Please help! Syncing audio video

[Danrv]

Hi
I'm trying to put together a band demo DVD.I have good vid footage done
on a Canon MD101 MiniDV and the audio is seperate on a Sony Minidisc.
I'm having problems syncing the Sony Minidisc audio (WAV) to the Video track
using my Nero suite.You can drag the audio track to different positions
but I need more precise control.
Would I need pro Video/DVD software to do this?
I've used the free Virtualdub tool but it wouldn't open my AVI clips.
Any help would be much appreciated.

If you can live with messing around with text files, have a look at AVISynth.

Basically, you'd write a text file something like this...

video=AVISource("yourvideo")
audio=WAVSource("youraudio")
delayaudio(audio,-0.5)
audiodub(video,audio)

... and save it as newfile.avs

You can then double click it to listen to it. You can delay the audio in either direction (if you need a 'negative' delay on the audio, it will insert black video frames). To avoid this, you can 'trim' the video first like so:-

video=AVISource("yourvideo")
audio=WAVSource("youraudio")
video=trim(video,100,0)
audiodub(video,audio)

(where 100 is 100 'frames' - substitute any suitable number)

Once you are happy with it, you should be able to encode and burn the resulting avs file using any standard tools.

Slight chance you could do it with video-redo not free but free full working trial One you can run your stuff through its quickstream fix and it might just fix it automatically its quite good at that also you can manually adjust the sync by milliseconds back or fore

no idea if Nero does this, but I usually zoom into the timeframe. that way you can move the audio to match lip synch etc.

Download Sony Vegas Movie Studio and try there. You can generally
precisely move the audio to match video
To do it accurately, you generally have a cue ( audio like a clap) which is on the audio track of the video. once you accurately made it coincide with same cue on the separately recorded audio track , you can then mute the one on the video
another method is to use a separate MiniDV camcorder with an external mic to record ( and use only its audio) and let the recording happen simultaneously then use timecode to match them up

Thanks for the replies.Very helpful.
I'm able to zoom into the timeline in Nero as Toadoftoadhall suggests for
precise audio track adjustment.The '- & +' buttons are right there at the start
of the timeline! Just didn't figure it.
Should be able to sort it now.
