This has probably been covered before, but I searched and couldn't find anything.

What is the best way to run external audio to a DVD I'm authoring? I want to add soundboard audio to an audience recorded DVD bootleg. If someone could post a step by step process, or give me a link to something of the sort I would be greatly appreciative. Thanks!

Adding a second audio track shouldn't be difficult IF you can synch it to the video.

It's not really that difficult once you know how to do it. You need to get the video and audio from the DVD into a video editor and import the new track. Then you find a point at the beginning where they match up. Later in the video the new source may drift off a bit simply because it was made on a different recorder than the original. You need to know how to adjust this if so. With a program like Sony Vegas you can easily adjust it in the timeline. Other programs may require you to load the new source into an audio editor and fix the timing difference. Then you can save the new source and use a DVD authoring program that does not re-encode video to combine the new audio with the video.

There are some things to consider though. If your original video is encoded with AC3 audio you'll either have to have an AC3 plug in for your editor to decode it or separate the audio and video to start with and convert your original audio to WAV for your editor to read it. You also need to know the bitrate of your original video. If the bitrate of the video and audio together shouldn't exceed something like 9.8MBps for the sake of compatibility. If you go higher some DVD players can choke while trying to read it and the video and audio will stutter or not play at all. If the original video was not over 8MBps and you want to encode your new audio source to LPCM WAV you should be ok.

What band and show are you working on?

Thanks stantheman.

Yeah, the bitrate is below, so I shouldn't have a problem. What program do you recommend for syncing the audio w/ video? Can I use VideoReDo?

I wanna add livemetallica.com audio to a Metallica DVD I have.

I use Sony Vegas for all my editing. It allows you to stretch or shrink audio visually so you can zoom in to distinct points and match it up exactly. You can import VOB files directly into Vegas but if your audio is AC3 you need Vegas's AC3 plugin to be able to read or write AC3.
