hey guys, what's up??

I need some advice in a tricky job i'm in. We'll shoot inside a moving bus, and I want to know if there is some way to capture the voices without the bus noise. (which will be recorded later.) So, which kind of mics and gear do you recommend?

I have never used one, but a noise cancelling microphone like the ones used on helicopters headsets might help.

and if it doesn't work I have this for you. Just recorded a few days back.

Re-record the voices later ie in a studio or other quiet location!

hi, will this technique work? with these type of mics, do you need to "up" your voice a bit to be able to produce/ hear any sound level?

I doubt that it will be practical to use for this kind of application in the short term, but microsoft have done quite a bit of work in isolating individual sound sources in noisy environments with the kinect mic array. It will be interesting to see how this kind of technology develops.

Well, this is how the guys in the big movie studios do it.
Note: they have access to all kinds of mics and gear and sound engineers AND by filming the scenes outside and then getting the actors to re-record the voices in a studio they have to pay for the actors time twice.
So, moral of the story: re-recording in a noise free environment later them mixing to overlay the bus sound is the way to go. :wink:

Since the original question was posted some time ago I don't know if it still helps, but here are my 2 cents:

Having some ambient noise caused by the bus ain't much of a problem, since the audience won't be disturbed by it. Use a hotgun mic like the MKH416 or the Schoeps SuperCMIT (haven't used it, but it seems to work wonders) in order to get a good loud dialogue with only a few background sounds. Try to get some seconds before and after the shot so that you have some material for fading the different shots in the post. You could also try to get rid of the noise by using a multiband expander, but good booming should do 90% of the shot.
Don't rely on ADR (automated dialogue replacement = re-recording the dialogue in the studio) because most actors will have a hard time to actually re-sync their voice and sometimes YOU will have a hard time to explain them why they have to read their text again =/
