shifting audio keyframes in premiere pro

[flextone]

Hi, I have edited around 1hrs length of footage and then mixed about 7 layers of surround sound mix using the audio mixer in premiere. However now i need to cut this down to 45mins, is there a way of doing this without mixing the surround effects again, i.e. sync the audio mixing "e.g. fade from left to right track", as otherwise I would have to go through each audio track after editing and redo it all!

thanks for any help

I apologize for the delay in responding, and thank you for posting. In Premiere Pro, keyframes written to clips move with the clips when you trim or ripple delete, so much of your mix survives the cut-down; track keyframes stay at fixed points on the timeline, so those passes need checking after each edit. For future projects, lock picture before the final mix, or mix in nested sequences or submixes so later cuts don't break your automation. Adobe's help pages on the Audio Track Mixer explain the automation modes for current versions. I hope you didn't have to redo it all!
