This button controls
toggles an overlay for files are displayed at an increased framerate
("pulldown") on an interlaced display, accomplished by repeating
parts of a frame a second time (PAL) or occasionally a third time
("3:2 pulldown", for NTSC). The display is active when the file is
encoded at the lower framerate (usually 24 FPS) but must be
displayed for TV purposes at 50 or ~60 frames per second. The
excerpt from the main dialog overlaying the top VGS screenshot shows
that this file was encoded at 23.976 FPS but is intended to play
back, on a TV anyway, at 29.970 FPS. This is less relevant on a
computer, where it the player will probably just play it back at the
lower frame rate, "non-interlaced" (progressive scan). This feature is only available for certain MPEG-2 files and may still have a few bugs as of GSpot v2.60 vb00 |
