Editing Audio Tracks from DVD - Help!

[shane2943]

Hi everyone!

Here's the run down: I've got a DVD to play this Sunday fo the 4th of July concert. The audio track is a stereo split track with a metrenome click on the left channel and music to accompany the video on the right channel. Now here's what the problem is: I need the metrenome click track on both L/R channels. I need the music gone.

So, I need a way to remove the music track from the audio and then either mono or stereo the click to both L/R channels.

I have access to Windows, Mac OS X and Linux machines. I have tried several different video editors and none of them let me edit the audio! I also have access to a Pro Tools 8 machine but haven't had any training on it.

Short of using Y-cables and splitters on the output of the computers, I've exhausted what my brain can come up with.

HELP! (please )

Can't you just play the DVD from a DVD player, send only the Left to a mono input on the mixer and be done?
Just asking.

Elsewise, what software do you have available on the Mac?

[shane2943]

No plain DVD player available. Also, I should add, that since the output needs to go to projectors and such, the video is VGA. Not many DVD players that I know of have VGA outputs. The worship software that we use for songs, videos, powerpoint, etc, is Easyworship. Also, I should add, that there's more than one DVD that needs to be played for the concert. There's 3 total and each one has it's own audio demand. I only mentioned one in the OP to try and keep the topic simple and straight forward, plus, I figured if someone could instruct me on how to edit that one DVD, I could edit the other 2 as well.

Since there's 3 DVDs, and each one has a different audio track challenge, there'd be a lot of cable switching going on back in the booth.

Far as software on the Mac, since it is my personal computer, I just have what came with OS 10.6 (garage band, iMovie, etc.).

Thank you for the reply, sir!

IF the DVD's have separated VOB and audio folders, you "should" be able to drag/drop the audio from the DVD to your desktop.
From there, (though I'm going from memory since I don't have a DVD to play with) drop the audio track into a Garage Band project on a Basic Track.
You should be able to use the PAN to have only the channel you wish.
From there, Export to Disk as an AIFF or WAVE as a MONO file, and it may even give you the option to choose which channel to export.
The VOB file (video) should drop into iMovie where you can then re-sync the mono audio to it.

The VOB files inthe video_ts directory have a sound track. But I've not ever checked to see if they are stereo.

How is the sound getting from the Mac to the sound board? If you're running L/R into two seperate channels, then the sound board operator can fix it on the fly.

And, if you RIP the DVD track to a computer, then use VLC for playback, you may be able to manipulate your audio output options via VLC's controls.

[shane2943]

The computer that will be playing the videos is a Windows 7 based PC running Easyworship. Ripping the dvd is a definite must anyway since I've had much trouble with Easyworship's DVD playback abilites in the past (plus there's multiple discs and switching them out and then choosing the correct video/audio titlesets and such on. The fly is about impossible). We usually use Dvdfab to rip/transcode the movie straight into a wmv file with the correct audio track already inserted and then add that to the Easyworship schedule. Dvdfab can do a direct rip of the disc, a direct rip of just the video/audio title track I want or it can also rip and then transcode it into wmv, mpeg, avi, etc.

I tried editing the audio in garage band but I probably wasn't doing something right because I couldn't edit the audio track at all. Correct me if I'm wrong, but doesn't garage band only work with limited file types? MP4 being one of them?

What about ProTools? We have a Pro Tools 8 machine that can supposedly edit video as well as audio. I'm sure Protools would be able to edit these tracks I just haven't ever used that monster of a program before.

As far as switch channels at the board, the way our audio is setup in the M7CL board is...complicated. Our audio guy knows why things are set up the way they are, but right now, if I leave the audio tracks alone, there will have to be cable switching during the concert anyway. Has something to do with how the channels are directed to the Avioms or something. He knows way better than I do.

Thank you for the continued help!

You could download Windows Live Movie Maker 2011 onto your Win 7 machine and try it from there.

If you just grab the VOB files out of the Video_TS directory and rename them to MPG, that may give you other options.

I'm don't know iMovie at all and not real familiar with WLMM, so I'm just throwing ideas out there.

[shane2943]

Yeah, tried WLMM and it's pretty basic. A little too basic. I couldn't figure out how to edit audio tracks with it anyway.

I really don't want to do it this way, but what about ripping the DVD, then using a video editor to remove the audio track from the video, then using Audacity to do the audio editing to the track, and then remuxing the audio/video back together somehow?

OY! I thought this would be easy at first. LOL! Nothing ever is.

You can write appropriate presets on the M7 that change routing. You can even simply mute the non-click channel if the Avioms are post-mute.

Hmm...I'll relay this to our head audio tech (I'm just the apprentice tech ).
