5.5. Block Playback (Playback of
Clips of Interesting Scenes)
Playing a high-speed recording footage is time-consuming. For example, a footage
recorded at 2,000 FPS for one second takes 66 seconds to play back at 30 FPS: it
takes over one minute to see a strip of recorded 2,000 frames from end to end. In many
cases, however, the frames of real interest to you are only a few or several tens of the
entire footage.
The APX-i2’s Block Play function lets you see only a portion of special interest to you
out of the entire recorded frames. All you have to do is pick first and last frames of a clip
you want to play.
The following describes how to use this function.
1. Press the LIVE/MEMORY button on the keypad to turn the system into the
MEMORY (Playback) mode.
2. Press the PLAY button to play the footage in the usual manner.
3. Press the START button on the keypad at a frame that you wish to make the first
frame of a clip.
4. Press the END button on the keypad at a frame that you wish to make the last
frame of a clip. Now the clip of your interested frames has been defined.
5. Press the BLOCK ON/OFF button on the keypad and make sure the LED has
lighted up. Now the system is in the Block Play mode.
6. Now the system plays back the defined clip only. Start playing the clip in the Block
Play mode as many times as necessary. You can use all playback buttons - FR,
REV, PLAY, FF, PAUSE and STOP.
7. When you are done, press the BLOCK ON/OFF button to exit the Block Play mode.
The clip setting is cancelled.
