My experience with multi-cam shots has mostly been not pre-planned in co-ordinating others to film, but tracking down others who just happened to have filmed the same show.
I've filmed a lot of Dead and related stuff (phil & friends, ratdog, TOO, Furthur). The Phil show from summer '02 in Camden NJ is one I was not involved with , but I have it and it is a nice 2 or 3 cam shot. I've also seen a 2 ...and later, 3 cam shot of the Jerry Garcia Band show in Hampton VA (11/91) in which Bruce Hornsby sat it - that looks very nice.
A friend of mine has done a lot of video editing (I'm more of a videotaper and leave the editing to others), and was going to work on a Furthur show that I filmed last year, and I know two other people who also filmed it - together we have the whole concert except for two years. Unfortunately the friend that does editing is now an ex-friend - I refuse to deal with him anymore, but that is another story.
Would love to find someone willing and able to do some multi-cam editing on some Grateful Dead related shows . I filmed Other Ones on 9/16/00, and it came out so-so...but I came across someone else who also filmed it, with some limitations, but together both of our shots would looks great ! Again, looking for help on this.
Slightly off-topic, as I guess it was planned to be an official release, but did anyone hear a few years ago how The Beastie Boys supposedly gave out 50 different videocams to fans and asked them to film from various places at the venue, and then give back the cameras, so they could officially release the show, from an audience perspective ?? I don't know if this project ever came to fruition or was ever release, because I don't follow Beastie Boys much, but it sounded like an interesting idea...
