I’m in the same exact boat. Have about 70 clips and the first 25 or so audio is all jumbled.
Just recently switched over to Premiere after using Final Cut 7.
What I’m using
Footage shot from a GH2
File type is .mts
Premiere Pro CS6
Macbook Pro 2.6GHz i7 with 16gb ram (OS X 10.8.2)
Does anyone have a solution for this?
