AJA Io 4K Plus Capture Card

AJA Desktop Software is optimized for the latest Apple silicon with native support for AJA macOS drivers, application plug-ins, AJA Control Room, AJA Control Panel, and AJA System Test.

Io 4K Plus is compatible with Apple Mac Pro systems and supports AJA Control Room with Metal, along with a broad range of professional creative applications. For productions handling high-resolution workflows all the way up to 4K, Io 4K Plus is a perfect companion with the Mac Pro Thunderbolt 12G-SDI and HDMI 2.0 capture and playback.

AJA Control Room

• Supports CEA-608 or 608-in-708 via ANC extraction firmware

Avid & Adobe Plugins

• All SMPTE-291 (ANC) based captions supported

• Avid Media Composer supports active video ANC (line 21) or ANC via ANC extractor/inserter (up to UHD/4K)

Simple to set up and use, Io 4K Plus' Thunderbolt ports easily connect to a wide range of Apple, Windows, and Linux laptops and desktops, providing instant professional video and audio output from your favorite creative application. 

Dual Thunderbolt ports allow convenient daisy-chaining of Thunderbolt devices. 

Thunderbolt is widely supported by Mac, Windows, and Linux computers and supports the massive bandwidth needed for professional video, audio, data, and more. 

Thunderbolt Solutions 

HDR or High Dynamic Range, provides the ability to display a wider and richer range of colors, much brighter whites, and much deeper, darker blacks than standard signals allow. This gives your imagery a more ‘dynamic’ look and allows for natural, true to life colors to be communicated to your audience.

Io 4K Plus provides this support for your 4K/UltraHD/2K and HD HDR pipelines to HDMI and SDI compatible displays, with HLG and HDR10 support with HDR Infoframe metadata, in accordance with HDMI 2.0a/CTA-861.3 and HD.

AJA Control Room software and Io 4K Plus add support for HDR metadata capture from an incoming SDI or HDMI signal. The captured .mov video file will have embedded HDR metadata, allowing the file to be played back at its intended dynamic range.

AJA Control Room software and Io 4K Plus also provide HDR Auto Playback Detection. Embedded HDR metadata in a recorded .mov file, is read and used to automatically set the HDR format on the monitor(s) connected to the AJA HDMI and/or SDI outputs.

Support for file-based .mov HDR outputs with metadata from Adobe Premiere Pro / Adobe Media Encoder HDR files is also available. Screening those rendered outputs is a simple and high-quality experience with AJA Control Room. Every frame is presented in its full-quality, at the timing intended, and with the proper HDR format set correctly and automatically.

AJA Desktop Software also offers HDR input from HDMI 2.0 for capturing HDR gaming content from PlayStation 5 and PlayStation 5 Pro and more.

Embedded 16-channel SDI and 8-channel HDMI audio are supported, as well as, analog audio inputs, outputs, or both via a standard DB-25 connection.

Stereo monitoring is also possible with a front panel mini-TRS headphone jack.

With AJA Desktop software analog audio can be configured for flexibility when needing to record voiceovers and more with the ability to choose how the DB-25 connection on Io 4K Plus is configured:

• 8-channel, 24 and 16-bit D/A analog audio, 48 kHz sample rate, balanced, using industry standard 8x XLR on DB-25 breakout cable (cable not included)
• Balanced Analog Audio I/O:
  • Input across Ch. 1-8, Ch. 1-4, or Ch. 5-8
  • Output across Ch. 1-8, Ch. 1-4, or Ch. 5-8

Capture real time footage with Io 4K Plus over SDI from high quality cameras, meld your footage with your virtual environment created by the Unreal Engine and send it back out in real time to air, a growing need for broadcasters, augmented reality (AR) needs and more.

Digital filmmakers also benefit from these new workflows: On-set, enhance your live action VFX work with the ability to see a full composite live during the course of the shoot. This results in fewer reshoots, and the ability for actors to understand the virtual environment they are working within for stronger performances and ultimately leads to a range of efficiencies and cost savings with the added benefit of a smoother transition into postproduction.
