I have this live consert with neal young.
the sound tracks in the movie are 1 dolby digital 5.1 and one PCM 20 bit sound
and one of them has 33 ms delay and the other has -33 ms delay.
I guess maestro will handle the ac3 delay without a problem because you cant move the sound track it will align it by it self, but the pcm part you can move as you like.
so my question is how do I set a audio delay of 33 or -33 for the pcm track in maestro? I dont remember witch track had witch of the delays and I am at work for the moment so I cant look it up but it shouldnt matter should it?
anyway thanks in advance

1ms = 0.001 seconds, so 33ms = 0.033 seconds
In 29.97fps NTSC, 33ms = 0.989 frames
In 23.97fps NTSC, 33ms = 0.791 frames
In 25fps PAL, 33ms = 0.825 frames
In any of the case 33ms is almost 1 frame off. So move your audio from the video just 1 frame. In the movie timeline in Maestro, click on the magnifying glass thingy all the way down to frame level. Then move your audio off 1 frame, that's all. But truely you probably couldn't tell a 33ms delay anyways.
