Okay I was wondering what the best way to get the best sound for filming a short inside a car?
Not sure if this is appropriate for your movie, but I've got a project in post where an entire scene takes place inside a large Ford medical transport van. The van is supposed to be moving and the actors need to be talking. Here's how it's broken down:
1. Filmed exterior/establishing shots of van driving over a bridge
2. Filmed interior shots with dialog using shotgun mic. Van was still, crew members rocked vehicle back and forth to make it appear to be moving on the inside. It was bright out, so light hitting the windows is blown out (all you see is white, not static objects in background), but actors are exposed properly. In the few shots where static objects are visible, my editor made them look blown out like the rest.
3. Foley/car ambiance has been recorded separately using a Tascam DR-40 with mics in AB configuration.
4. Dialog, vehicle ambiance, and sound effects are being mixed to appropriate levels in post.
Filming inside a non-moving vehicle worked for me because I liked the blown out look of the windows and had my editor crush the blacks a bit to give it a certain look and feel that is present throughout the movie.I certainly couldn't get away with this for every project though. The method I described would create images that wouldn't fit in, say, a romantic comedy.
