Converting H264 recordings to MKV format

So what do you do once you've recorded all those World Cup matches, producing 11-15Gb of files that is filling up your hard drive? Well, you need to convert them into a compressed format but at the same time as keeping the quality of the video. DivX HD is one such format, but the one I'm going to use is the MKV container format. I'm just going to see what file sizes I can achieve by leaving the video and audio in their native formats and putting them into the MKV container.

Here are the free tools that I am using to transcode to mkv:

1. Edit .ts file using H264TS_Cutter: http://www.videohelp.com/tools/H264TS_Cutter (save as .ts)
2. Process .ts file to mkv using MeGUI: http://www.videohelp.com/tools/MeGUI (following these instructions)


A sample clip (Visa World Cup advert using Pixies Isla de Encanta) is available here.

A full set of instructions by myself will appear on a nearby wiki soon! Two initial problems were solved here and here.
