10 NTSC Standard
This parameter selects the NTSC video standard. This setting only applies when
parameter 9 Frame Rate is “59.97/23.98”.
The NTSC standard applies to both the Output video standard, and the expected Input
video standard. The FS2 does not convert NTSC to PAL-M, or vice-versa.
11 Composite
Downconv
This parameter selects the type of Downconversion performed on the incoming selected
HD source input for the analog Composite (NTSC or PAL) video output.
This parameter is used only when the Video Processor feeding the Composite output
(Output parameter 5 Composite Out) is producing HD. If that Video Processor is producing
SD, the Composite Downconverter is not needed, and the format on the Composite
output is the same as seen on the other outputs (controlled by parameter 7 Downconvert
Mode for that Video Processor).
NOTE: Using the Downconverter adds a frame of video delay and causes the analog Composite
output to be one frame behind the other outputs.
12 HDMI RGB Range
This parameter selects the output range for HDMI YCbCr. Full allows a range of 0-255 and
SMPTE limits the range to 16 to 235 (see note for details).
Note: YCbCr luminance (Y) channel data ranges nominally between 16
(black) and 235 (white). Values outside of this range are typically clamped
to the valid range. This may cause confusion because JPEG JFIF YCbCr
values range between 0 and 255. Mixing these values causes video
contrast shifts. You can avoid these shifts if you maintain one range of
values throughout your system.
14.0 AES/EBU SRC
Mode
This parameter controls the mode of the audio sample rate converters for AES/EBU input
audio pairs.
NTSC (default)
NTSC Japan
PAL M Select NTSC for North America.
Select NTSC for Japan.
Select PAL-M for Brazil.
Crop (default)
Anamorphic
14x9
Auto AFD
Letterbox
Image is cropped to fit new screen size.
HD image is converted to full-screen SD with a 16x9 aspect ratio
(anamorphic).
Image is reduced slightly with aspect ratio preserved. Black is added
top and bottom, and the left and right sides are cropped.
Automatically selects the best Downconvert mode based on the
input video's Active Format Description (AFD) code. If the input
video is not carrying an AFD VANC code, the Downconverter
defaults to the mode specified in parameter menu 16.3
Downconvert AFD Default.
Image is reduced with black top and bottom added to image area,
with the aspect ratio preserved.
Full (default)
SMPTE Selects an HDMI luminance output range of 0-255.
Selects an HDMI luminance output range of 16-235.
