L, or H for Xorigin, Yorigin, LineLength, and Height. The height
can be omitted for transfers to the Diskus. If any of the numbers is
omitted it defaults to the normal values (origins to 0, length to 720,
and height to 486 or 576, depending on the TV standard).
Fields and Frames
Video can be transferred as frames or fields. A frame is twice as
long as a field and the lines are interleaved in the same way as
they appear on the display. An f immediately preceding the
frame number indicates a field transfer. The first field of a frame
is implied by default. To access to the second field the frame
number must have a + appended to it. The frame number can also
be specified in timecode, where seconds and frames are separated
by dots for the first field and colons for the second.
A transfer to 590 simply places the frame at 590, whereas a
destination filename of f590+ or f18:25 records the file as the
second field of frame 590 (18:25 in timecode on 525 line systems).
Note that in 625 the first line of a frame is part of field 1, but in
525 the first line is part of field 2.
