Audio Trailing Video « Videomaker Community Forums

I am just new to transfer of VHS and 8mm camcorder to DVD. On first burn of DVD using Pinnacle Studio 8, the audio is trailing the video -- worse as the DVD continues. At first, everything appears to match but as you get closer to the end of the 60-63 minute DVD the audio can trail video by as much as 1-2 seconds. I have tried four different burns (trying both DVD-R and DVD-RW)but problem always present. However, it does not appear to start in the same place each time.

Any suggestions for this novice would be greatly appreciated.

When viewing the project prior to burn everything is in sync. The problem appears on the DVD after burn. Following Pinnacle suggestions, I am closing all existing programs (including screen savers and Norton) during the render and burn process.

Jim,

Sounds like your problem could be a classic case of your audio sampling rate being different from what your authoring program wants to see.

DV expects an audio sample rate of 48Khz. Audio is often sampled slower. For example, music sourced from CD's has a sample rate of 44.1 Khz. And some camcorders allow the users to set even lower sample rates - 32Khz, etc.

That diference often results in what you're seeing, sound that starts out synced, but gets progressively more "out of sync" over time.

The cure is to open your audio clips and make sure they're ALL up-sampled to 48Kh before you import them onto your DVDs.

There are other compressions problems that can cause the same kind of 'audio slipping" but if I were you, I'd check that out first.

It trips up a LOT of people.

Let us know how things work out.

Bill, thanks for the information. I'll give it a try and keep you posted.

The original capture was under PCM Compression, 16 bit stereo and a Sample Rate of 48 kHz. Could you please give me some more suggestions? Thanks

The next thing I'd do is compare those settings with your capture presets and make sure that THOSE are set to exactly the same settings. I'm suspicious of the PCM compression. I can't remember off hand if there's a difference between DV compression and PCM, or whether the audio standard for DV *is* PCM compression. Since I've never had your problem, I've never investigated it fully, and like everyone else, I tend to dive deeply into only what goes wrong with my workflow - I'm too busy with clients to investigage stuff that isn't broken in my little world! ; )

You said that some clips beep and some don't. That would cause me to compare the ones that do to the one's that don't. Thre MUST be a difference in their settings (or the "track depth" of the clips that are beeping) - or EVERYTHING would be beeping.

If it does turn out that your compression settings between your clips and your project are EXACTLY the same look at how many tracks of audio the beeping clips are using compared to the non-beeping ones.

If you can't find the problem there, there's a dim outside chance that your timeline is confused somehow about what standard the clips are in.

On that distant chance, I'd try creating a new Project file. Double check the settings. Then copy all your assets onto that fresh timeline. Back in version 2.0 I remember I got things messed up so that I needed to do that to fix them.... but that was years ago. It's just a wild guess.

let me know.

Hello Jim, sorry to hear about the audio. I use Pinnacle Studio 8 aswell and am starting to learn that it has bugs. Read all post here for the scoop. I was wondering how long did it take you to burn that dvd of 63 minutes??

Dino-
During one burn, I let the system run all night long. It can take as long as 6-7 hours to render and burn one hour of DVD.

I would not mind it taking so long if the end product was a quality piece. However, when I get people's lips moving and nothing coming over audio for 2-3 seconds, that is disturbing.

Jim,

I have been using Pinnacle Studio Deluxe 7 for about 2 years now. Some have really beat up Pinnacle about this program and I do have some issues with it myself. However, one must remember this is a low end or entry level program. If one tries to use this program from edit to render and it's more than, I'd say, 15 to 20 minutes there will be problems. With that said, I use it to produce a 1 hour local TV show. There is not a week that goes by that I do not have problems from hang ups to sync problems.

I output to VHS with mine, boy there has been some real sync problems with that in itself. But here are some tips that might help:

1)have 2 harddrives...if either of the harddrives exceed 50% of capacity, that will through a wrench into Pinnacle Studio.

2)Defrag often!!!

3)Forget all the transitions!!!

4)Push it to the limits

5)DON"T produce a TV show with it!!!

6)More CPU the better

I learned a lot about how the edit works and how to work around certain problems because they caused Pinnacle such problems. Honestly, I can't beat up Pinnacle Studio. I realize it's limitations.

Hope it helps!

BTW, I ordered Vegas, it show be here soon!!

Changed like Saul,

I had the same problem twice but on vhs outputs direct from the timeline. The first time I had bad sectors on the program disk which later dided and was replaced. The second was when I alowed the record drive to get two full with to meny overrights with out defraging.
