| To answer the 2nd part of the question, the actor comes to the ADR stage and watches the film on the screen. They listen to their original performance and then, watching the screen and using the beep-beep-beep to cue them, perform the line (s) again (and again, and again). Once all the lines are recorded, the ADR editor does some fine editing to put it in perfect sync with the original. The dialog editor will provide "fill" to match the scene so that the production ambience doesn't disappear when the ADR comes in.During the final mix, the decision will be made by the director whether to use the ADR or to live with the noisier production that may have a better performance quality. Often it's a combo- sometimes individual words or even syllables will be combined to make the best result.
Good ADR is indistinguishable to the production dialog; when people say "I hate ADR, I can always tell" most of the time they're hearing the one of two lines that never quite worked, and never noticed the 300 other ones that did. It's an art that depends on a great performance, great ADR recording, great ADR editing, and finally great re-recording mixing to make it seamless.
Hope this helps! |
