Using Variable Frame Rates (Vfr) - Panasonic AG-HVX200AP Operating Instructions Manual

Variable frame rates (VFR) (continued)

Using variable frame rates (VFR)

Standard speed shooting for movie
production
When making movies to show on a screen, a frame
rate of 24 fps (frames per second), which is the
same as for films, is the norm (1x speed). If you
use the settings below, the same kind of playback
as with screenings can be obtained. By using the
720P progressive mode and cine-like gamma,
high-quality film-like images can be achieved.

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 30
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 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.

• In the case of the 720P/24P and 720P/30P
formats, 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
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.
