JVC GY-DV550 10. S.S.F. Super Scene Finder FUNCTION, Explanation of the S.S.F. Function, Setting

9. TIME CODE OPERATION 9-4Recording Time Codes in Continuation of Time Codes Recorded on Tape

The GY-DV550 also incorporates a time code reader. Therefore, when the unit enters record mode from record-pause mode, it can read the time code data recorded on the tape and record time codes in continuation of the existing data. The recorded user's bit data is identical to the user's bit data recorded on tape.

*However, approximately ±1-frame variations may occur in scene transition accuracy. To enable this, set the time code related switches as follows before starting recording.

10. S.S.F. (Super Scene Finder) FUNCTION

10-1 Explanation of the S.S.F. Function

During recording, the S.S.F. function records the time code data at the point of time of a desired recorded scene in the unit's memory. Using the S.S.F. data stored in memory during after-processing of the recorded image allows efficient use of the tape. The S.S.F. function comprises the two modes CUE and MARK. Select the mode using the VCR Setup Menu item No. 398 S.S.F. MODE. When the VCR Setup Menu item No. 398 SSF MODE is set to CUE MODE or MARK MODE, the time code generator’s running method is internally set to the REGEN mode. When shooting in either of the modes, the time code data is stored in the unit's memory when the TAKE button on the front section is pressed. The model ID data, reel number, the number of each scene, and the time code data of IN points, OUT points, and CUE points are

• Set the VCR Setup Menu item No. 302 BACK SPACE to “STANDARD”.

•Set the VCR Setup Menu item No. 516 DISPLAY SELECT to “TC”.

☞ See page 75.

Set the counter display to show time codes or user's bit data.

Set the TC GENE switch to REGEN.

•The framing mode of the time code will be the mode auto- matically recorded on the tape (drop frame or non-drop frame).

recorded as S.S.F. data.

CUE Mode:

When the TAKE button is pressed at the desired scene during shooting of a given cut, the time code data at that point is stored as CUE data in the unit's memory. The time code data at the time when recording is started or stopped with the VTR TRIGGER button are stored in the unit’s memory as scene data.

	Note:
•	Leave an interval of at least 5 seconds between memorization of CUE data.
	If the TAKE button is pressed within 5 seconds from the previous point, the new point is not memorized.

9-5 Reproducing Time Codes
The GY-DV550 incorporates a time code reader. During playback, the time code or user's bit data recorded on the tape is displayed
on the counter display.
	 Set the VCR Setup Menu item No. 516 DISPLAY SELECT to
	“TC”.
	☞ See page 75.
	 Set the counter display to indicate time code or user's bit
	data.
	 Reproducing time codes
	Press the PLAY button.
NG OPERATE	• The “PB” indicator lights up on the display and the time
	code or user’s bit data are indicated.

• In the CUE mode, time code log data stored on the camera memory may differ from the actual time code recorded on tape
at the time of pressing the TAKE button. This difference may be within 3 frames and it is not a malfunction.
 MARK MODE
During shooting of a given cut, press the TAKE button at beginning of a desired scene and then press the TAKE button again at
the ending of the scene.
The time code data at the point where the TAKE button is pressed first becomes the start point of the scene and time code data
at the point where the TAKE button is pressed the second time becomes the ending point, and both are stored in the unit's
memory.			Cut

•When playing back sections where the time code is not recorded, the time code progression stops.

The playback mode continues.

Note:

•Time code more than two hours can not be displayed correctly by consumer DV equipment, which has no capability to display more than two hours.

•The time code being played back will not be outputted to the TC OUT connector.

•The number of scenes that can be registered is 127, and up to 238 registered scene numbers can be stored in memory. When either of these capacities is reached, the indication showing the number of registered scenes on the viewfinder screen becomes “M: - - -”.

•Up to 253 CUE points can be stored in memory.

For each registered CUE point, the scene number decreases by two.

•When recording in the S.S.F. mode, the reel number (cassette number) for each cassette is recorded in the memory of the GY-DV550 and on tape.

•When the videocassette is replaced, new S.S.F. data is generated. S.S.F. data for six videocassettes can be stored in the internal memory.

Before recording the seventh cassette in the S.S.F. mode, be sure that necessary data has been transferred from the memory to the non-linear editing controller or other component, or write data to the tape for each recording. ☞ See page 69.

Note:

•When recording is not performed in the S.S.F. mode, be sure to set the VCR SETUP MENU item No. 398 SSF MODE to OFF.

•Be sure to record S.S.F. data continuously on the same tape. It is not possible to rewind the tape for overwriting during the recording.

If the tape is rewound in the middle of a recording, or after similar operation is performed, be sure to use the Scene End Cue

Up function in order to ensure that new data are recorded in continuation of the existing data.

☞ See “About the Scene End Cue Up Function” on page 69.

*In the S.S.F. mode, the STBY/SAVE switch does not activate the VTR save mode. (The save mode is activated by a long pause.)
