This baffels me to no end. I get my 3 or 4 minute video just the way I want it, transitions, music, stills, etc. I then need to adjust the white balance and apply to all, then I adjust the lightness or darkness and apply to all and without failure the voice gets out of sync with the video. I have tried doing this one scene at a time and it still happens. It does not always happen if I adjust just the white balance, but always happens if I then adjust something else in edit. This just makes no sense to me ?!. Is this a workflow issue, ie do you need to adjust whitebalance and other issues before begining to split, cut intsert etc.? Or is my copy of PD9 corrupted again?

Thanks
