Our Customers & Partners


The Ki Pro Ultra 12G DCI/UHD/HD Recorder and Player is a portable media recorder with a built-in 4.8" LCD screen that is well suited to location as well as studio recording and playback. It supports recording a single 4K stream, either DCI or UHD 4K, as well as multiple HD streams in ProRes. Avid DNxHR and DNxHD recording are supported for a single channel in either 4K or HD. The Ultra 12G features a 12G-SDI input and output, as well as three 3G-SDI inputs and outputs. It also features a dedicated SDI monitor out, with overlays available in the menu system, and a rotary menu select knob with push-button VTR controls.

An integrated Ethernet connector allows you to control the Ki Pro Ultra 12G via a computer and web browser, and there's a DB-9 connector for RS-422 control. The unit will easily integrate into a control room or OB van. Two media slots for AJA Pak media allow you to record endlessly as the Ki Pro will switch over to the empty recording media when the fist AJA Pak is full. The half-rack width and two rack height make this a highly portable unit and also suitable for rack-mounting with optional accessories. The redundant XLR power inputs allow for catastrophic failure of one power source with a second one as a backup, so you don't lose a frame when recording.

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.
