Encoding video with the XVID codec

I assume you already downloaded and installed Virtual Dub. If not, click the link above to get the latest version. Furthermore you need to have the XViD codec installed. To get the latest version of the XViD codec you can for example visit kepi.org - a XViD developers website that offers the latest binaries/executables of the codec. Download and install it.

To setup the video encoding selection open the Video menu from the top menu bar. Make sure it's set to either "Normal re-compress" or "Full processing mode". Otherwise you can't select the "Compression" entry and the video steam will be kept then.

1. Select the XViD MPEG-4 Codec from the codec listing
2. Click Configure

3. Select Two pass, First Pass to prepare the final encoding. The profile AS@L5 is default and should be kept.
4. Press OK and the first video encoding pass starts.

5. Set Encoding Type to Two pass - Second pass.

Then set the target bit rate to the value where you find the video quality acceptable. The start values I usually use for the first second pass encode:

1. 1024kbps on a 800x600 movie running at 25 frames per second (fps)
2. 1492kbps on a 1024x768 movie running at 25 frames per second (fps)

6. Hit OK to start the second encoding pass.

After the second encoding pass finished you should be able to watch you self encoded video now using your normal video player. If you like the quality, you're finished now. If you think the quality is still to low, you can repeat the second step with different quality settings until you like the results. The first pass does not need to be repeated after it was done once.
