The video is encoded with Windows Media Video 9 Professional (VC-1/MPEG4 Part 10) and Windows Media Audio 9.2. The size and quality of these codecs are superior to MPEG2. The only downside is that it is a little more CPU intensive than MPEG2. The other options for MPEG4 is h.264 (more CPU intensive) and Xvid/DivX (MPEG4 Part 2, requires users to download/install a codec or use a third-party player).
To reduce the size, I would suggest lowering the framerate to FILM speed or 23.976 fps. Since abec is probably running at a 16:10 resolution (like 1920x1200 or 1680x1050) the best resolution for 720p HD is 1152x720 (which what the video is). I did notice the max bitrate was not limitted in the video and at some point reached 20Mb/s. For 720p content, you can probably get away with a max bitrate of 4MB/s.
The sharpness/clarity of the resize depends on the resample method being used. For shrinking video content, a high quality bi-linear OR a custom bicubic algorithm designed for shrinking images should be used. I personally use Spline or Lanczos.
