Shooting in 1080i/480i progressive mode
Selecting 1080i/30P, 1080i/24P, 1080i/24PA,
480i/30P, 480i/24P or 480i/24PA in the REC
FORMAT option (page 107) of the setting menu
RECORDING SETUP screen enables shooting in
progressive mode.
30P mode:
Shoot 30 frames a second in the progressive
mode.
For output and recording, the 30-frame-per-
second signal is converted to 60-field-per-second
interlace.
This mode gives you high quality images.

24P mode:
Shoot 24 frames a second in the progressive
mode.
For output and recording, the 24-frame-per-
second signal is converted to 60-field-per-second
interlace using the widely used "2:3" ratio.
This gives you images similar to a movie shot
with film.

24P advanced mode:
Shoot 24 frames a second in the progressive
mode.

interlace using "advanced" conversion.

With the "2:3" method, frames [BoCe], [CoDe],
[FoGe], and [GoHe] shown in the illustration would
be extended over different frames which can cause
a drop in picture quality.
With the 24P advanced method, however, frames
[BoCe] and [FoGe] are cut out, leading to a
reduction in image quality loss.
If you also use a system compatible with the
advanced method, editing will also yield better
quality images than those shot in the normal 24P
mode.
• If you are not going to do your editing on such a
system, use the normal 24P method for shooting.
Note the following when shooting in
progressive mode.
• You cannot have a gain of 18dB.
• Set the shutter speed to 1/50 (OFF) or 1/60 for
best results.
• There may be a slight delay to the start of
recording when you use the 24P or 24P
advanced modes because 5 frames are recorded
at a time. When using a tape, the shortest
possible recording time is three seconds.
