Is there a time code generated on the home
video cameras? How would I sync a recording
of our band doing cover tunes with a home
video of the band playing?
 
Make a clapper. You know, the zebra looking thing they clap at the beginning of takes. When the clapper is closed, the SCHWAK occurs. Now adjust your audio and visual until this one part is sync'd, and you're set.
 
Use two blocks of wood. Don't bother building the damn thing.

I want to take the video, and prerecorded
music I have and dub the music in only certain places where I can make the music match the video. Sort of mili vanilli style
you know lip synching like zz top at the superbowl. I have no clue to what you are talking about. What zebra bars?
 
Aaaaah.

You want to take two different takes of the same song--one recorded on audio, one recorded on video's audio. Sounds easy.

But you're screwed (sorry). Without, say, Adobe Premier or Final Cut Pro (where each frame of video is sync'd with the corresponding music), you'll spend months getting the final mix right. I would suggest getting a "video buddy," who can solve such problems far easier than us audio SOBs.

I don't care if you're Neil Peart--two different recordings will inherently be different in both tempo and pitch, and while pitch doesn't concern us right now, the tempo does. You'll need to stretch certain parts of the song to sync it there, and then pinch other parts to sync it later. With the video suites, this is MUCH easier, so...

Get a video buddy!
 
I don't have much cofidense in my video skills but...

You could try re-doing the video and tyring to play along with the prerecorded music. Then the timing would be almost exactly the same, and where it wasn't, you could copy other music videos, and have the band jumping around in the garden or somthing to fill time.

The only form of time code on any home video/prosumer level would be the Sony's mini DV. But this is not TRUE time code. Affording cameras with time code and VTR (a fancy vcr) to read time code is pricey. Take the best of the two songs and match the video to it. This will be so much easier than to cut the two songs together. Yes, recut the video. Easier to trick the eyes. The only way to match up lip sinc is with time code if you want to be perfect. Are you using analog or digital editing? Which software, if digital? You need to be able to handle accurracy to the frame (1/30 of a second). This is where some form of time code comes in very handy. You are looking for a lengthy edit session, especially if you are doing analog. If I can help more, let me know.

My suggestion would be that the next time you gig, hook up the camera video in to your aux out of your mixer and capture that live sound. Trying to use studio recorded music with a live setting video would seem to fake to me. One other suggestion I can give is that Sonic Foundry makes some software for this type of thing. Don't know much about it. Have seen it in a brouchure but never read about it because it was not something I was interested in.
 
i do this sort of thing in one of my studios. basically, all the tapes used for a music video are inserted in to the machines, and the timecode is read. this is synced with the music straight away. with home video camera, yes, you may experience tempo changes, if you try shooting on digital, it may help issues as it's very good for stability on tape speed. i own cameras aswell, but they're all pro ones, so therefor have a special "timecode out" bnc socket.

this is what id do though...

go to the locatin which you want to record this video. now you'll need to get a clapper board, or as someone mentioned, to blocks of wood. the only thing you can do is this..

hit record, hold the clapper or the blocks of wood infront of the camera, as soon as you hit them together, someone needs to start the music, maybe on a pa system, or if on a budget, a hi fi. the music has to be started on the second the blocks hit each other.

then, when recording all your scenes, do exactly the same.

when it comes to editing, in say adobe premiere, load ALL your video sequences in to adobe. double click them to open the new dialog box up, now locate the section where the blocks hit togeether, and use the frame button to be exact. as soon as the blocks hit each other, click MARK IN. adobe will now cut everything that hapened before this clap from the blocks. now do the same with ALL your videos in the arrangement window.

now, delete all the audio files that go with the videos, or mute them, (right click). you will now just need to move this one piece of audio to just after the "clap", and a little experimentation and trial and error will have to work here to get the lip sync. but once you find the exact frame for the audio to start, there should be no loss in sync.use the scrub feature and make sure in the preview options, the audio is selected.

unfortunately, all our video engineers here at the studio are all busy.

hope this helps.
