If they want to release this as a DVD then I definitely wouldn’t go with a FOH board feed unless they are using a digital board with a matrix output. A matrix board will allow the engineer to give you a seperate mix than what the audience is hearing. It’s still risky but will give you better results than a straight FOH mix. The other issue is you won’t have room mics, without them the mix will sound flat and you won’t get good audience response or room ambience. The cheapest solution is to record the stereo mix to 2 tracks of a multitrack recorder and feed 2 room mics to 2 seperate tracks of the recorder. At least that way you have some control in post. The only other alternative is to hire a sound company that does on location multitrack recording and leave everything up to them. It sounds like you wouldn’t be comfortable doing the audio yourself and since this is a live event, you only have one shot. I would most definitely get a price from a mobile recording company. For a 24 track recording including mixdown and mastering, plan on paying anywhere from $1500 to $4000.
As far as video, Beta SP will suffice. I would switch it live as well as record straight to camera. Make sure you have a backup recorder too. We usually record to 2 recorders, as well as in camera tapes and a standalone DVD player taking a stereo feed. That way you can give the client a spec DVD right after the show, they love that!! You will also need a com system so the director can communicate with the camera ops. Sounds like this will be equipment you will have to rent. I use a company called Video Equipment Rental. They are worldwide and can get anything you need for a reasonable price within a day or two.
Make sure you test everything out at least a day in advance in case something doesn’t work. And also make sure your recording audio to all the cameras to help with syncing issues in post. One more thing, be prepared to loose at least a year of your life due to the stress. I gig like this is not for the faint hearted. If something goes wrong the day of the shoot you need to think fast, always have backups for your backups. Apologize to your crew ahead of time for yelling at them because in the heat of the battle you will yell.
I’ve done quite a few of these for some pretty well known artists and believe me, while they are exciting, they are also one huge PITA!! Let me know if you need any more info.
