I had a few quick questions about ADR if anyone has the time to help answer them.
I've never done ADR myself, but I find the concept interesting. I saw a clip on YouTube somewhere the actor is fed the original recorded sound, but with a series of metronome clicks before their next line to serve as their cue. Is this true throughout most ADR?
In terms of lining the audio up, do major film productions use automatic software for lineup or are they manually adjusted? I've been looking at 'Vocalign', a plugin for most major DAW's, it seems to do a pretty amazing job from the examples I've seen. Does the operator not listen to the original sound whilst recording, but just the live sound being recorded sound along with the video to see if they match roughly? Or do they listen to both the original and live sound being recorded to try and ascertain how much difference there is between them?
Also, how long is it expected for ADR to take? For instance, a minute long sequence full of dialogue, is it a lengthy process? I don't necessarily mean with all the post effects, I mean just a clean vocal record, aligned to match the original sound.
My last question is really the percentage of audio being replaced. Whilst I understand that either most or all the audio is replaced in post, is this really the case, even for extreme vocal work? By extreme vocal work I mean, an actors voice and tone slightly distorting due to emotion, either through extreme anger or upset. The reason I ask is that I've been paying a bit more attention to the ADR work in recent films, and I find it incredible the actors/actresses are able to reproduce that kind of emotion in their voice, in a sound booth or recording studio. But maybe I'm just underestimating their talent..
Any information is appreciated.
