Audio waveform gets out of sync
« on: November 29, 2020, 01:34:45 AM »
I'm playing around with "Close Encounters of the Third Kind." And when working placing effects, if I start zooming in to match start/end to waveform, at some zooms the effect matches the waveform perfectly, but if I keep zooming in it looks completely out of sync. I have tried different views of Bass, Alto, Nonvocal etc but they all fall apart when at close zoom. What am I doing wrong?

Is your music variable bit rate or fixes but rate?

Fixed rate solved the problem. Thanks so much. I would have never thought of it!

That seems surprising as one of the first things xlights does when the audio loads is convert it to fixed rate pcm data.

I know from experience. I had a sequence a while back doing the same thing and it was variable bit rate. Re did it in fixed and all was fine.
