Another post about sync problems
There are many, many posts out there about sync problems in PP. Here’s another one: My sound is out of sync after import. Can anyone help?
All the solutions I’ve read come back to the same thing: Re-capture the footage using this, this and that. What if your budget is flat and you can’t afford to rent a deck? Is the only other option doing it by ear?
The footage was shot on DVCPRO50 and the mixer went right into the camera.
Here’s what Gspot says about the file, in case it matters:
Stream Type and A/V Interleave: Type “AVI” – IMPR “n.s.” – I/L “not supported”
Video Codec: 4CC “dv50” – Name “Matrox DVCPRO50 codec”
Video Bitrate “46045 k” – FPS “23.98” – Qf “5.556 bits/pixel”
Audio Codec: Name “PCM Audio”
Audio bitrate “1536kb/s (768ch, stereo)” – Fs “48000 Hz”
I know what some of this means. What I can’t figure out is if any of it matters.
And how can I tell if frames were dropped during capture? The monitor in PP doesn’t appear to skip any (…22-23-00-01-02…). The video and audio timelines are identical in size.
Any help is appreciated.
Warmest regards,

Looks like you shot your footage @ 24fps. What are your project settings?

On starting the project, I select the Panasonic Widescreen 48kHz preset. And then, well, that’s it. I import. Under Project Settings > General, I get this:
Editing mode: DV Playback
Timebase: 23.976 frames/second
Pixel AR: I change this to NTSC Widescreen 16:9
Fields: Progressive
Display format: 24 fps timecode
Audio sample rate: 48000Any thoughts?

Hmm…the project settings do seem to match the media settings. Can you import the video into a new project to see if that helps?

Yes, I’ve tried that several times. Luckily, the offset appears to be consistent ovder the entire file. So pushing the video ahead by 20 frames solves it. The frustration lies in simply not knowing how it happened. I don’t like loose ends.
Thanks for looking at this though.

Were any frames dropped during capture? If NOT then can you send me a short sample of the clip. Email address is in the signature. You can use https://www.yousendit.com to send me the problematic area.

The problematic area is every single captured file (5 hours of DVCPRO50 captured over 10 large files.) The sound is simply 20 frames late. Easily solved, by nudging it over. Just wish I knew why. If the problem recurs after I render or export out of PPro, I’ll definitely take you up on your gracious offer.
Incidentally, I didn’t capture the footage myself, so I don’t know what the guy did. Is there any way of telling if frames were dropped, after the fact?
Thanks again
