signals converted into 60 fps interlaced. Video output

COMPONENT OUT terminal will be down-converted to
60i using the 2:3 pulldown method.
SD
24F (2:3) Mode
Signals are down-converted to 60i using the 2:3
pulldown method. This 24F mode is suited for
playback on a TV screen but may require the
extension/compression of some frames while editing.
24F (2:3:3:2) Mode
Signals are down-converted to 60i using the 2:3:3:2
pulldown method. This 24F mode is ideal for extracting
true 24 frames per second in order to transfer to film
simply by discarding the 3:3 adjacent frames (bc and
fg in the figure).
