Strangely audio out of sync

[himmania]

So guys the problem is really big ****. Its came out from nowhere!!! I take 4 old VHS's with animation. And thats the way how i riped -

1 - i capture the vids in MPEG 2 - DVD format.
2 - i make d2v and reencode the wave audio.
3 - i open the .avs file with VdubMod
LoadPlugin("C:\DGDecode.dll")
mpeg2source("C:\DUM.d2v")
Temporalsoften(2,0,50,mode=2)
FluxSmoothST(5,7)
aWarpSharp
crop---
resize <-- thats the filters.
At first there was no problems with anything. i Ripped around 15clips for a few days. But after that theres came oout - out of sync audio without any change of the way of the ripping.
Without any changes settings its start out of sync audio with every each video which i converted. I bought a new mainbord, RAM and processor and there is again out of sync audio. The avs filter are the same like the first videos in which there is not out of sync audio....Why with the same avs. at first there is no out of sync but after 2-3 days there is out of sync.

Edit: In the Mpeg file - there is no out of sync. I just convert now the mpeg only with VdubMod (without avisynth filters) and there is again out of sync.

Please read and follow forum rules. You've broken two with this post: rule 9 (use a proper thread title) and rule 4 (no profanity). Thank you.

I had a similar problem, was using Pinnacle Mp 120 Card and Sware. Updated the sware and captured again and it worked fine for me.

Some on KVCD forum dug this up for me.

What is video PTS jumps in an MPEG file?

One of your new releases said it has this feature fixed: "Video and audio synchronization problem for MPEG files with video PTS jumps. (BUG)" Can you please explain what does it mean? Will it restamp PTS/DTS when I concatenate few MPEG files together?

In many MPEG hardware and software encoders, the system will drop video frames when it cannot keep up with a real time video input. This could be caused by an insufficient CPU/DSP processor power, temporary memory bandwidth shortage, temporary disk access error, system/disk/memory buffer full, or others. When this occurs, the encoder will introduce a PTS time jump to the presentation time of the next image, while keeping the audio continuous which is less likely to have the same problems as those of the video and which is also more noticeable if a sound drop occurred. Those video PTS jumps are encoded in the packet headers as a multiplexed MPEG stream. Also, the PTS time codes may start at any value in an MPEG file. Thus, each MPEG file will be treated as an independent time code base. When two MPEG files are connected together, the editor will make sure to generate a new continuous PTS time code and preserve all PTS jumps within the original 2 MPEG inputs.

Not addressing to anyone but just that PTS jumps in mpeg could be the problem for audio sync.

I tried remuxing the file and it was out of sync but if i cut small clips then its fine.

[himmania]

yeah the same. When i cut small part from the whole video with out of sync then its fine for me too.

Now I just have to find out what is -
sware?
and PTS jumps?
;]

[himmania]

Well i capture the video in avi format (without compression) and after that re-encoded the video and there is again audio out of sync. Do you think thats can be from 320W Case???? cause mainboard, cpu, ram are new.....

What program are you using to capture? ...and why is this in the AVISynth Usage forum?

WInDVR - capture MPEG2
Ulead Video Studio - capture avi

this topic is here because at firts i thought that may be the problem is in the avs script.

Sorry, I am unfamiliar with those programs. Hopefully someone else can give you some clues.

BTW, the comment about where this thread belongs wasn't a commentary on where you originally posted it, I was wondering if it could be moved to another forum that would be more likely to know how to solve your issues.
