Audio sync issues importing DVDs into Final Cut Pro
I have a problem that happens every now and then:
When I rip a DVD to a QuickTime file and import this QuickTime file into Final Cut Pro, the audio is out of sync and in and out points don’t match on outputs.
This has happened on four different MacPro systems using both MPEG Streamclip and DVDxDV Pro – on both PAL and NTSC DVD discs.
Once I rip the DVD to a QuickTime file, I import into Final Cut. Before doing anything else, I notice the audio is out of sync. When I try to realign the audio, the sync drifts as the video progresses.
Also, if I mark in and out on Final Cut and export this file, then I end up with a completely different in and out point on the rendered file.
Actually, this is a complete mess – everything from audio not syncing to inconsistent renders, etc.
Is there ANY WAY to rip a DVD into Final Cut reliably? These DVDs are NOT copy protected as they’re directors’ reels intended to be ingested into our Final Cut systems and edited.
Thanks for your help.

Scott,
You’re trying the two best apps there are for ripping. Both work properly for me. Are you certain you have all the settings correct?

What are some of the settings you might suspect that I have wrong?
These DVDs are from overseas, so I’ve tried ripping to both PAL and NTSC.

That’s a tough call since I’m not looking at them, but conceivably they may be from film or progressive sources, so the frame rate might be off. That’s just a guess…

Hi Scott,
Please have a look to the MPGStreamclip HELP: Editing the stream.Mac OX 10.5.2-FC 6.02-QT 7.4.1

I read through the MPEG Streamclip User’s Guide, and that didn’t solve any problems.
I did find a work around on my own though: if I export the DVD as a DV file instead of converting it to a QuickTime file, then the audio remains in sync.
One day, I’d like to know if there’s a way to export directly to a QuickTime file as this just adds another step in the process.

Hi Scott,
I think that the thing is very clear. When you set IN and OUT in a MPG, those points are valid for the audio. But for the video not because your working with GOPs, not with independent frames.
If you want to be precise with the video too:“Editing and trimming can be accurate only if In and Out are both on key frames; You can go to keyframes using the up and down arrow keys or the “Go to Keyframe” command in the Edit menu”.
So you need to use the up-down harrow. Where the play-head will park will be an “I” (key) frame where you can set your IN or OUT without getting out of sync.Mac OX 10.5.2-FC 6.02-QT 7.4.1

We’re talking about two different problems.
I’m not setting any out and in points at first – the audio is out-of-sync when I rip the entire DVD to a QuickTime file – before any editing whatsoever.
In my earlier posts – I was just mentioning yet another problem I was encountering with outputting files originally ripped from DVDs: the out and in points on exported files from Final Cut don’t match what the out and in points were on the Final Cut timeline. The audio stays in sync in this case.

Hi Scott,
“These DVDs are NOT copy protected as they’re directors’ reels intended to be ingested into our Final Cut systems and edited”.
MPG2 are not to be edited. Is a format for delivery. To edit use any “Intraframe’ codec.[Scott Ellison] “These DVDs are from overseas, so I’ve tried ripping to both PAL and NTSC.”
The first think you need is to know what kind of stream you are trying to transcode. So bring the VOB to MPGStreamclip and see the “Stream info” (file menu). Then export according with that info. You can not export a NTSC MPG2 as PAL. So first make sure the video standard and field order.
Then if the MPG2 are NTSC you need to know if the stream is “drop frame” or “not drop frame”.
if you export a “DF” stream as “NDF” (or the opposite) you will have the kind of sync problems that you are having now.
If you export as .DV, what you are getting is a DV sequence. The same format used by iMOVIE. Yes, you won’t have sync problems because DV sequences do not use TC, but you are constrained to the DV codec, and always have to be rendered in FC.
if you want to rip a DVD and re-edit with a minimum of quality you need to export it at least as DV50.Mac OX 10.5.2-FC 6.02-QT 7.4.1
