Questions about this product?
  • Simultaneous 4-Channel 1080p60 Recording
  • 1-Ch DCI/UHD 4K/2K/HD Recording/Playback

  • Infinite Record, Forced Rollover Options

The AJA Ki Pro Ultra Plus Multichannel Recorder offers four channels of simultaneous recording in up to 1080p60/50, along with single channel recording and playback of DCI 4K, Ultra HD 4K, 2K, and HD signals. This AJA recorder gives you four 3G-SDI inputs and one HDMI input, as well as the same number of outputs. It also supports optional fiber modules for extended distances.

Firmware update 5.0 features an Infinite Record function that enables continuous capture and rollover from drive to drive. It also improves RS-422 timecode operation, NDF timecode for DNxHD files, gang compatibility, and 2SI input/output.

Recording to ProRes codecs up to ProRes 4444 and to Avid DNxHD, and offering familiar VTR-style front panel controls, the Ki Pro Ultra Plus is simple to use and records to robust, edit-ready formats. It records to optional AJA Pak Media SSDs. Two AJA Pak slots are available and allow for rollover recording without dropping frames.

Ki Pro Ultra Plus has a 4.8", 720p LCD screen that delivers a clear playback image. Dual redundant 4-pin XLR power inputs provide you with security against accidental power loss. One power supply is included.

Ki Pro Ultra Plus can be used desktop-mounted or installed in a 2 RU rack. It has a half-rack width, and two units fit in a single compatible rack shelf, sold separately. It also has a handle on top for easy transport.

Note: The Ki Pro Ultra Plus recording inputs must be genlocked together, or multichannel recording and monitoring failures may occur.

Multi-Channel HD Recording

Record 1, 2, 3, or 4 channels of HD up to 1080p60/50 in Apple ProRes simultaneously. Simplify your multi-camera productions by running up to four cameras, and save power, space, time, and effort on set, in the studio, and when setting up OB trucks.

Ki Pro Ultra Plus even allows independent profile support per channel in Multichannel mode. Select high-resolution Apple ProRes HQ for high-quality finishing and use a second input to record ProRes (proxy) for an efficient editing pipeline.

Starting with input 1, add channels as needed in order when utilizing like raster sizes and frame rates, and record your HD Apple ProRes files on the same AJA Pak media, sold separately. (Pak Media 1000 modules with an -R0 module designation and all Pak Media modules with -R1 designations are supported for multichannel recording.) Ki Pro Ultra Plus even allows rollover to a second Pak for hours of uninterrupted multichannel recording.
