This workflow confirms the FS1-X upconverts incoming video with matting.
HD to Letterbox SD
over Video
The following workflow recalls the FS1-X to factory preset, downconverts a 1080i SDI
input to 525i SDI letterbox, keys the letterbox over a second 525i SDI video input, and
displays the result on the FS1-X Composite video output. This processing requires
2
Channel mode.
Setup • Connect a10801i59.94 HD SDI signal to the SDI1 input on the rear of the FS1-X. This
signal will be downconverted and letterboxed.
• Connect a 525i59.94 SD SDI signal to the SDI2 input on the rear of the FS1-X. This signal
will be the background.
• Ensure the FS1-X is receiving a valid reference signal compatible with the SDI2 input.
• Connect the FS1-X Composite video output to an analog video monitor.
Procedure 1. PRESET menu:
•Select 1.0 Factory Preset and recall that preset.
• Front panel interface: Push in the ADJUST knob momentarily.
• Web page interface: Select Factory Preset Recall.
This recall sets the following default values for this procedure:
• SYSTEM 1.1 Vid 1 Input is set to SDI 1
• SYSTEM 1.2 Vid 2 Input is set to SDI 2
• SYSTEM 3 Vid 1 Output Mode is set to Normal
• VIDEO OUTPUT 4 Analog is set to Vid 1.
2. If the FRC option is present, go to the SYSTEM menu:
•Select 10 FRC Enable and adjust to Disable (this sets 2 Channel mode). This menu is
not available on FS1-X units lacking the FRC option.
3. VIDEO PROC menu:
•Select 2 Video Output Format, and adjust to 525i59.94.
•Select 6 Background Fill, and adjust to Vid 2.
•Select 8 Downconvert Mode, and adjust to Letterbox.
NOTE: The H and V Output Timing settings of both Video Processor 1 and 2 must also be identical.
The factory Preset recalls 0 values.
This workflow confirms the FS1-X downconverts incoming video to letterbox, and can
key over another incoming video signal.
Conversion Across
Frame Rate Families
The following workflow converts a 1080i59.94 SDI input to 1080i50 SDI output, using the
optional FRC. This processing requires 1
Channel mode operation. In this example frame
rate conversion with and without the FRC option is demonstrated.
