i'm converting vobs to wmv, and trying to keep the 5.1 sound.

my success has been limited, and dissaponting, mainly due to audio always out of sync.

I'm using wme.

Video = wmv 9
audio wma 10 pro.

Normally I use quality vbr bit at 5000k for video, (might be getting excessive)

and quality audio vbr.

I use the vob for video input.

And use dgindex to demux audio, and delay cut to correct for any ac3 display error.

Then I use the stream editor to mux the video and audio.

But alot of my movies are showing 0ms delays from dgindex.

and when I mux the 2 togther I get delay errors.

Is there like a visual way to determine the offset?

i.e. show the orginal vob audio capture for like 30 secs.
then show the new audio caputure for 30 secs, and see the diffence?

or should i use cbr encoding, and encode the audio and video in one pass?

i'm getting to the point of just quiting this process because its getting sickening.

I must be missing something: if you don't want to keep AC3 as-is, why do you demux/remux?

He's trying to convert VOB file to WMV/ASF container with WMV9 video and WMA10 Pro 5.1 audio.

@opfreak
Only thing I can think to check av sync issues is to create an Avisynth script and preview with VirtualDub.
vid = mpeg2source("file.d2v")
aud = nicac3source("file.ac3").delayaudio(n) #where n is in seconds
audiodub(vid,aud)And yep, the 5mbps seems a might bit excessive. Heck, the original VOB's bitrate might even be close to that number.

I did this at least 100 times. With SD and HD mpegs.
No de/remuxing required.

right now i'm using my purevideo decoder.

The problems I had without demux:

2 channel audio on my xbox 360. I had to use CBR for both video and audio. I could not use VBR because the I would always get an encode error on the 2nd pass.

I love would to just load the vob, and do a single pass.

The elecard decoder I got to almost work once, gave me a goofy resolution output of like 1440x0

...I could not use VBR because the I would always get an encode error on the 2nd pass.This is because you use PureVideo video codec.
But for standard definition even this should work: just DON'T enable preview of the output window.
And use AC3Filter - never made NV audio codec work. You just need pass-through.
The elecard decoder I got to almost work once, gave me a goofy resolution output of like 1440x0I think you used Elecard 4 - I had the same AR problem with those. Use v.3
And make sure WME uses its demultiplexer.
