nudge audio?

[Mike Kujbida]

If your cursor is moving that much, you need to zoom in on your timeline quite a bit.
The other thing to do is to temporarily disable “Quantize to Frames” which is found under the Options menu (very first item).
If you don’t do this, your audio will only move in 1 frame increments.
Disabling this allows you to move it at the sample level.
Remember to enable it afterwards and make sure not to nudge a video event.

Make sure “Num Lock” is on.

Thanks, Yeah, I didn’t have the Num Lock key on.

Now it’s working but when I press the 1 or the 3 it nudges the track way too much. The 4 and the 6 nudges a little less but I need it to nudge just a teeny, tiny, little bit, like individual samples.

I’m trying to sync a music track to a video of myself playing all the instruments in the song. The music is pre-recorded so I’m just miming each performance along with the playback.

I have a splitter cable coming out of my mp3 player with one side going into the camera and the other side I use for monitoring thru my stereo.

I can line up all the camera audio tracks really well by zooming in on the waves in Sony Vegas. They are close enough that when I play them back I hear no phasing issues.

But when I import the “original” mp3 file that I intend to use for the master audio it looks slightly different than the waves recorded by the camera so I’m having a hard time aligning it tight enough with the final video.

If one wave is slightly ahead or behind the other then they phase or sound like a flanger. I need to be able to nudge the master audio track ever so slightly forward and backward until I get it as close as I can with as little phasing or flanging as possible then I will know it is synced with the others. I plan on muting all the camera tracks when rendering so only the original master is playing.

At first I thought that because my camera records audio ACC at 48khz and the master file that I’m importing into Vegas is an mp3 at 44.1khz that might have something to do with it but they both play back together at the same pitch and tempo so I don’t think that has anything to do with it.

How do y’all sync a music performance with pre-recorded audio?

Thanks

As I said earlier, make sure “Quantize to Frames” is disabled.
Forget about using the 1 and 3 keys to nudge your audio.
Instead, zoom in, place your cursor on the timeline anywhere to select it and manually slide the audio timeline back and forth to get things properly lined up.
I find that it helps to select a short section of the timeline, loop it, press play and then slide the timeline back and forth until you get things properly lined up.
You’ll be able to hear immediately when you have things properly lined up.

I’ve tried everything and still can’t get it to work.

If I sync it at the start of the song then the end is out, if I sync it at the end then the start is out.

Again, I have no problem syncing all the tracks that were recorded with the camera.

But I can’t get the imported 44.1 mp3 to sync. Apparently they are different lengths. I’m going to have to experiment with sample rate converting.

If you have some software like Soundforge, then convert the MP3 to a WAV PCM file with the same sample rate as the other audio (maybe 48k?).

If it’s a long music track, then you might have to stretch it slightly to fit. Get the beginning lined up exactly, then Ctrl-drag the end to align the end exactly. Vegas will stretch/resample the audio and everything should line up nicely.
