•
To lock other devices externally to the AG-
HPX250P/EN, as the master device, make
sure that the other devices are in the same
camera mode as the AG-HPX250P/EN. Note
that if some of the connected devices use
interlaced scanning while other devices use
progressive scanning, there may be breaks
in the video and time code.
•
When 24P, 24PA or 24PN (native) is selected
and the time code is externally locked, be
sure to select a non-drop frame time code.
The time code cannot be externally locked
when drop frame mode is selected. When
the time code is externally locked, the
video may be distorted, but this is because
of adjustment to 5-frame segments and not
a malfunction.
