PULLDOWN - v0.99d, by Hard Code.
[Based on sources by Brent Beyeler (beyeler@home.com)]
PULLDOWN is a tool for modifying the encoding flags in an MPEG-2 video
stream. It is most useful for turning a 23.976fps progressive stream into
an SVCD or DVD-compliant 29.97fps NTSC interlaced stream via 2:3 pulldown.
Using pulldown with only the source file name and no additional arguments
creates a new file called PULLDOWN.M2V in your current directory.
usage: pulldown.exe [options]
options:
-nopulldown : pulldown will not insert the necessary flags for 2:3 pulldown
-framerate [23.976, 25, 29.97] (defaults to 29.97) : changes framerate
-norff : strips out all RFF flags
-tff [odd, even] : changes the field order
-notimecodes : does not recalculate timecodes for the new framerate
-prog_seq [p, i] : marks the entire MPEG stream as progressive or interlaced
-prog_frames [p, i] : marks each frame as progressive or interalced
-drop_frame [true, false] : Set drop_frame_flag for NTSC streams
-aspect_ratio [1:1, 4:3, 16:9, 2.21:1] : Change aspect ratio
