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 <TC/UB> screen from the MAIN OPERATION page and set it in the TC VIDEO SYNCHRO item.

Set by referring to the connection example.

Note

In the 1080-23.98PsF or 1080-24PsF mode, set the 23.98PsF or 24PsF HD signal as the reference signal and input a 24 frame time code to the TC IN input.

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.
