AJA Ki Pro Ultra 12G is a multi-channel Apple ProRes® recorder offering up to 4-Channels of simultaneous HD recording, or in Single-Channel mode, a 4K/UltraHD/2K/HD Apple ProRes or Avid DNxHR® recorder and player. Avid DNxHD® MXF is also supported up to HD formats in Single-Channel mode.

Ki Pro Ultra 12G offers 12G-SDI single cable simplicity for large rasters and HDMI 2.0 digital video connectivity with HDR support for both recording and playback.
A wealth of analog and digital audio connectivity answers any project’s demand for efficient, powerful and flexible workflows. For distance and remote needs, 12G and 3G Fiber SFP+ options are available.

Designed to be either portable or rackmountable with half rack wide, 2RU high dimensions, Ki Pro Ultra 12G is well suited for use in any environment.

ProRes 422 and 4444 Recording

The Ki Pro Ultra 12G can record your footage in DCI 4K/UHD 4K/2K/HD at six different quality levels of ProRes including 4444 XQ. This allows you to record your footage in the same codec accessible by many NLE systems, avoiding the need for transcoding before editing.


Avid’s DNxHD and DNxHR codecs are likewise supported, and you can record directly to them in the KiPro Ultra 12G, allowing you to take your captured footage directly into your Avid edit system. You can record a single channel of 4K using the DNxHR codec, and DNxHD is also limited to single-channel recording.


You can record and play back a single 4K stream, and you can also simultaneously record four HD streams. This allows you to capture from four different HD streams simultaneously into the same codec for editing, eliminating the need for later transcoding to make the source footage match the needs of your edit system.

Inputs and Outputs

The Ki Pro Ultra 12G Features a single 12G-SDI input and output, as well as three 3G-SDI inputs and outputs. It also features HDMI 2.0 type A input and output connectors, as well as a dedicated SDI monitor output. Integrated SFP cages allow you to source optional SFP connectors, which allow the Ki Pro Ultra 12G to work with SDI over fiber.

HDR Support

Ki Pro Ultra 12G provides this support for your DCI 4K/UHD 4K/HD HDR pipelines to HDMI and SDI compatible displays by generating HDR metadata in accordance with HDMI v2.0a/CTA-861.3 and SMPTE 352, which includes HDR 10 (PQ) and HLG for both input and output.

64-Channel Audio Support

Multichannel audio monitoring is available on the built-in display as well as the dedicated SDI monitor out and the HDMI output connector.


Ki Pro Ultra 12G supports both Square Division Quad Split format and Two Sample Interleave, offering a wide number of options to both record and play back DCI and UltraHD 4K.

AJA Pak Media

Two slots for AJA Pak media allows the Ki Pro Ultra 12G to record nearly endlessly as it will automatically roll over to a new Pak when the first one is filled. It supports Pak 2000, Pak 1000, Pak 512, and Pak 256 media, and you can format in either HFS+ or exFAT.

Closed Captioning

Closed captioning is supported following CEA-608 or CEA-708 protocols.


The Ki Pro Ultra 12G can be controlled over a LAN via the RJ45 connector, or RS-422 over the integrated DB-9 connector.


It features two sync in and two sync out BNC connectors.


The unit features redundant 4-pin XLR power inputs that support 12 to 18 VDC input from a battery or other power source. An included AC/DC power supply enables you to run the unit from mains power from virtually anywhere in the world.

Ki Protect

Ki Pro Ultra 12G includes Ki Protect, a feature that helps to ensure data integrity if a media drive is accidentally removed or loses power during recording.
