I'm using vg20 and a VG10 for interviews. I bought a Tascam DR-40 to get a better quality (less affected by ambient noise) audio track. I'm using Premiere Pro CS5.5. I can synchronize the files accurately from a sighted clap but by the end of the interview (say 40 minutes) there's a lag between the video and the DR-40 even though all was well to begin with. I'm importing four .mts files directly to the timeline. Is it possible they are not entirely seamlessly joined and that the lag is due to small discontinuities in assembling the clips? Is there a way to turn the four clips into a continuous clip prior to bringing them in to Premiere. I know PMB won't look at the files once they're on the hard drive (mildly annoying). Hope someone can help because what I'm getting is otherwise starting to look pretty good (IMHO).
