Sync audio and video, equipment? I need some help or tips in the area of video and audio sync. Think a music videoclip, where the audio is recorded independently to create a master audio track and then the video will follow along. Not interested at all in the audio recorded with the videocamera.

I'm experienced with the audio part, but have done only one video project of this nature with iMovie (absolute noob and not willing to invest much in video editing software at the moment).  While editing, it was an absolute pain to get everything in sync, lips motion with lyrics, ... I had to do it by hand drag and dropping frames around the audio track. Waste of time.

I was wondering if there's anything I can do while recording either the audio or the video that would easy this process. I do have semi-pro audio equipment with timing signals like SMPTE and things like that but I've never used them, not sure if they would be of any help for this. 

Thanks!
Haha! In movies about movies you always see this clap in the beginning of a shot. The one where the take number and everything is written on with chalk. And they hold it in front of the cam and make one loud clapping noise with it.

Well, if you have ever wondered what this ritual is for, congrats! You have found the problem to the solution ;-))

You get a video frame on which you see the clap closing and at the same time you can see the noise level peeking in the audio recording.

The poor mans version of this is to tell one of your actors to do the clap with her hands.
