960x720 Constant Rate Shooting over
59.94p
Select a format that matches the respective VARICAM frame frequency setting used when the
video was shot. Only frames set with active frame information are captured.
960x720 50p Use this when capturing content taken with AJ-HDX900, for example, whose format signals are
720/50p and 720/25p.
Points About Capture and Editing
The following explains points and precautions about capture and editing.
The capture operation procedure is the same as that for other devices connected via the IEEE1394 interface.

Shooting Video Utilizing VARICAM Features
To utilize the features of VARICAM to create good-leaking slow motion and quick motion, the speed that will be required as a result of
editing must be calculated in advance before shooting video. The playback speed is calculated by the following formula:
Playback speed (%) = frame rate of timeline÷frame rate at shootingx100
What Are Under Crank Shooting and Over Crank Shooting?
r Under crank shooting
This refers to low-speed shooting by which warp effects and flashlight effects, and stage effects such as ghost effects can be obtained.
r Over crank shooting
This refers to high-speed shooting by which stage effects using high image quality slow motion with smooth highly dense frame video can
be obtained.
Points when Using Under Crank Shooting for Quick Motion
f Shoot video with the shooting frame rate set lower than the playback frame rate.
Example:
If video is shot at 15p to create a 30p timeline, then this will result in 2x speed quick motion.
f Select a capture format ([960x720 Constant Rate Shooting 59.94p] or [960x720 Constant Rate Shooting 60p]) that matches the
VARICAM frame frequency setting used when the video was shot. If video is captured in this mode, only active frames will be captured
and these will become the file to be edited by variable frame rate.
Points when Using Over Crank Shooting for Slow Motion
f Shoot video with the shooting frame rate set higher than the playback frame rate.
Example:
If video is shot at 45p to create a 30p timeline, then this will result in 2/3x speed slow motion.
f Select a capture format ([960x720 Constant Rate Shooting 59.94p] or [960x720 Constant Rate Shooting 60p]) that matches the
VARICAM frame frequency setting used when the video was shot. If video is captured in this mode, only active frames will be captured
and these will become the file to be edited by variable frame rate.
When Shooting for Slow Motion/Quick Motion Is Not Required
Select the 60p (59.94p) capture format.
When video is captured in this mode, playback is adjusted to keep real time at shooting. Since the original speed setting is also reflected in
playback, both slow motion and quick motion are supported.However, this is not a method of effectively using the original performance of
VARICAM.
