What is the source of the test clip?
Guess what... PAL laserdiscs!!!
Second test clip - 1000 frames, 1280x720 25p, no audio, compressed at 8000kbps with x264 - youtube link
Could be downloaded here: http://www.sendspace.com/file/e6m9nh (37MB)
At 8000kbps, it's definitely better and close to the original uncompressed.
Next time, I'll post clip from NTSC DTS laserdisc.
