Signal Routing Examples
Since the Ki Pro Quad can receive a variety of signals via quad, dual or single link SDI,
what follows are examples of how the In Convert, Out Convert, SDI Output, Video Input,
and LUT Enable work in combination with each other.
Example 1 A Canon EOS C500 is outputting 4K or Quad HD via SDI that is RAW (at up to 29.97fps). A
1x 3G-SDI connection is made between the camera and the Ki Pro Quad. The user wishes
to encode the incoming material as Apple ProRes 444 at 4K. The incoming signal will be
debayered and an RGB Apple ProRes 444 file will be created on the Ki Pro Quad recording
media. At the same time, the RAW data without any changes in the RAW signal may be
passed along the Thunderbolt connection to a Thunderbolt-equipped host computer for
capture via the AJA CamXchange application). Additional color processing, scaling, etc.
may be performed on the computer using third-party software from Canon or others.
These example menu parameters and settings would produce the desired result:
Reviewing the Above Settings: No In Convert has been selected, so the signal is left at the 4K raster size that is presented
on the 3G-SDI connection of the camera. No Out Convert selection has been made, so
the SDI Monitor output and the HDMI Monitor output will both be 2K scaled and
debayered monitoring versions of the 4K input source. The SDI Out is set to SDI 1-4 RGB
so that the incoming signal is debayered and passed back out of the Ki Pro Quad as quad
link HD-SDI with RGB values. As noted, the Video Input is set to SDI 1 RAW; therefore, the
Ki Pro Quad performs the correct debayer processing before encoding the material to
Apple ProRes 444 as RGB. Neither an Input LUT nor an Output LUT has been applied via
the LUT Enable menu parameter, so material may appear “washed out” in recordings as
well as on monitors and may not represent the picture as it will finally be realized in post
production after color correction has been applied.
Example 2 The camera is outputting quad link 3G-SDI at up to 29.97fps, and 4x 3G-SDI connections
are made between the camera and the Ki Pro Quad. The user wishes to encode the
incoming material as Apple ProRes 422 (HQ) at a 4K raster size. The incoming signal will
be encoded to an Apple ProRes 422 (HQ) file on the Ki Pro Quad recording media. Note:
No information will be passed along the Thunderbolt connection since the source
baseband video is not from a RAW source.
