Ki Pro Ultra Plus is a Multi-Channel Apple ProRes® recorder offering up to 4-Channels of simultaneous HD recording, or in Single Channel mode a 4K/UltraHD/2K/HD Apple ProRes, Avid DNxHR, or Avid DNxHD® MXF recorder and player supporting the latest connectivity including 3G-SDI, Fiber and HDMI 2.0.

New v3.0 firmware offers HDR playback support for HLG and HDR10, as well as HDR recording for HDR10 and HDR10+.

Designed to be both portable with a built-in carry handle or rackmountable with half rack wide 2RU high dimensions, Ki Pro Ultra Plus suits a wide range of production and post environments.

Key Features

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 Multi-Channel 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 utilising 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 multi-channel recording.) Ki Pro Ultra Plus even allows rollover to a second Pak for hours of uninterrupted multi-channel recording.

Edit-Ready, Independent ProRes Files
Multi-channel recording with Ki Pro Ultra Plus provides individual, discrete recordings for each input that are timecode-accurate and ready to be imported directly into a multi-channel editing sequence. No additional conversion or software is required. Just drag and drop the files directly from the Pak media into your edit. The clip naming convention is yours to customise to suit your needs, but each multi-channel file is always appended with .1, .2, .3, or .4, making it very easy to track assets in post.

Continuous Record and Rollover, Even in Multi-Channel Mode
Losing one or even several feeds during a multi-channel shoot can cause major sync issues during the editing process that can be lengthy to resolve, if they can be resolved at all. But Ki Pro Ultra Plus is designed so that as soon as a loss in signal is detected on any of the inputs, a colour bar frame with the legend "Loss of Signal" is recorded until the input is restored or the shoot ends. In this way, all multi-channel clips have the same timecode duration and will align perfectly within any NLE. The editor then just simply cuts away from any recording that lost signal, without any heavy lifting to insert frames, or adjust audio to compensate. This function works with each input to Ki Pro Ultra Plus and will even function in Rollover mode, meaning that a loss of signal that spans separate media will pose no issues in editing, the timecode of each file recorded being equal.

Ki Protect
Ki Pro Ultra Plus includes Ki Protect, a feature that helps to 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 to be recorded when the operation was interrupted. Frames that are already recorded will be preserved and are recoverable, providing greater peace-of-mind on set and in the studio, essential for multi-channel recording.

HDMI 2.0 - One Cable, Multiple Formats
Full HDMI 2.0 support offers deep colour support all the way up to 4:4:4, 12-bit RGB, perfect for rich colour capture from affordable HDMI cameras and beautiful playback on the latest HDMI 2.0 displays.

A single cable can affordably transport both Ultra HD or HD video and clean 24-bit, 48 Hz 8-channel audio to or from common HDMI 2.0 devices for a simple setup; perfect for independent producers, editors, ProAV, and anyone seeking to utilise the latest affordable capture and monitoring tools.

4K, 12-Bit Full Raster Workflows
Next generation DCI 4K/Ultra HD 4K at 50/60p recording and playback are attainable all the way up to Apple ProRes HQ when using optional AJA Pak1000 SSD media with Ki Pro Ultra Plus.

DCI/Ultra HD is supported through 4 x 3G-SDI, HDMI 2.0, or optional fibre inputs and outputs.

Ki Pro Ultra Plus not only supports true 4K at 4096 x 2160p for digital cinema and high-quality Ultra HD for broadcast production, it also offers the colour depth to match.

Any shoot or project benefits from the fabulously rich colours and smooth gradations across the luminance and chroma range that 12-bit makes possible with full 4:4:4 support, including Apple ProRes 4444 XQ.

VFX work benefits from Ki Pro Ultra Plus' 12-bit support on 4 x 3G-SDI inputs to captured Apple ProRes 444 files, resulting in clean green screen plates across the DCI/Ultra HD/2K/HD raster landscape for easy and detailed post-production manipulation. With full HDMI 2.0, you can monitor it all from 4:2:2 YCbCr to full 4:4:4 RGB in 12-bit.

ProRes 422 and 444 Recording
Ki Pro Ultra Plus records DCI/Ultra HD/2K/HD to six quality levels of Apple ProRes, including Apple ProRes 4444 XQ. This lets you choose the balance of image fidelity and file size that's right for each individual production as well as having the flexibility to record directly to native file formats that are understood by most major editing systems.

Next generation DCI/Ultra HD 60p recording is attainable all the way up to Apple ProRes HQ when using optional AJA Pak1000, or AJA Pak512-R1 and Pak256-R1 SSD media.

By utilising Apple ProRes, your project will have the best image quality available, with manageable and affordable file sizes.

Avid DNxHD MXF Recording
Ki Pro Ultra Plus offers native Avid MXF support for HD workflows. Record and playback DNxHD files with an OP1a profile within an MXF container for DNxHD HQX (220x), DNxHD SQ (145) and DNxHD LB (36) codecs. This provides a native MXF workflow for Avid pipelines, free of transcoding.

exFAT and HFS+ Support
Ki Pro Ultra Plus allows you to use the file system that suits your needs. Full flexibility is provided to format your recording media as either exFAT or HFS+ within Ki Pro Ultra Plus itself or from your desktop computer, ensuring wide OS compatability.

2SI (Two Sample Interleave)
Ki Pro Ultra Plus supports both Square Division Quad Split format and Two Sample Interleave giving a wide number of options to both record and playback DCI and Ultra HD.

Set up is easy, with Ki Pro Ultra Plus sensing the format being delivered in its "Follow Input" mode. Ki Pro Ultra Plus also allows you to select separate quad modes for both in and out, giving an additional conversion feature for when you need it.

Up to 64-Channels of Audio
Ki Pro Ultra Plus offers up to 16-channels of audio support embedded over SDI or optional fibre per input, bringing a total of 64 channels of high-quality recording. Flexible routing options mean that 8-channel only outputs like HDMI, analogue, and digital carry options for selecting the 8-channel group required. Monitoring via the headphone jack on the front of the unit is split into easy 2-channel groupings by input for on-set cheques.

Closed Caption Support
If you need to record or play out video with Closed Captioning embedded, Ki Pro Ultra Plus is fully compatible with your needs. Ki Pro Ultra Plus recognises CEA-708 within incoming SDI inputs and encodes the Closed Captioning to your Apple ProRes recorded file. Upon playback, you can utilise the Closed Captioning within a recorded file over Ki Pro Ultra Plus' 4 x 3G-SDI outputs.

Reliable Storage Media
Ki Pro Ultra Plus captures directly to rugged and reliable AJA Pak SSD media, sold separately. Pak media is available in a variety of capacities to best suit the demands of your production.

Pak1000 is the ideal companion for Ki Pro Ultra Plus, offering 1TB of fast SSD media for up to 4K recording at 60p in ProRes HQ. Pak512-R1 and Pak256-R1 models offer equal performance in smaller capacities when needed.

The twin media drive bays on the Ki Pro Ultra Plus allow extremely fast media changes and rollover recording even for multi-channel recording, which allows a recording to start on one media module and seamlessly continue onto the second module once the first has reached capacity.

Pak media may also be used with the optional Pak Dock, which features USB 3.0 and Thunderbolt connectors for lightning-fast data transfers from and to your desktop or laptop.

Pak-Adapt-eSATA, sold separately, is a Pak Media-sized adapter with an eSATA connector that allows you to attach a qualified RAID or single volume storage via an eSATA cable so that it may be used as a recordable drive. eSATA connectivity provides the bandwidth needed for 4K 4:2:2 HQ at up to 30 fps. You can even connect two Pak-Adapt-eSATAs to the Ki Pro Ultra Plus for more flexibility in the field.

Note: Multi-channel mode on the Ki Pro Ultra Plus is not supported by Pak-Adapt-eSATA.
