Using Divx, audio too big

[abcdefg1675]

The name says it. I encode most of my stuff using either raw avi or divx 4/5/6. I noticed when I run it in nandub, the audio takes up nearly 2x the space of the video. This isnt right.

I looked on this site, how to get a .wav out of the .avi file. I ran that through Yamp, and made a 160Kbps mp3.

Exactly how to I remove the .wav out of the avi, and then encode with Divx so my video file wont be so huge?

a three-minute video should not be 78MB...

Btw... Yeah, I am a noob :o .

try Autogk if your final format is Divx. it will convert the audio to mp3 ad the video.

you can use virtualdubmod to extract to wav, encode the wav with belight , then encode the video with virtuldubmod, multiplex the video and mp3 back together with virtualdubmod or avimux.

for avi sources follow the post below

1) Load the original .AVI file into VirtualDub (or NanDub)

2) Set "Video" to "Direct Stream Copy"

3) Set "Audio" to "Full Processing Mode"

4) From the "Audio" dropdown menu, select "Conversion" - and select the "MPEG Layer 3" (.MP3) setting of your choice

5) Save the .AVI with a new filename

With Vdubmod, there are 2 problems.

No audio drop-down menu.

and, the video and audio slowly get out of sync. I get a couple hundred asyncronis or desyncronis audio time stamp errors.

I will try the other method of converting the AC3 file first.

I tried opening the wave with YAMP or with sony sound forge, and it tells me its not a PCM wave, but microsoft media player runs it fine... Oh well.

I will use the audio conversion program mentioned earlier and try that out with divx.

With Vdubmod, there are 2 problems.

I mentioned only VirtualDub (meaning the standard VirtualDub) and NanDub, not VirtualDubMOD. In VirtualDubMOD, click on the "Streams" dropdown menu to locate the audiostream.

the video and audio slowly get out of sync.

A) If the difference between audio and video is constant throughout the video:

Load the file into VirtualDub, VirtualDubMod, or NanDub.
Set BOTH "Video"(VirtualDub, VirtualDubMod and NanDub) and "Audio" (VirtualDub and NanDub - VirtualDubMOD>"Streams>"Stream list") to "Direct Stream Copy".
From the "Audio" dropdown menu, select "Interleaving" (For VirtualDubMOD, rightclick on the listed audiostream and then select "Interleaving")
Under "Audio skew correction", set an appropriate number of milleseconds (positive or negative) in the box labelled "Delay audio track by"
Save with a new filename

B) If the difference increases as the movie plays:

From under the "Video" dropdown menu, select "Framerate" - and select "Change so video and audio durations match"
Save with a new filename

Let us know of your success ;>}

I will try all this soon tonight.

I have had a seperate thread (http://forum.doom9.org/showthread.php?t=97719) about this audio/video issue. it gradually gets worse and worse as the video goes on. it starts out fine, then 2 minutes into the movie... Bleh, its awfull. Nearly 10 seconds off.

Btw, selecting it to align the audio and video doesnt help much. It makes the shift not as bad as before, but it still gets horribly wrong within a few minutes.

Ive tried robot4rip, virtual dub, virtualdubmod, dvd2avi (which does not work at all on my pc) ive tried dvdshrink, which complains about an encryption error.

Im nearly ready to "throw in the towel". Not quite yet, but getting there. ;)

Like I said in the other thread, if anyone has some spare time, I do have VNC server on this pc. VNC is a client/server software set (freeware) which lets you connect to my computer, move the mouse around, type stuff in, and see what i see. It will be laggy due to my 64k internet connection, but if anyone thinks they know some magical secret to this that I dont understand... or just curious as to how I keep screwing this up... PM me
