I have a scene where we had to ADR the actors for their dialogue in a car. What was crucial was that the scene involved the car going faster and faster and the passenger talking louder and louder. Wish there was a way I could keep the car sounds (at least the engine or progression of the speed of the car) intact without the dialogue. So when we do ADR, I would also have a clean "car track".
If I would sit in a pre-production meeting with a similar scene in the future, what would be good advice to tell them on where to rig extra mics? (that won't capture dialogue). I'm assuming this would be taped on the exterior or something?
I'm not saying I wouldn't layer the tracks with sound fx, but it still a good track to build on even if we were to ADR.
(I am a post engineer and have basic knowledge of production audio.)
Thanks a bunch.
