VSync

[J7N]

The Wait for vertical blank option in BSPlayer sometimes does nothing. Or shall I say, DirectShow doesn't always allow to turn vsync on.

A new version of Media Player Classic (a real video player) has recently been released. One of its goals is to adress tearing.

If VMR9 is active you can press Ctrl-T to test for or demonstrate tearing and video jitter. Other output modes could use similar pre-rendered test clip. The two red lines should appear perfectly straight. Jitter will cause them to jump an uneven distance every rendered frame. In a perfect jitterless video the bars will move across the screen smoothly.

If you fail to acknowledge that jitter and tearing is a problem, then I wonder what are you looking for in your beloved HD. At higher resolutions the timing error will span more pixels and become easier to notice.
