playback control toolbar until the speed changes to single frame.
2. Click the Pause button to advance the video frame by frame.
• Using the front panel:
1. In playback mode move the joystick to left and right to scroll down and up
through the speed changes until single frame.
2. Press Enter with the joystick to advance the video frame by frame.
3. Press the Play button to continue playback at normal speed.
