ASF / WMV conversion guide
First of all a warning: ASF and WMV are crap formats for DVD rip purposes. Don't ever use them! Also, the lower the quality of your source the lower the quality of the re-encoded files so don't expect good results when you follow this guide. Most ASF/WMV files also have been encoded way below the specifications of a regular DVD rip.
You'll need the following software in this guide:
TMPG
DivX3 / DivX4 / DivX5
or XviD codec
Step 0: Preparations
Install Graphedit and Avisynth as per the readme files that can be found in both packages.
Then play your AVI in Windows Media Player 6.4 (c:\program files\windows media player\mplayer2.exe). During playback right click on the movie, and select statistics:
Then look
at the Actual rate. It will normally fluctuate a little, especially if you have
a lot of other tasks running in the background (in this case I had TMPG running
so my CPU was maxed out). In any case, if it's around 23-24fps the source has
a framerate of 23.976fps. If it's around 29-30fps it's framerate is 29.97fps
and if it's around 25fps it's actually 25.00fps.
Step 1: TMPG Setup
Start up TMPG and prepare it for .asf/.wmv input.
Step 2: Pick your target format
