Recording Media / Removable Storage

Record with Ki Pak SSD cards in the (2) media slots on the front of the AJA Ki Pro Ultra. Pak1000 is the ideal companion for Ki Pro Ultra as it offers 1TB of fast SSD media for up to 4K recording at 60p in ProRes HQ. Ki Pro Ultra also offers compatibility with Pak256 and Pak512 media, ideal for lower frame rate projetcs.

The Kai Pro Ultra supports Pak-Adapt-eSATA and Pak-Adapt-CFast with AJA qualified media only.

The twin media drive bays on the Ki Pro Ultra allow extremely fast media changes and rollover recording. You can start recording 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. 

exFAT and HFS+ Support

Ki Pro Ultra 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 itself or from your desktop computer, ensuring wide OS compatability.

Ki Protect

Ki Pro Ultra 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.

2SI (Two Sample Interleave)

Ki Pro Ultra supports both Square Division Quad Split format and Two Sample Interleave giving a wide number of options to both record and playback 4K and UltraHD.

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

16-Channel Audio Support

Ki Pro Ultra provides full 16-Channel audio support embedded over SDI or Fiber. Flexible routing options mean that 8-Channel only outputs such as HDMI, Analog, 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 for location checks.

Closed Caption Support

If you need to record or playout video with Closed Captioning embedded (CEA-708, CEA-608), Ki Pro Ultra is fully compatible with your needs.

Ki Pro Ultra recognizes CEA-708 within incoming SDI Inputs and encodes the Closed Captioning to your Apple ProRes recorded file. Upon playback, you can utilize the Closed Captioning within a recorded file over Ki Pro Ultra's (4) 3G-SDI outputs.

Built-in LCD with Onscreen Intuitive User Interface

Ki Pro Ultra features a beautiful, high resolution HD display for pristine monitoring of your material. The LCD screen serves as your interface to Ki Pro's familiar and intuitive menu system. The detailed overlay UI includes onscreen keyboard functionality and a clear view of the powerful yet simple to operate UI, all pristinely presented on the 4.8" 720p LCD display (1280 x 720).
