Captured files have audio ‘pop’ sounds and out of sync
I have captured some tapes of a hotel conference and have files which are long (45 min). There are intermittent popping sounds on the clips which I can’t hear when I just play the tape itself. Audio and video are in sync at the start of the clip, but then are really out by the end. I have had long clips before and this is the first time this has happened. Any ideas?

I have been experiencing the same thing, except my audio is out-of- sync from the start. I capture with Premiere. I must re-sync the audio on the time-line, usually 5 audio frames to the left of video. Then, just before going to Encore (after saving the edited file to a new sequence)to make a DVD, I have to adjust the audio back to normal then advance 5 frames (indented)to the right of video. This is the ONLY way I can maintain sync. Very frustrating and time consuming as well, but it seems to be the only workaround I can figure out.
Regarding the poping…I too get pops and sometimes a crackle sound on certain soundbites. I solve this problem by going to Audio Effects – Stereo & select De-crackle. Apply to clip & open in Effect Controls. Under Individual Parameters I select Threshold and adjust the slide to about 35%. De-clicker is another option to try. In most cases the ‘snap, crackle and pop’ seems to disappear.
Soundbooth has a ‘pop’ tool as well, but the above method is much faster and doesn’t seem to effect the quality of the audio.
Hope this helps.
