Audio Outta Sync

[gurmukh]

Hi

I have downloaded a dvd rip of Collateral Damage and its proving to be a bit messy when trying to convert to mpg using tmpgenc

I have stripped the audio using VDub and in tmpgenc entered the AVI int he video field and the WAV in the audio field. Encoded as normal, wen i go to view the mpgs, the sound is HEAVILY outta sync.

I open VDub, and using fast processing mode for video, I produce another avi with sound, and this file has sync problems, but the original AVI does not.

Wen i initially load up the original file into VDub, i get an error about the audio being VBR.

Here are the stats for the AVI
Audio - MPEG Layer-3,143 kBit/s, 48,000 Hz, Stereo
Video - 576 x 304, 24 Bits, 156890 Frames, 23.976 Frames/Sec, 108 KB/Sec, DIVXMPG4 V3

576 x 304 23.976fps


I have also run the check in VDub for any unreadable frames but there didnt seem to be a problem.
How can I fix this?

thanks

Did you set your audio output for 44,100 if its VCD?

[gurmukh]

yes
i set it to 44,100 and DIDNT select high quality

I extracted it as a seperate WAV file

But i think the wrong film time is shown when previewing it in windows media player, it shows the film as 1 hour 49 minutes, i only think its about 1 hour 30?

if thats any help on how to fix this divx

2 suggestions :

First try DivFix
http://www.divx-digest.com/software/divfix.html

or
Download this version of Virtualdub (scroll down to "mp3_freeze" version)to check for bad frames:

when you go to audio in vdub set it in full processing mode. then go to conversions check high quality, 44.1 hz, 16 bit and stereo. then go to compression and make sure that it is checked pcm no compression. then go to file menu and save as wav. use this wave as your audio source. probllem solved

I've treid the DIVXFIX, it couldnt find no errors.

The mp3 freeze version of vdub is now going throught he frames, it didnt however inform me about the vbr audio in the avi tho. The other version of vdub did.

I have tried extracing the audio and adding it in tmpgenc, it doesnt work, it all seems HEAVILY out of sync.

Hi

I've had the same problem but i think i solved it.If you are trying to encode an avi file with vbr sound this will cause this.i tried all of the above but i find if i use an audio encoder called tooLame it solves all the problems with sound sync.Just put the tooLame file anywhere on your hard drive then open TmpEnc and go to Environmental settings/External Tools and then in External Audio encoder tick the box Layer 2.Then browse for the file and then encode.I usually encode video separately from audio and then multiplex them after
Note if you using DvD MovieFactory to burn the VCD/SVCd then there is a patch at uleads web site to correct sync problems

Good Luck

how can u multiplex the audio and mpeg to one file?

[wee haggis]

In TMPGE set it to convert video only then .....use TMPGE to do audio only by loading the WAV then convert it to MP2.
You can then use TMPGE to multiplex the parts.

[Spanishfly]

To multiplex open Tmpgenc
Then go under file/mpeg tools.
Now choose Simple multiplex.
Open the video under video input.
Open audio under audio input.
Make sure type is selected as: MPEG-1 Video-CD (non-standard)
Label your output.
There you Go!

you can easily prove to yourself that my way works. use the audio settings i gave you and then save the entire file (video direct stream and audio full processed) as a new avi with virtual dub. then open the new avi and virtual dub will no longer give you the error message on the new file or will say audio is off by 0 ms.

Heya

Secret Agent - ur fix doesnt seem to work, the avi file is now about 1.5 gig, and wen i reopen it in virtualdub, there are no warnings, however wen i begin to encode, the audio is once again out of sync - i have done this by stripping a seperate wav and the avi music.

I am now trying the toolame thing, hopefully that may work?

UPDATE: toolame didnt work either, any other ideas?

UPDATE 2 : The video file is 1 hour 49 mins
The wav file is 108mins, its about a minute longer or so, its not exact. I stripped the audio from vdub.

Should i try converting them seperatly?
