The AJA Ki Pro Quad 4K Solid State Recorder ingests raw footage from a camera, and performs up to all three of the following functions simultaneously: stores the footage to an SSD, transfers the footage to a RAID or Thunderbolt-enabled computer, and outputs the footage to up to two displays for monitoring.

Footage can be captured RAW and in 4K, Quad HD, 2K, and HD resolutions. Captured RAW, it can be transferred RAW to a RAID or computer. Color depth supported is 10-bit 4:4:4 and 10-bit 4:2:2. In cases of storing to an SSD, the Ki Pro Quad can record in 4K, 2K and HD ProRes formats, which are friendly to Final Cut, Premiere and Avid. Two SSD slots are available.

A diverse set of connections includes SDI, HDMI, balanced audio, Thunderbolt, and Ethernet. A 4-pin XLR port is also available on the bottom of the device. For monitoring, a 4K display and an HD display can be connected by dedicated SDI and HDMI monitor connectors.

The Ki Pro Quad also usefully features a playback-capable display monitor that would allow you to see what you're recording.

Multi-Function Solid State Recorder
  • Captures, records and outputs 4K, Quad HD, 2K, and HD
  • Supports 10-bit 4:4:4 and 10-bit 4:2:2 / Can capture and transfer RAW
  • Records to edit-friendly 4K, 2K, or HD ProRes files on removable SSD media
  • Features SDI, HDMI, Thunderbolt, XLR, Ethernet and balanced audio connections
Output
  • Real-time transfer of RAW to a RAID or Thunderbolt-enabled computer
  • Uncompressed and debayered output to 2 displays by dedicated SDI / HDMI connectors
Debayer Processing
  • Performs debayer processing of RAW (RAW can further be manipulated by software tools)
  • Debayered image is used for 4K monitoring, scaled/cropped HD monitoring, and on-board compressed storage to SSD media

Manageable 4K

Enables a powerful yet manageable workflow for 4K. Ki Pro Quad serves as a central gathering point for the main needs of 4K production; bring camera signals into Ki Pro Quad and then simultaneously create edit-friendly 4K ProRes files, output to 4K monitors and record RAW data directly to Thunderbolt-enabled computer/storage system. 4K content needs are growing. Ki Pro Quad helps ease the transition to 4K with a recorder that creates smaller file sizes while still retaining quality.

HD now, 4K when you need it

Supports 4:2:2 and 4:4:4 recording even at HD and 2K resolutions. Real time scaling from 4K to 2K/HD. Shoot 4K but record 2K to keep file sizes down but still have theatrical quality images to work with. HDMI output allows connection even to HD consumer monitors. Ki Pro Quad can cover your needs today and into the future.

Powerful

New hardware-based features, such as real time, high-quality RAW debayering, recording directly to 4K resolution Apple ProRes files and real time scaling from 4K to HD. Only AJA can deliver advanced features like these in such a compact package.

Affordable

Ki Pro Quad is priced substantially less than other 4K recorders but still has the power and functionality for the demands of 4K productions as well as functionality not found in recorders of ANY price.

Familiar

Ki Pro Quad follows the same tried-and-true principles that have made the rest of the Ki Pro family successful, creating high-quality, low-bandwidth ProRes files up to 4K resolutions, that can be easily offloaded to a Thunderbolt or USB 3 enabled computer via AJA's Pak Dock SSD media reader. The resolution may be different, but the process is the same. And with the same capabilities of Ki Pro Mini for remote control, automation, ease of use and mounting options, the transition to Ki Pro Quad is virtually seamless.

4K and HD Monitoring

At 4K resolution, the ability to check focus and exposure is critical. The only way to do this is with proper, full 4K monitoring. Ki Pro Quad provides a full resolution output that can be fed to 4K monitors for real time, on set quality checks. Real time hardware scaling creates high-quality HD-SDI and HDMI outputs for viewing on consumer and professional HD monitors, giving you additional options.

RAW Support

RAW data is the source from which all other image formats can be generated. This is the equivalent of a camera negative in film terms. Thunderbolt allows the bandwidth to record this RAW data via a single cable to a properly configured drive array. Ki Pro Quad supports RAW data pass-through while simultaneously recording to 4K ProRes files, for the ultimate in data security and flexibility.

Onboard confidence monitoring

The screen on the Ki Pro Quad is located on the same side as all of the user controls so that both the screen and controls are fully accessible even when the Ki Pro Quad is mounted to the camera along with other gear. This provides a quick reference of the input signal as well as the configuration menus. The current status of the Ki Pro Quad as well as all the configuration information is displayed on the built-in screen.

Small enough to mount directly on the camera

4K cameras are no longer giant pieces of machinery. They are as mobile as an HD camera and need a recording device that matches. Ki Pro Quad has the same side profile as the AJA Ki Pro Mini, so the same mounting accessories such as the Mini Mounting Plate can be used to mount the Ki Pro Quad to cameras, rails or whatever the situation calls for.
