DivX 5.0.5 - Settings for multi-pass and VirtualDUB?

[rolandschweiger]

Hi everyone,
i have recently installed DivX 5.0.5
and i am using it to convert my movies from my
SONY Mini DV Camera to DivX.
The camera is PAL 720 * 576
and as i want good quality at low bitrates, i want to use multi pass.

Unfortunately i did not find an exact description of how ecactly to use the multi pass feature.

I tried
"original-first pass", then "origina-second pass-first" and finally
"original-secondpass-2nd".

At the first 2 stages with VirtualDUB, i left the audio processing out
and only at the final stage, i included audio conversion to MPEG3.

However, this method is very slow and i am wondering if there are better ways of doing this - for example using the preset profile for "home theatre".

Hope someone has a good solution or an exact description of how to use the 5.0.5 codec correctly ?

greetings

Possibly Solution

To use the multipass function in VirtualDub with DivX 5.0.5, try "Multipass - 1st pass" and when it`s finished run "Multipass - nth Pass"..

Hope its useful, at least it works for me

[rolandschweiger]

when i use first-pass / nth pass,
is it definately ok to leave the audio out during first pass,
and to keep the same names for the log file ?
(the codec will ask "the log file already exists, overwrite?)

[Jeff Mirage]

I allways encode the audio during the first pass so I can`t help you there..
And I never had any problems with the log file so can`t help you there eighter...

Ok this wasen`t much help but thought I had to reply..

You can leave the audio out it doesn't matter when you encode and mix that.

The log it IS ok for it to overwrite

Is there any advantage to 3-pass encoding? If so, how do I do it? I'm actually running a 3-pass batch at home now in VirtualDub, but I just kind of guessed.

I took a VFAPI AVI and set the DivX codec to Multipass, 1st pass, full processing. No audio. Save job.

Then I did Multipass, nth pass, full processing. No audio. Save job.

Then I did Multipass, nth pass, full processing. WAV audio (MP3 encoded Riff-WAV), direct stream. Save job.

Run jobs.

Is that right?

[Jeff Mirage]

It sure sounds right, I guess it`s finished now? How did it go?

I have never used 3 passes, since two passes seems to produce an ok quality... (So why waste time on a third one???)

[scottws]

I don't know. I messed something up so I scrapped it.

For some reason, I can't get the audio to sync with the video.

I followed this guide.

It worked fine for me for two other movies, but this certain one I'm doing now just will not sync up. It starts out in sync, but by the end of the 89 minute video, it's several seconds off.

I had changed keyframes from the default 300 frames/keyframe to 24 frames/keyframe, so I could split it up into 9 sections easier. Would that have something to do with it?

Oh, and it can't be my PC:

EPoX 8K5A2+ (KT333) @284Mhz

That's a damn fast computer you got there it being 2145GHZ and all but I know what you meant to say
