Using variable frame rates (VFR)
Standard speed shooting for making
commercials and dramas
When producing commercials and dramas to be
shown on a TV screen, as in the case of HDTV/
SDTV and other broadcasts, a frame rate of 25 fps
(frames per second) is the norm (1x speed).
If you use the settings below, the same kind of
playback as when the programs are broadcast can
be obtained. Commercials and music clips will be
recorded with a high film-like picture quality while
the number of frames is also ideally suited to TV
broadcasts.

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 25P 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.

720P/25P, 720P/25PN Set to 24 fps or lower.*
In the case of the 720P/25P format, the quick
motion effect can be obtained by using a
nonlinear editing system to process what has
been recorded. •
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
25P recording format for specifying the playback
frames, you can obtain slow motion effects with the
speed halved by setting the recording frame rate to
50 fps. Images in the 720P progressive format will
create smoothly flowing slow motion sequences
with a high picture quality.

720P/25P, 720P/25PN Set to 26 fps or higher.*
In the case of the 720P/25P format, the slow
motion effect can be obtained by using a
nonlinear editing system to process what has
been recorded.
* You can select any of 20 recording frame rates
ranging from 12 frames per second (fps) to
50 fps. (Page 97)
