Video
The distortion is less visible in the embedded videos than in the real subjective tests due to lossy compression. For a better visibility, you could either view the embedded videos by choosing the highest video quality (start video, click the gear on the left of the YouTube logo and choose HD, then restart) and under full-screen mode, or you could download the high-quality videos (links available on the page)
