The Genlock screens vary depending on the ROI model.
Genlock
The Genlock control offers the following options, depending on ROI model:
• Auto – use Ref Input if present, then Input signal if valid, then free-run
• Free-run – Lock to internal clock
• Ref In – Lock to the Video Reference input
• HDMI – Lock to the HDMI/DVI Input (if valid video rate)
• SDI – Lock to the SDI Input (if valid video rate)
NOTE: When HDMI or SDI is selected, ROI can lock to input formats that have a SMPTE
raster and frame rate and are within 50 ppm of the SDI output format.
NOTE: The actual resultant Genlock status is reported to the right of the selection menu.
H-Delay and V-Delay
These controls let you adjust H and V delay from the sync input by dragging the
slider or entering values in the windows on the right. Horizontal delay is entered
in pixels, while Vertical delay is entered in lines.
