Usage Features:
The AG-A800's control panel provides intuitive access to all editing functions. Users can select editing modes (Assemble or Insert), choose VTRs (Player 1, Player 2, Recorder, or Auxiliary), and enter edit points using various methods: Mark IN/OUT keys with a search dial, numeric keys, or +/- keys for duration-based adjustments.
- Preview and Review: The "Preview" function allows users to rehearse edits without recording, while "Review" enables playback of edited segments for confirmation.
- Capstan Override: This feature allows synchronization by controlling the VTR's capstan speed, essential for color frame synchronized edits.
- Buzzer ON/OFF: A buzzer provides audible feedback for operations and warnings for errors.
- Edit Reference Selection: Users can choose between Time Code (TC) or Control (CTL) signals as the reference for tape position display.
- Reset Function: Resets the display indication of the selected VTR to "0" and erases its edit data.
- Servo Lock Lamp: Indicates when the cylinder and capstan servos of Player 1, Player 2, or the Recorder are locked.
- REC RUN/FREE RUN Selector: Determines whether time code increases with the VTR in REC mode or independently.
- Search Dial: Used for precise picture searching in JOG mode (still to double speed) or SHUTTLE mode (up to 10 times normal speed).
- Transition Time Display: Shows transition time in frame units for Wipe, Dissolve, or DSK modes.
- Pattern Number Display: Displays the number of patterns for Wipe or Dissolve modes.
- Special Effects: Supports various special effects when connected to the AG-SW800 switcher, including Cut, Fade In/Out, Dissolve, Wipe, and Down Stream Keyer. These effects can be applied at specific edit points (P IN, A/B, P OUT).
- Effect Memory: When connected to the AG-RM800 remote controller, the AG-A800 can memorize and reproduce special effect operations, including Video, Key, and Audio effects.
- Automatic Search (GO TO): Quickly cues up to desired points or edit points using numeric input.
