Audio synch off EVERYTIME

bonze10 wrote on 12/15/2003, 6:11 PM
Ok, I've burned 5 discs and EVERY SINGLE ONE the audio is either off half way through and gets worse as it goes, or its off from frame 1.

I have searched this forum, and I've tried everything. My captured MPEG 2 DVD ready video is in perfect synch, but when burned onto a DVD using DVDA, the audio is ALWAYS off. It never fails. It's slightly behind, and like I said, it gets worse as it goes along. I've tried rendering separate video and audio streams in Vegas, and it previews fine in DVDA, but then after the burn, the disc is totally off halfway through or so. WHATS THE PROBLEM?

I'm burning a single play movie onto a DVD+R. It's about an hour and a half long. I've had DVDA recompress the video to fit it onto one disc, and I've even re-rendered the captured video in Vegas, and as I've mentioned, I've even done the separate streams, a DVDA video MPEG2 stream, and a AC-3 audio stream, and preview is perfect, but the final burn is ALWAYS OFF.

Anyone know how the hell to get around this. It's really burning me up. I hate to switch to a new product, but at this point, it looks like my only option unless someone has the answer.

Why would you switch to a different problem if you don't even know what is causing the problem?

What type of footage are we talking about here? Where did it come from? How was it captured straight to MPEG2 DVD?

When you rendered in Vegas, how did you render the files?

When you make the disc what are you playing it back in that it falls out of synch? A TV-top DVD or your PC? Have you tried any other DVD Player? It may be the hardware you are working with...

Tons of questions - not to be unanswered before placing blame on DVDA.

Its captured thru my all in wonder 128 straight to mpeg 2 dvd. I optimize it to fit on one disc. Audio off.

And naturally, when I render in vegas, I used both the mpeg 2 dvd setting, as well as separate DVDA mpeg2 video stream, and AC-3 audio streams. Again, audio off in final disc.

And I've played it on 4 different sets, 2 computers, 2 dvd players. Off everytime. Never fails.

I have made DVD's from home video in the past using the exact same setup with no problems whatsoever. But this just wont work. It seems the longer the video, the more the audio is off cuz it gets worse as the video progresses. And by the end, its soooo off, dialogue will be completed before the audio is even heard.

Any suggestions???

If the preview in DVDA is fine, then the project is fine. If the sound is off on a variety of playback devices, then the lose of sync is actually on the disc. Have you tried burning with another device? DGrob

What if you try this: Capture as DV-AVI, allow Vegas to render the video and audio, and then see if it is in sync. This is the recommended method.

Jetdv offers a practical solution. I've had the synch problem too, when rendering a long show with, let's say, 200 audio and video edits directly to MPEG. After wasting a lot of time (1.2 ghz renders ever so slowly) and pxxxxxg off my son I tried Tools-render to a new track then encoded the new track. Problem solved. Later I read the solution on this forum and cursed myself for not checking here first. BTW: the Main Concept coec version 1.4 running on a Wal-Mart "Xtreme" 2.6 ghz with 512 RAM renders at 0.75:1, as opposed to the 2.5:1 I get with this one.

This, I'm sure would work, as that is how most of my home video wuz done with no problems. HOWEVER this video is on a VHS and I have no way of capturing it to DV. I could try capturing it to a DV tape on my camcorder first, BUT that has caused problems in the past. The video would drop frames on the DV tape from the analog source for some odd reason so I couldn't do it that way.

I guess my next thing to try, is just rendering the entire captured MPEG file as one DV-AVI file and trying it in DVDA and see what happens.

And as for trying to record using another device, how many of us have more than one device?? ;) I'm sure some of you do, but I have no need for more than one DVD recording drive so thats not an option.

I wuz just hoping that this wuz a problem alot of people had, and that there would be a fairly easy solution but guess I'm SOL on that hope eh? hehe.

I capture analog digitally all the time. Just connect the VHS VCR to my deck and my deck to the computer. Most cameras today will do the same thing as will external convertors. If your camera can record the VHS onto MiniDV, there's a GOOD chance it can also passthru the signal over firewire eliminating the need for the MiniDV tape and allowing you to capture as a DV-AVI file.

I've thought of that, but never tried it cuz when vegas capture captures from the camera, it plays the tape. If there's no tape to play, will it still work??

Update : I just tried it, and it didn't work. Vegas capture expects a tape. So how do I get it captured this way? I got the VCR hooked up to the "in" video ports on the camera, and the cam hooked up to the firewire. The video shows on the camera's LCD screen, but vegas won't accept it. Just sez "please insert a tape" so I did, but it still wants to play the tape. It won't just take the video stream. So how is this done?

In the capture program, go to Options - Preferences and uncheck "Enable DV Device Control". Then it will work with no tape.

Ok, I did that, and can see how it would work that way, but apparently my camera doesn't support the "pass-thru" option. All I got wuz a black screen. It's an earlier model sharp mini-dv, so I'm pretty sure that's why it doesn't work. Looks like I'm back to the drawing board, but thanx for all the suggestions!
