Sound out of syn and need recommendations on programs.

[PsychoPigeon]

Hi,

I have been spending all day to try and convert an avi file to mpeg2 then burn to dvd using Nero. Searching on the internet i found a forum post saying to use DVD Flick, a program that converts then burns. I'm no good with options on these programs I had no idea what to do really so I just went through it and eventually it started to convert then it started burning to the dvd without my permission. Anyway to my suprise it worked, started watching some of the film to make sure it was ok and half way through the sound is 3 seconds out of sync and it continues till the end of the film.

I'm going to attempt to do it again but this time I want to use Nero Express, but to do that I need to convert the avi to mpeg2 ( which I thought Nero had the ability to do ). Anyway recommendations on what program I should use to convert? Should I be converting to mpeg2 or vob?


Thanks in advance.

Your first lesson is to use a program known as gspot .

It is most likely caused by VBR audio ... which most conversion tools screwup with .

Now if VBR audio is discovered , then

Virtualdub > ignore audio vbr detection > save as uncompressed wav
Vitualdub > video to direct stream copy > disable audio > save as new avi

Bring both this new avi and wav into syncview > audio tools > set parameters to stretch to match video length > process .

Re-combine streams back in vitualdub to form a new avi .

I used gspot and VBR audio is highlighted, however i have a bit of a problem.

When I load the avi file into Vdub I get an error message shown here:

Do you know what that means?

It means you need to have the XviD codec on your computer.
But if you already have XviD, then it means you need to find out
why it is not working.

Thanks man, worked like a charm.

Quick question:

It loaded the avi file and gave me a warning message, i'd just like clarificaiton that I should continue to follow BJs' instructions or if I have to do something else:

With VBR, Bjs's method should work fine. If I save out as a WAV, I do that in 'Full Processing' mode or you can end up with a WAV container with the other audio inside. Once you have the WAV, you can either add that with the video into your MPEG encoder, if it accepts separate streams, or mux it back with the video in VD by adding it back and saving both the audio and video as a direct stream copy.

If you need more graphic instructions, this guide by jimmalenko may help. It's for VD Mod, which I find a little easier to use for audio operations, but VD works the same: https://forum.videohelp.com/topic280779.html

Ok, the virtualdub i have is the latest version and some options aren't visable unlike on the pictures shown on that tutorial. What I did was load the avi into VD, then went File>Save WAV, then it saved a wav file of the sound of the avi. I saved the avi as a new avi and opened SyncView. Put both files in there but couldn't find the option you were describing BJ. If anyone has the latest version of SyncView could you lead me to the option BJ is describing? I also need the latest tutorial of puting back together the 2 files in VD.

Thanks a lot.

Here's a VD tutorial for WAV which might be closer to your version of VD. Either one works the same way. Just save out as a WAV with full processing. If you also want just the video with no audio, save that out in 'Direct Stream' by using 'No audio'. https://www.videohelp.com/oldguides/virtualdubaudio

Most times, converting the MP3 VBR to WAV audio is all you need to do when you have VBR audio, and the WAV will work fine for sync when the video and audio are encoded to MPEG-2. Then you wouldn't need SyncView. I haven't used it, so no help there.

If you want to mux (Add) the WAV audio back with the video in VD, load the video, go to 'Audio>Audio from another file..' and add it back in. Save both video and audio as 'Direct stream'.

I use VD Mod most times for all this, as the audio handling methods are easier, IMO.

If you plan do this fairly often, you might look into ConvertXToDVD. It handles most MP3 VBR audio with no problems, also PAL<>NTSC conversions. But it is payware.

Well I followed your instructions and putting the wav and video file into different soucres on my mpeg encoder did help a little bit, it's still out of sync by 1-2 seconds or so. Keep in mind it's only half way through the movie that it goes out of sync, which is strange, the original file doesn't go out of sync at all. It's only when converted.

Merry Christmas.

Not really so unusual. Probably the result of a bad join of two parts at some point. A video player can skip over those minor problems most times. But encoding needs a 100% error free video.

But you may be able to split the video back to the two parts, then change the sync for the two parts individually and rejoin them. I warned you this may not be easy.
