Undercrank shooting
This way of shooting provides quick motion effects
used to present such scenes as the movement of
clouds, someone standing among crowd of people,
and moves made by martial artists. If, for instance, you
have shot scenes using the 24P recording format for
specifying the playback frames, you can double the
speed of the quick motion effects by setting the VFR
recording frame rate to 12 fps.

Overcrank shooting
This way of shooting provides slow motion effects
used to show car chases as well as action scenes,
climax scenes and other dramatic presentations.
If, for instance, you have shot scenes using the 30P
recording format for specifying the playback frames,
you can obtain slow motion effects with the speed
halved by setting the recording frame rate to 60 fps.
Images in the 720P progressive format will create
smoothly flowing slow motion sequences with a high
picture quality.

(2:3) conversion system for editing extends the
BoCe, CoDe, FoGe and GoHe fields into adjacent
frames, which causes a drop in picture quality.
