recording equipments used in filmmaking??


In INDIA most of the time the voices are dubbed later in the studio using a dubbing artist much like an animation movie.
BUT how does it work in hollywood?Has hollywood ever done dubbing ?
I am sure most of the time they do it in real time.but how do they do it?
Is there a video on youtube that explains clearly about Sound recording?

Say if one has to take a scene that involves two characters talking to each other walking in a busy market place full of noise.How to record actors conversation in real time without the noisy background and reproduce it later in editing with all the sound effects?

There is sometimes dubbing in hollywood movies. It is usually not for the entire movie, however, just select scenes or lines. These lines would probably be recorded after principal photography.

There is no simple answer to your question, but I will answer it as simply as I can. There is usually a whole department of a hollywood movie devoted to sound recording.

The microphones used to record most movie audio is called a Shotgun mic. It can record from far away of the source of the sound. They also give you a narrow pickup pattern, so you reduce background noise. These are the mics that you see attached to booms with a fuzzy windguard pointing down at the subject. the pointing of the mic downward also reduces background noise.

So basically, the audio is recorded by the mic and added to the video concurrently in digital video. I can't speak for film video, I guess the mic would record directly to the magnetic strip on film, but I don't know. Sound effects and editing come in later, in post production (after shooting the shot.)

ADR is the norm in Hollywood. Location sound is taken as a guide, mostly. The foley and sound design are combined with ADR. It would be a rare Hollywood film that would use location sound over ADR. It's about the control the director has over the final sound design that makes it attractive.
