As a result of processing to convert the video captured by the imaging devices from a progressive signal to an interlace signal, video signal delays will occur in the camera. Since time is required for making the 2:3 pull-down from the 24P frame, there is a video signal delay in the camera. When recording from a device that can record images without a delay and the unit is connected in parallel, it is necessary to synchronize the time code. To set this timing, open the screen from the MAIN OPERATION page and set it in the TC VIDEO SYNCHRO item. Set by referring to the connection example. Setting of the TC VIDEO SYNCHRO item Item Variable range Remarks TC VIDEO 0 SYNCHRO 1 2 3 For setting to correct the time code according to the delay of video signals. 0: Do not correct. 1: To delay the time code to be input according to the timing of the video images. 2: To forward the time code to be output according to the timing of the video images. 3: To delay the time code to be input and forward the time code to be output, respectively, according to the timing of the video images. Example 3: When the unit and an external device are locked to the external time code generator, which is connected externally, and when simultaneous recording is made by using the TC OUT output signals.

If the VTR is capable of recording the HD SDI time code, it is possible to receive the time code output from the HD SDI A · B output, and synchronously record video with the time code. In this case, it is not necessary to supply a time code output signal to the VTR. Example 4: When the unit and an external device are locked to the external time code generator and when several units of the camera are connected in a cascade configuration.
