View Full Version : Xmpeg - Big divx

I convert a dvd (reservoir dogs) to divx using Xmpeg, following this guides: "Xmpeg Conversion Instructions" and "Setting up Xmpeg"
I used Divx 4.02 Two Pass Encoding. I resize it to 512 width, removed all the black space, I decoded the sound to mp3 128 48.

But the output file was like 1200Mb!

Could some1 tell me which setting should I change? on the codec? the sound? the iDCT? etc...

10x all

I assume you mean divx5.02, there was a divx4.02 once, but it's almost a year old.
You need to set the bitrate, in the divx codec config, to reach your desired filesize, I'am sure the was covered in the guide.

no, it's 4.02 :) and there is nothing about the bitrate

would you give me some tips about bitrate, sound, quality...
what's better, mp3, divx audio? which quality?

10x alot

Then you should definetly upgrade to 5.02.

To get a predictable filesize, you have to calculate the appropriate bitrate and enter that into the divx codec configuration as explained here

and you should be able to find a bitrate calculator here

The divx audio codec is a hacked version of microsofts wma audio codec, unfortunatly I don't have much experience with this codec.

It is likely that the sound stream is not in MP3, but the space-consuming, uncompressed, PCM WAV. Flask has that occasional problem, and XMPEG, being a Flask derivative, is prone to this as well.

What I suggest you do is process the audio separately. Here's a quick run through:
1. Use Graphedit or Vob2audio to extract the audio as .wav
2. If you wish to amplify the volume, use a sound editor, such as Cooledit
3. Convert the .wav file to .mp3 using any MP3 encoder, such as LAME
4. Mux the video (that you are creating using XMPEG) with the .mp3 file using nandub

No changes on XMPEG need to be done, except, of course, to disable the audio processing. :)
