Panasonic AG-HPX300 Operating Instructions Manual page 62

In the unit, there is a video signal delay in the camera,
which is required or the process of converting video
images taken with the image-shooting element from the
progressive signals to the interlace signals. 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 VTR MENU page and set it in
the TC VIDEO SYNCRO item.
Set by referring to the connection example.
