KI Pro Overview

AJA Ki Pro models are file-based recording and playback devices that create high-quality files on computer-friendly media. You can encode to Apple ProRes, Avid DNxHD, DNxHR, or H.264. With extensive video and audio connectivity from analog component to 12G, 3G-SDI, HDMI 2.0 and optional Fiber SFP modules, you can interface with virtually any type of camera, router, switcher or display. Via industry standard codecs and connections, pass on your captured files for on-set, postproduction, OTT and more. All Ki Pros are intuitive to operate, with familiar VTR-like buttons and a clear, easy-to-understand user interface, and a powerful web-browser based UI available on all models.

With six models available, AJA offers a Ki Pro that best suits your workflow requirements.


Ki Protect


The majority of Ki Pros offer Ki Protect, a feature that helps ensure data integrity if a media drive is accidentally removed or loses power during recording. The Ki Protect feature automatically pre-allocates recording space on the media drive for video, audio and timecode when the record button is pressed.

While recording, the file header is then continuously updated every time new data is written. That way, the only loss that should be incurred is the last few frames that were in transit to the media drive when the operation was interrupted. Frames that are already recorded will be preserved, providing greater peace-of-mind on-set and in the studio.

Remote Configuration and Operation

Ki Pro products can be remotely controlled from anywhere using a web browser on any OS with their built in webserver. Multiple Ki Pro Ultra Plus, Ki Pro Ultra or Ki Pro GO units can even be controlled from a single web browser interface making them an ideal solution for multi-camera recordings. Most Ki Pros also offer a standard RS-422 port for direct connectivity to RS-422 controllers.


Reliable Storage Media

Capture directly to rugged and reliable AJA PAK SSD media with Ki Pro Ultra Plus and Ki Pro Ultra. Ki Stor SSD is the media for HDD for the Ki Pro Rack PAK and Ki Stor Media; as well as their corresponding Docks for computer transfer are available from AJA resellers in a variety of capacities to best suit the demands of your production. Widely available standard USB media is used for Ki Pro GO.

AJA DataCalc

AJA DataCalc is a mobile OS application for iOS, iPadOS and Android, offering two modes for storage and time calculations based upon raster, frame rate and codec choices.

DataCalc - Calculate your storage needs before capture.

TimeCalc – Calculate the run time of materials you can capture by storage size.

Layouts - Powerful Multi-Input Video Processing

5608-HELO Plus Screen Shot PiP lower thirds.png

HELO Plus brings the exciting layouts feature, allowing multiple inputs to be combined into a single screen with a graphic element overlay. A layout enables the user to combine the SDI input and the HDMI input into a single output stream and then add a graphic (video + key) into that composite. The layout can have up to 3 layers, and their priority can be arbitrarily adjusted to suit the customer’s needs.

In addition to the layering engine, both the SDI and the HDMI layers can be arbitrarily downscaled and positioned anywhere in the frame. Effectively, each live video source can be used in its picture-in-picture (PiP) element.

The system also has an internal matte generator, which can be used as the background. In this way, the graphic can be keyed over the dual PiP images, which are “over” a flat matte background.

The system can accurately switch from one layout to another frame, allowing the user to “cut” between layouts during a streaming session. Layouts are stored in one of the 20 Presets, allowing users to recall all of the parameters needed for a specific purpose. There are 10 layouts stored in each preset, so the user recalls the show’s preset and can then switch between those 10 layouts at will.

The graphics system is equally impressive - The system stores 90+ images in its internal, non-volatile memory.

Extend your recording capabilities through the use of external (NAS) storage. Simply connect your storage to the Ki Pro GO over a standard Gigabit Ethernet network and take advantage of all the features of networked storage. Use your NAS as your primary storage location or as secondary (backup) media – you can even record to NAS and local, USB-based storage simultaneously, giving you the perfect combination of shared storage and portability.

Ki Pro GOs elegant and intuitive UI makes NAS set up easy. Simply enter the IP address of the storage, any required user credentials, and the SMB dialect you wish to use, and you’re ready to record. Ki Pro GO simplifies set up even further by auto-detecting the SMB dialect of your NAS system and self-configuring to match. SMB credentials can also be stored in system presets and recalled at the push of a button for “on-the-fly” system reconfiguration.

Local and NAS Recording 

In this workflow we can see the Ki Pro GO is receiving video from camera sources 1 through 4. The Ki Pro GO is recording locally to USB drives connected to the front USB3 inputs. The Ki Pro GO  is also connected via Gigabit ethernet to a Gigabit ethernet switch and a NAS for simultaneous recording. Editorial, Graphics and Digital Asset Management (DAM) workstations are also connected to the same network as the Ki Pro GO, with both having access to the NAS. 

KI Pro Rack
