how to record overdubs (music lessons)? video on video
 

I typically shoot short guitar lessons, and I need the ability to then have different clips on the final video, where i play for instance the chords of a song on the main one, and on a separate clip the solo which appears just for the duration of the solo and so on..

now,,, I need to be able to record the solos using the previous video as a reference for timing: how can I make sure I record the new clip in sync with the previous one, so that when I make the video-in-video, everything is synced?

before you say so, I cannot use a metronome so I really just need to do what in audio recording would be an overdub, so recording a new instrument while listening to the previous one on the headphones....
again, it's not multi-camera, but different clips that need to be recorded in synch with one another.

or is there an easier way for doing this? I see a lot of people who manage to do it...
thanks

Why not just play back the vegas timeline listening to headphones while recording?

If your audio interface is a multi in/out one, then you can use most editing software in the way you'd use Cubase or Logic, but in practice, you still end up sliding the tracks around because even though the audio latency is not too bad, the video latency seems the key.

I find it much simpler to record the audio to a music sequencer, and produce the tracks in the usual audio way, but just run the camera, and do the sync for the video afterwards - much, much simpler. I just do a clap, or a string pat or flap a pad on the sax as the sync.

yes I guess that's right Edward. I cannot think of another way

I just wanted to avoid being close the computer (for monitoring) while shooting the new clips as it's a bit awkward with mics and stuff.

maybe I should extract only the audio from the main clip, and then record the new clips listening to the audio on an ipod
