AIW 128 PRO Audio Sync problem

[DeanS]

I've searched the forums and I can't seem to find a solution to the audio sync problem that I'm having. Here's the situation and sys specs:

AIW 128 pro AGP w/32 Meg
Asus mobo A7v133
900 Mhz
512M ram
30 G ATA 100 7200 harddive
Win2K SP2
MMC7.1
DVD 4.1
Driver 5.13.1.192
DX8

I'm trying to convert my home videos (HI8 and 8mm video) to SVCD. I capture at 2.1m mpeg2 480x480 non-interleaved and video masking on. The capture mpeg2 appears to play back w/o any audio sync problems. I demux and remux in tmpgen to put it into SVCD compliant form and it's progressively out-of-sync starting within 3 minutes. I've tried capturing to AVI and have the same problem. Does anyone have a suggestion? Any help would be greatly appreciated. Thanks!

Hi,
I have the same problem with almose the same config (I have the Radeon)

It seems that when you loose some frame in capturing the video, the audio continue (u do not loose audio)

there for, these is audio that is bigger in time than the video.

My configuration is not able to capture video in PAL 480*576 without loosing frames.

I am trying to encode the Audio in Wav, ans path it through VirtualDub with sinc to audio activate to see whats happens ...

If someone has a solution for this, I would be glad to know ...

For information : When I read the file I captured with file player, I have no audio out of sync.

It is when I Mux the whole that I have a problem ...

Thx

I'm going to scrub the system down and reload the OS and other software from scratch. I will let you know how that works. Have you been able to get Virtual Dub to work on your system without it dropping frames? Mine shows less than 30% of the CPU is being used but it still drops 20% of the frames. When I used the MMC, I can capture AVI without frame drops.
