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.
