Frame Rates Frame Rates selects the HD video frame rate associated with the video standard.
NTSC Standard NTSC Standard selects the NTSC video standard.
Composite
Downconv Composite Downconv 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).
When the Downconverter is used, an additional frame of video delay is incurred and
the analog Composite output will be one frame behind the other outputs.
