours?
Then phrases have to be picked out. Playing each video several times and taking notes is typical of what a video editor does when putting together scenes in a video, movie, or TV show. It can take a day or two, or a month or two, depending on how picky the editor is. This is complicated by the fact that 12 seconds is not 4 bars, or the eight bars more typical of a section of a song. So there have to be interruptions to single phrases. This will not be as easy to keep track of without getting confused as it might appear. I know, I've done it with audio, and I'm very experienced at audio editing.
Your best bet is to limit the number of players so that everyone gets at least four bars. It's just musically simpler.
Once all the three or four bar phrases are noted and selected, it's time to cut all the videos into the 12 or 16 second bits. Again, each video has to be watched at least to the entry and out points, and cut precisely on the beat. Then assemble them; this might take a few hours if all you want to do is line them up; the problem is the transitions.
But you don't want huge audio pops and blips, so everything in the audio must be aligned on the exact beat, and crossfaded. Picture must also be edited correctly. As I said, I know nothing about picture editing, but presumably cuts instead of crossfades would be ok and faster to do.
Based on what I've seen in the ad world, I think a good video editor could probably put together a rough cut in 4-5 days, and then the finish details could be completed in another couple-3 days. I have zero idea how this might play out for a hobbyist - and a lot depends on how detailed and good sounding one wants this to be. An ad-world pro editor is a different breed of cat when it comes to professional looking video.
But I'd guess it's at least a good 40-50 hours of work even if you don't want high quality output.
Am I way off on this estimate, Mike?
