How do animators sync up their characters talking with audio?

1.13K views

How do they make their character’s mouths move at just the right speed? Is there a lot of overshooting/undershooting and then having to go back and fix the frames? Or is there some general rule of thumb (x amount of frames to each second of audio)?

Back in the analog days they would write a chart of what sounds were being made each 1/24th (or 1/12th) of a second on the soundtrack.

Occasionally they would also film the voice actors while recording, and that can be used as a reference.

Nowadays computers make it easier. When I animate dialogue in TVPaint, I can import the audio file into the timeline, and when I scrub frame-by-frame, the program plays just that frame’s snippet of audio and I can usually tell what sound is being made.
