Ahhhhh. Figured you were slaving over editing the entire ceremony and reception on the fly. I'd charge 3-5k depending on certain circumstances for a recap of the day on the fly.
Haha there's just no time; Best case scenario I've got 3-4 hours to pour over several hours of media split amongst several cards(this used to be such a pain in the ass with HDV) and construct an edit to 1-2 songs chosen by the couple.
Worst case scenario, I've got 1-2 hours and that's on top of whatever intro I've already constructed the day before. And the sick thing is I don't know what kind of scenario it's going to be until I'm knee deep in it. Sometimes there's barely anything on the schedule and my highlight IS the "entertainment". We try to push the showing till the very end before the Electric Slide kicks off, but sometimes those speeches that you hope will go for 30minutes or so, end up covering up only 3 minutes, and you're only halfway through with only the cake cutting standing between you and showtime.
Factor in time to setup and to test my connection to a projector that's not mine, as well as to a DJ who may or may not be able to accept an audio output from you or may only have legacy connections such as RCA(fortunately I pack for every possible option they might have).
It can be incredibly stressful but equally rewarding, especially when you've got family and friends coming up to you after the reception's over to thank you and to ask for a business card. I don't book the weddings but refer any inquiries to my employer(some close friends I've met along the way).
If you're good and can command that type of rate of $3k-5K for a 3-8min(approx) edit(no shooting involved), more power to you, but here in Hawaii, that's not going to get a lot of takers unless you're an A.C.E member with many titles to your credit, of which point you've either fallen on some really hard times, or just doing it for family or friend.
The advent of vDSLRs really has introduced an influx of wedding production companies for good and bad. Lower cost of entry is definitely a plus, along with the image quality and shallow DOF with quality interchangeable glass. However, now the market is so saturated(at least here in Hawaii), and the wedding industry, is not immune to the effects of a bad economy. If couples have to cut somewhere in their wedding budget and have to make a decision between photography and videography, I'd wager to say most would axe video and opt for photos only. It's usually cheaper(although photography can be just as expensive if not more than video), and the couple can easily disseminate photos to family and friends, whereas the final edit, will usually only be seen by them and a few family members.
Enough of my ramblings. I wish I could collect that kind of coin but it'd be for a very narrow market someone would be willing to pay that rate.
As for the new Mac Pro, it's diminutive size definitely is a plus in my book.
