So in some behind the scenes video i see the actors acting and the boom operator doing his job and the director will tell the actors during the shot when to look in certain directions or react at a certain time. My question is since the audio for the scene is also being recorded you would hear the director yelling when you sync up the audio so how are you supposed to get clean sound when you need to direct the actors during the scene? My only assumption would be the sounds in the scene would have to be done using ADR?
