z When “VIDEO” is selected for the menu option REC SIGNAL,
non-standard signals output from the GENLOCK IN connector,
may degrade video quality.
z When “PROG.” is specified for the menu option V.RES (25P),
segmented-frame video is recorded, allowing you to perform
completely progressive editing. However, adding vertical
details (V.DTL) can makes the video appear unnatural. For
these reasons, it is recommended that V.DTL be set to 0.
z In progressive mode, 50 percent shutter is forcibly added to
produce more film-like motion video. To cancel this shutter, go
to the <OPTION> screen from the OPTION menu and set the
option P HALF SHUT to “OFF”.
