4.12. Event Marker Function
The APX-i2’s Event Marker function makes it possible to record a frame number, on the
fly, at each external marking signal so that you can jump to the marked frame (event
frame) when playing recorded images. In addition to triggering points, these event
marks given at any moments of interesting event will let you play back such interesting
events quickly. Up to ten event frames can be marked in each partitioned section.
Marking is done at an edge of the incoming marker pulse. The immediately subsequent
frame after receipt of a marker pulse is recorded as an event frame. The following
describes how to place event marks:
1. Press the MENU button on the keypad to display the menu list. Move the joystick to
select the GENERAL IN menu. Using the joystick in the GENERAL IN menu, select
[EVENT POS] or [EVENT NEG]. EVENT POS marks an event at the rising edge of
the marking signal and EVENT NEG at the falling edge.
2. Send pulses into the GENERAL IN connector each moment you see an interesting
event during a recording session.
3. Up to ten marking pulses are accepted in a session.
4. Recording comes to an end.
5. Press the LIVE/MEMORY button to switch to the MEMORY mode.
6. Press the
△ or ▽ FRAME RATE button to jump to the first marked event. At each
press on either button, playback jumps to previous or subsequent event frames.
7. While an event frame is displayed on the screen, the text shows [EVENT FRAME x]
where the x is a number between 1 and 10 each representing the serial number of an
event frame.
Note: This function is not available in the DUAL FRAME RATE operation mode.
