Encoding video for Nokia N8 Part 1: Getting the prerequisites

NOTE! This part downloads uses the latest version of mkvtoolnix. However, there is a caveat. Part 3 is wrong. For now, download an OLDER version of mkvtoolnix. Then this guide will work as expected.
First part in the guide on how to encode a video to work on Nokia N8 using only open source software (free).
What you will need:
- x264 (To compress the video)
- Avisynth (To convert video fps to 30)
- ffmpegsource plugin for Avisynth (Plugin to perform the magic fps changing)
- Mkvtoolnix (To mux audio and video together)
