sound effects

[jomc]

In films there are two different types of sound - sound that is part of the action onscreen, and other sounds (such as voice-overs). What are the technical terms for these?

In most films everything is done as a voice over. the actors say their lines on set but then in the dubbing procees the com into a studio and read their lines again whilst watching the action. It's all very painstaking but whist filming, you can't get the mics close enough to get a good quality sound. It's then up to an editor to sync up the re-enacted voice parts to the picture. Anyway a voice over is called just that, and a sound effect id called likewise. Written down they are v/o and fx

Non - speech over dubs ie. footsteps or creaking door hinges are done by people called foley artists. i don't know what it means or where it comes from but that's the name they have in Hollywood
