Helpful HDMI configuration
guidelines:
Ki Pro Quad v5.2r3
NOTE:
While the Ki Pro Quad can accept input signals of up to 4K (4096x2160) 59.94fps, 4K and Quad
HD recordings are limited to frame rates of 29.97fps or lower. The Ki Pro Quad can be used as a
pass-through or "debayer converter" device for 4K or Quad HD 50fps and 59.94fps signals.
NOTE:
The Ki Pro Quad can perform RGB to YCbCr color space conversions, but it cannot perform
YCbCr to RGB color space conversions. This means that if the input signal is YCbCr, you cannot
select an RGB output and produce a proper output.
NOTE:
SDI 1 RGB and SDI 1 YCbCr high frame rates (in excess of 29.97fps) are supported by 3G-SDI.
Be sure to connect the AJA Ki Pro Quad to a 3G-SDI capable device in these cases. If a 3G-SDI
capable device is not available, RGB and high frame rate YCbCr may be output via SDI 1 and
SDI 2 as "dual link" 1.485Gbps."
This parameter allows the 3G SDI output to be configured for either Level A or Level B.
While many 3G SDI devices will support both Level A and Level B, some devices may
need a specific 3G SDI selection to operate as expected.
Level B (default)
Level A
This parameter determines whether scaled or full raster video will be output.
NOTE:
The Full Raster selection only has an impact on the output when a 4K or Quad HD video
source is used.
Scaled (Default)
Full Raster
Limitations to be aware of when Full Raster is selected and a 4K or Quad HD video source
is used:
• HDMI full raster output is disabled when the video source is a 4K RAW signal that must
be debayered. For example, when the Ki Pro Quad is used with the Canon C500, 4K or
Quad HD HDMI output during E-to-E or recording is not supported. If realtime debayer,
recording and 4K or Quad HD HDMI monitoring is needed, consider the use of the AJA
Ki Pro Quad 4x SDI outputs connected to an AJA Hi5-4K Mini-Converter. Note: 4K or
Quad HD HDMI output is possible during playback when Full Raster is selected because
debayer processing is no longer required.
• If Full Raster is selected and the video source is 4096x2160 at any frame rates other
than 23.98 or 24 fps, then the output is disabled. HDMI 1.4 only provides support for 4K
4096x2160 at 24Hz. However, the Ki Pro Quad may be configured for an In Convert>4K
Crop to Quad HD or an Out Convert>4K Crop to Quad HD so that 4096x2160 signals
greater than 24Hz may be output as Quad HD 3840x2160.
• The maximum supported frame rate for 3840x2160 is 30Hz as specified by HDMI 1.4.
• Full Raster output disables the Super Out feature; superimposed timecode and
transport state is not possible with a 4K or Quad HD HDMI output.
• Determine your video source format and frame rate.
• Decide whether you want a Full Raster or Scaled output.
• Determine whether your connected device can support 4096x2160 or 3840x2160;
remember that 4096x2160 is only supported for 24Hz.
• Remember that the Progressive Playback menu parameter needs to be configured for
Progressive for HDMI output.
For use with devices that accept or require Level B.
For use with devices that accept or require Level A.
The HDMI output is limited to 2K or HD.
The HDMI output may produce 4K or Quad HD.
