Audio and video not synchronised

[JohnARiley]

As a novice at DVD making I have burned my first DVD using MF4 from a digital TV source (MPEG) The edited file plays back OK but the the audio is not in sync with the video on the disc. Something appears to have gone wrong in the conversion and burning stages. Nothing in User Guide on this topic. Help appreciated.

kindly use the search function.... there have been numerous threads about this kind of problem....

Using the search function won't do any good because, yes there have been numerous threads, but no answers!

Did you go directly to disk or do you have an MPEG-2 file that you imported into MF4? If you have an MPEG-2 file that was imported, an obvious question is if the original exhibits the video/audio sync problem. If you went straight to disk, does this problem occur with everything captured? If so, can you try importing an MPEG-2 file to MF4 to see if you still have the issue? I guess one thing that comes to mind is how your digital TV source is connected to your PC (example, USB connection) and if this is causing the sync issues.

I imported an MPEG-2 file, this saved using a DigiTV PCI card. The saved file plays back perfectly using the DigiTV software and when imported into MF4. The problem arises when the file is processed to create the DVD.

Did you have the option "Do not convert compliant files" ticked?

If you have the "Do not convert compliant files" option checked and you're still having the sync problem, can you try writing the DVD file output to your hard drive to see if we can isolate the sync problem to only when writing to a DVD. If the problem is limited to burning to DVD, you might want to check your IDE channel Advanced Settings to confirm that DMA is used. I use MovieFactory 4 to author and write the resulting files to my hard drive. I then use Nero Recode to compress and burn the files to a single-layer DVD.

MPEG files are not meant to be edited. If your capture device allows capture to AVI format, you'll probably have better results. Movie factory will encode it to MPEG / DVD format after editing.

Editing an MPEG with Movie Factory or Video Studio can corrupt it in a way that causes it to get out of sync later when it is re-multiplexed for the DVD. In my case, I believe it was the transitions between MPEGs, or between scenes in an MPEG file that cause corruption. (The same source MPEG stayed in-sync when I make an unedited DVD.)

MPEG capture is also difficult. It requires lots of CPU power. If your capture device does not have it's own hardware MPEG encoder, you may be getting corruption during capture. Again, this corruption won't generally cause sync problems until the file is de-multiplexed & re-multiplexed.

If you must edit MPEGs, you can try a special-purpose MPEG editor, such as Womble MPEG Video Wizard ($120 after trial period). It's only an editor, so you still need a program (i.e. Movie Factory) for DVD authoring.

I haven't had any sync problems since switching to the Womble editor. I still use Ulead DVD Workshop for authoring DVDs.

And like ploggy said, search the forum for "sync" and you'll find lots of suggestions. This problem seems to have several different causes & solutions.

Ok, according to the "Sticky" at the top of the VS forum:

Digital Video (mini-DV)
Most digital camcorders have a Firewire connector and so can attach directly to a firewire port on the computer.
Capture to Mpeg2 if you have a fast computer (>2.5 GHz, 1GB RAM, disk with > 20 GB of available unfragmented space) because the whole video editing process to DVD burn will be faster and simpler.
If your computer CPU is slower than 2 GHZ, capture to AVI (DV) Type 1 because capturing in Mpeg 2 format puts too great a load on the CPU while capturing video in real-time. DV Type 1 is recommended because users have experienced problems with AVI Type 2.
You can capture directly with Video Studio in the Capture module.

Since the recommended procedures stated to capture to MPEG2 I have been. I have a fast computer with firewire and DV camcorder. Then edit in VS9.
So is the recommended procedures not accurate on this?

Please post that question in the VideoStudio forum since that
is where you read the sticky post.

By appling patch-2 on the MovieFactory 4 the problem look to be solved. Please test it your self again. During my test edited a TV film "Rosemary's Baby" with version 4 this resulted in an "out of sync situation". By editing this film (mpeg-2 recording) with version 4.02 it seems ok! Also after tree commercials cuts.
