hits that frame.
So, going back to our Scope video. Let's say that at frame
01:00:01:15.13 we have a huge wave crashing over the screen. We think
we have a nice cymbal that approximates that sound (ok, samplers are a
different post.) If we rewind the video tape to, hmm, maybe 10 or 20
seconds before the wave visual, press play on the video tape, and
press record on our sequencer, we're recording in sync. Now, when the
wave crashes, you go BANG on the keyboard (or whatever gear triggers
your cymbal,) and you hear a nice crash, at the exact point where you
see the wave crash over the screen. You wait a few seconds for the
sound to die away, and you stop all the machines.
Now, if you play back the video tape and SLAVE the sequencer to it,
the sounds on the sequencer will play back in EXACTLY the same place
as you recorded. Thus, your cymbal will crash every time you see that
wave crash over the screen, with approximately 1/30 sec accuracy. You
can build up multiple sounds and effects to recreate the entire sound
of the original videotape, using whatever sounds you want. With a
sampler (or an analog deck, for pre-Gen-X'ers,) you can even add your
own dialog this way.
