Sony F23 Specifications page 9

Over- and Undercranking
The F23 camera and SRW-1 recorder put you
in command of time itself with overcranking,
undercranking and variable speed ramp effects.
The SRW-1 can play these effects in the field, so
you can confirm that you've got exactly the shot
you want before you strike the set.
There are no "pad frames," no sacrifice in
picture quality, no external processing and
no external hardware required.
Overcranking and undercranking require the
optional HKSR-102 picture cache board. This
enables variable frame rates from 1 fps to 60 fps
in 4:2:2 mode, or 1 fps to 30 fps in 4:4:4 mode.
Sony will support frame rates of 1 fps to 60 fps in
4:4:4 mode planned for the winter of 2007 with
the additional
HKSR-103 RGB 60P
processor board.
Time Lapse with Speed Ramps
To make the clouds race by or the sun set in an instant, the F23 and SRW-1 also provide Interval Recording,
the electronic name for time lapse photography. You get gorgeous effects from 60 fps to 1 fps. Three
automatic speed ramp modes plus manual speed ramp enable you to vary the effect at will. Time lapse
requires the HKSR-102 picture cache board.
Long Loads
A single BCT-40SR tape can hold up to 50 minutes
of content (at 24P in Normal Quality 4:2:2 mode) or
up to 25 minutes in high quality 4:4:4 mode. Using
two SRW-1 recorders in tandem and the SRPC-1
processor, you can also record without time limits.

In-Camera Sound Recording
When docked to the F23, the SRW-1 also captures
two channels of digital audio with superb 24-bit
quantization and 48 kHz sampling.
