Intro

Deinterlaced playback at double frame rate makes for a smoother movie without interlace artifacts.
Hopefully no frames are dropped on a fast computer.

Keyboard commands

Press cmd-O to open a movie. It will start playing right away.
See Playback menu for more keyboard commands.
Movie speed: cmd+ or cmd= increases speed; cmd- decreases speed
Slow motion: use speed 0.6 for PAL movies, speed 0.5 for NTSC.
Gamma: cmd-G increases gamma (making the movie darker).
Gamma: cmd-C increases contrast.
Gamma: cmd-S increases saturation.
Shift-number jumps to the numbered chapter (only 1-9)

Known limitations and problems

No reverse playback.
Even SD movies stutter occasionally.

Preferences

In the preferences you can select the screen to be used for playback (if you have more than one) and the initial speed.
You can also have all movies start in full screen mode and autoclose at the end.

Thumbnail navigation

If you hover the mouse over the bottom of the movie a thumbnail appears. Typing control-A accepts the navigation target.
If the movie was playing it continues playing from the new starting point.
For finer control let go of the mouse and use control-right arrow (move thumbnail one pixel to the right) or control-option-right arrow (move thumbnail one frame forward). Same for left arrow.
Holding down the keys accelerates the navigation.
