Dubbing mbr output to video file

Common scenario: you record a live band audio on mbr and simultaneously record video of the same performance - how do you dub the audio track onto the video and sync it? I have recorded the video as MPEG.
I have used Virtualdub a lot and can import the audio as a wav file, has anyone else got a good method. The ultimate aim it to put it on Youtube so quality is not a premier consideration.

i use video studio 9. the hardest part is getting everything in sync, it takes time and practice.
that said on my older camera it was impossible to sync as the video would slow and speed up. i got a casio exlim digital camera and now that isnt an issue.
also it helps if you trim your audio to fit in advance of importing into video editing software..

Understood. What do you use to trim your audio?
I currently do something like this by finding the time of a particular event on the video and audio track, making them identical and then shuffling the audio to fit. It is laborious.
In an ideal world i would want a clapperboard function, where (for example) a drumbeat or a vocal can be both seen and heard giving one-click sync.

I used to work in TV and getting things to sync was done using SMTPE timecode. This was burned into the video and audio and this kept the two separate sources synchronised.

With an MBR you don't have that luxury, but modern sold state cameras should play back at the same rate as they record and the MBR shouldn't drift too far either.

A simple device like a clapper board would work, but would look sp pretentious on stage, but a simple whack on a snare that the camera saw and the MBR recorded would be a useful marker to sync up your tracks with the video. It could be a good while before you started playing for real and wouldn't need to detract from the live event. You can edit it out for the video.

If you can get your hands on Adobe Premier, it's a professional video editing package, you will be able to do all the things you need and more. It takes a while to get the hang of it and needs quite a bit of disk space and a fair amount of processor power, but it's worth using.

Good luck, it would be great to see some results of your efforts.

Excellent idea.
The band whistle through their numbers so there is no time to set up a new song. I end up with a long wav file (which I can then cut up) and a number of smaller video files.
I need to be able to mark the snare hit on both and then align those markers. Thanks for your suggestion about the snare hit - really helpful.
