Audio out of sync with Premiere Pro

[Akiraro]

Hello,

This is my first post here, I really hope you guys can help me out. I'm currently using Adobe Premiere Pro (7) under Windowns XP SP1. I have 60 mins of video from my Sony Digital8 camcorder. I use Premiere Pro to capture my digital video via Firewire.

Capture setting is set to DV-AVI 720x480, 16 bit, 48khz. The file captured is flawless, it plays perfectly in Windows Media Player, Nero Showtime and ATI media player without any video/audio sync problem. When I use that DV-AVI file (original from the capture) without editing it in Premiere Pro and encode it (Mpeg-2) with TMPGEnc, the audio is perfectly in sync and it plays perfectly on my standalone DVD players (JVC, Pioneer).

The problem:
I want to edit and remove parts of the video that I don't like. At first, I thought that my video/audio was out of sync in Premiere after a couple of trims and edits but I find out that the original DV-AVI file is already out of sync in the monitor of Premiere. The audio/video at the beggining of the clip is synced fine, but by the end of the clip, the video is behind the audio by almost 1 sec. But like I said before, this DV-AVI file from capture plays perfectly in all other applications. If I simply drag this DV-AVI video on the timeline of Premiere Pro and export it out again, the new DV-AVI file is out of sync. I used the exact same setting for the Project: DV-AVI, 720x480, 16 bit, 48khz, NTSC 29.97. How come Premiere Pro can't even handle his own DV-AVI file from capture? What Am'I doing wrong?

My computer
- Pentium 4, 2.66Ghz with 1gram (DDR)
- Windows XP with Service Pack 1

Capture video (Digital 8 Sony TRV120)
- Video: DV-AVI 720x480, NTSC 29.97 fps drop frames timecode
- Audio: 16 bit, 48khz, PCM

Project Setting in Premiere Pro
- Video: DV-AVI 720x480, NTSC 29.97 drop frames timecode
- Audio: 16 bit, 48khz, Uncompressed (PCM)

I just find the solution (thanks to the guys from Adobe forum) and I would like to share it with people that has the same problem.

Some older Digital Camcorders (miniDV, Digital8) are not using 48khz for their 16 bit sound. It looks like mine (Sony Digital8 TRV120) is somewhere between 32khz-44khz or maybe it's not a stable 48khz. When you capture your digital video with Premiere Pro and you specify 48khz for the sound, it looks like that setting is on only for the project setting and the timeline but Premiere will still capture your video/audio in his original form.

I just use Scenalyzer Live 2.1 for the capture and now the DV-AVI works perfectly in the timeline of Premiere Pro. Because with Scenalyzer Live, you can specify the software to capture the audio at a steady 48khz. It will automatically convert your digital audio to 48khz. I just tested my 60 mins video again (edits and trims with Premiere) and the final export output in mpeg2 format and DV-AVI format are now perfectly in sync.

I guess I'll just have to use Scenalyzer Live from now on for the capture and then export it to Premiere for editing.


I'M VERY HAPPY. CHEERS !!!

I have the same issue as you with my audio as 32Khz, but I have dropped frames in the middle of the avi with audio sync problems. is there anyway to fix or get rid of these dropped frames to keep the audio in sync?
