Ki Pro®

Portable file-based HD/SD recorder and player.

Ki Pro combines the power of a file-based recorder with the familiar controls of a tape deck in a portable format that you can carry with you, anywhere.

The original ProRes recorder

Ki Pro established a new paradigm for tapeless video recorders by being the first recorder to offer support for creating Apple ProRes 422 files, which revolutionized how footage could be moved efficiently from production to editorial. Editors are able to work with footage immediately without the need for special file importers or transcoding steps. The workflow is simple: record with the Ki Pro, remove the the KiStor Storage Module from the Ki Pro and connect the KiStor Storage Module to the edit system via built-in connectivity.

Unify formats - speed workflows

AJA's high-quality up/down/cross-conversion makes it easy to unify SD, 720p, and 1080i and create a single desired format for your project. The multitude of video and audio connections such as SDI, HDMI and analog make integrating Ki Pro with other production equipment easy.

RS-422 Control

RS-422 control allows Ki Pro to integrate easily with supported editing systems and external controllers allowing it to fulfill several of the functions of a traditional VTR. Supported NLEs can even perform assemble edits directly to the Ki Pro.

Ki Pro's RS-422 control can also be used to link a traditional VTR with Ki Pro for direct editing control. Use the editing controls on properly equipped VTRs to control Ki Pro for machine-to-machine transfer of video and audio. This allows tape footage to be captured directly as files on Ki Pro without the need for a separate edit controller.

10-bit, full raster recording

Big on quality - but not on file size. Recording 10-bit, full raster files, Ki Pro gives you high quality images that easily stand up to post processing requirements - and client scrutiny.

Compared to 8-bit recording devices, 10-bit 4:2:2 recording (when supported by the codec) provides better quantization, giving a superior representation of the original scene and allowing for more flexibility in post production when adjusting color and balance.

By utilizing efficient ProRes codecs, file sizes are kept in check so you won't need to blow your production budget on extra storage.



Ki Pro's extensive connectivity ensures that you will be able to interface with virtually any gear in your production workflow. The rear panel is packed with connectors which include: SDI input/output, HDMI input/output, component analog input/output, balanced and unbalanced analog audio input/output, LTC input/output as well as LANC.Content

Reliable storage media

Ki Pro captures directly to reliable AJA KiStor media. KiStor media are available as HDDs or SSDs in a variety of capacities to best suit the demands of your production environment. KiStor modules also feature built-in FireWire 800 or USB 3.0 connectivity for direct connection to your editing system using standard interfaces. KiStor media may also be used with the optional KiStor Dock which features a Thunderbolt™ connection for lightning-fast data transfers. 

Note: A KiStor 500GB module is included with every Ki Pro purchase.

Remote configuration and operation

On set or in a machine room, Ki Pro is equipped for advanced remote control and configuration. With a standard Ethernet LAN connection to a host computer and any web browser, all Ki Pro parameter settings, clip selection and transport controls can be controlled; no additional or special software installation is required on the host computer. Multiple Ki Pro units can even be controlled from a single web interface making Ki Pro an ideal solution for multi-camera recordings. Complete developer tools are also available allowing advanced users to script and automate Ki Pro for custom applications.

Familiar controls and operation

Just like a traditional tape deck, Ki Pro features straightforward and dedicated transport buttons - record, play, stop, rewind, fast forward - making the device easy to operate with minimal training time. The current status of the system and key configuration information is clearly displayed on the built-in screen. Additional operational information can be found in the STATUS menu which can be accessed even when recording or playing back.

The Ki Pro operating system offers users a flat menu structure that is easy to navigate with menu parameters presented in clear and understandable language.

Automatic Camera Control

Using the Camera Data menu parameter, record start/stop operation can be trigged automatically with select cameras. Even file names can be reproduced on the Ki Pro to match the camera native recordings. Automated start/stop can also be accomplished via LANC when connected to properly equipped cameras.

Ethernet file transfer

Because of its network connectivity, media can be copied to and from Ki Pro over the Ethernet connection. This allows for fast file transfers without the need to physically remove the media from the Ki Pro, which can be especially useful in larger facilities and can cut down on machine room traffic by eliminating the number of people that have to be in the machine room.

AJA DataCalc

Calculate your storage needs before digitizing even begins and keep your team on track.
Gatekeeper certified for OS X.

Note: the AJA Data Rate Calculator is provided as part of the system installation for all KONA cards, Io Express, and the Io HD.

Ki Pro lets you record edit-friendly HD ProRes files directly to removable KiStor Media. Once removed from the Ki Pro, the KiStor can be inserted in the AJA KiStor Dock which connects directly to your computer via Thunderbolt™ or USB3, allowing you to rapidly transfer ProRes files that are ready for use immediately in your non-linear editing system.

KiStor Modules

KiStor Storage Modules use thoroughly tested media and are backed by a 1-year warranty. KiStor Storage Modules are also engineered with the rigors of production use in mind; not only are robust housings used for the media, but connectors rated for multiple insertions and removals are used, unlike bare HDD or SSD connectors that are not engineered for repeated use. Additionally, KiStor modules can be formatted in the device making it a true stand alone recorder; connecting the media to a host computer to format media is not necessary.

More Information

KiStor Dock

This external docking station provides both Thunderbolt™ and USB 3.0 connections for ultra-fast file transfers between either PC or Mac host computer and KiStor modules. Works with all KiStor modules.


Provides a surrounding chassis for the Ki Pro that can both mount to a tripod and provide a mount for camera on top; this combination allows convenient access to controls.

Ki Pro Rod Accessory Kit

This kit adds endplates to the Exo-skeleton so you can attach two user-supplied 15mm camera accessory rods. The endplates have knobs for adjusting the height of the rod brackets relative to the camera, as well as a set of knobs for securing the rods in the brackets.
