PREPARATION OF EDITING TAPE The preparation of the tape for editing differs depending on whether assemble or insert editing is to be performed. The control signal (CTL) must be recorded on the tape before any attempt is made to edit. For assemble editing, the control signal is recorded at the start of the editing tape.
BASIC FLOW OF EDITING OPERATIONS Editing operations basically involve the following steps. Simple operation mode 1. Edit mode selection 2. Edit point registration 3. Execution of editing Standard mode (1st edit) Prepare the editing tape in the recorder. Select assemble or insert editing. Set the edit IN and OUT points for the player and recorder.
TYPES OF EDIT MODES AND ILLUSTRATIONS Assemble edit mode Signals are recorded continuously and successively from the start of usually a new tape (used tapes can also be used). This is the mode commonly used to make master tapes. Already recorded Recorder prior to editing P IN point Player...

TC JUMP FUNCTION Editing is not normally possible in areas where the time code is discontinuous during the preroll period. However, using the TC JUMP function, editing is performed using CTL as the reference in the preroll period and using TC as the reference after the IN point has been passed (during edit recording).
Furthermore, when the EDL (SHIFT + TC) button is pressed, the data can be displayed on the LCD screen. To scroll the page containing the displayed data up or down, press the FF or REW button of VTR2. A maximum of a hundred edits can be managed inside the laptop and accessed as desired. Their data can be changed or cleared.
EDIT DATA DUMPING TO/LOADING FROM AN EXTERNAL DEVICE The edit data entered in the EDL memory can be transmitted to an external source via the RS-232C connector. For instance, operation and control can be exercised in a wide range of systems as shown below by uploading data to a computer or down- loading data from a computer.
<Reference> External device settings and communication methods The external device settings and data communication method differ from one device to another. For details on the settings and operations, refer to the manuals accompanying the selected device, its operating system (DOS) and communications program or make inquiries with the manufacturer of the device connected.
Since no distinction is made in the EDL format between the VIDEO reference and AUDIO reference, the VIDEO reference should normally be used for the split edit data. [Example of data output] TITLE: PANASONIC EDITING CONTROLLER AG-A850(AJ-LT85) EVENT REEL MODE...
AUDIO RECORDING SWAP FUNCTION This function enables CH1 input, CH2 input or CH1/CH2 mix to be selected as the audio signals to be recorded on CH1 and CH2 of VTR2. It makes it possible to record signals from an external microphone, which has been connected to CH2, on CH1. It is also useful for internal editing from VTR1 to VTR2.

The principle behind the formation of condensation is the same as that which causes droplets of water (condensation) to form on the window panes of a heated room when it is cold outside. Condensation forms on the laptop or tape when it is moved to a location with a significantly different temperature and humidity.
