Caution on video signals
●If search images or video signals with a high level of jitter are input, images or sound may be distorted temporarily. Thus, input stable signals, e.g., those having gone through a TBC.
●A digital VCR requires that video signals for recording be delivered from a stable source. Video signals from an analog VCR must be run through a TBS or TBC.
●When a component output is executed for
Synchronization signal
In order to enhance the level of edit precision, input synchronization signals to all the devices of the editing system during editing.
For
To edit DV signals, synchronization signal in- put is required.
Types of synchronization signal:
•Synchronization signals produced by the syn- chronization signal generator inside the VCR (INT)
•Video signals from the video signal input ter- minal (VIDEO)
•Synchronization signals from the SYNC IN terminal (EXT)
Selection of synchronization signals: Synchronization signals should be selected de- pending on whether external synchronization input (SYNC IN) or video input (VIDEO IN) ex- ists or on the SYNC SELECT Menu settings. Synchronization signals are selected as shown in the following table.
SYNC IN | No | Yes | No | Yes | ||

Caution on synchronization signals
●For external synchronization signals, output- signal phase adjustments cannot be per- formed. In addition, the sub carrier cannot be locked.
●Plugging and unplugging of external synchro- nization signals or video input signals during playback causes distortion of images and sound for about 5 seconds.
