Io 4K

4K and HD I/O for Thunderbolt™ 2

Io 4K is the next evolution of capture and output hardware offering a full set of professional video and audio connectivity with support for the latest 4K and UltraHD devices and High Frame Rate workflows. The power of Thunderbolt 2 enables Io 4K to handle a wide range of formats from SD to HD, UHD and full 4K over both SDI and HDMI and support 4K frame rates up to 50p/60p.

Professional connectivity

Io 4K has the connectivity required for today’s variety of productions. With full-sized BNC connectors for 4K input and output as well as HDMI in and out, Io 4K can handle professional 4 x SDI 4K signals as well as capturing and outputting 4K over HDMI for use with more affordable 4K equipment.

Futureproof

With more affordable high-resolution cameras available, many productions are opting to shoot at a higher resolution even if final delivery is still in SD or HD. This offers the flexibility to re-master at higher resolutions in the future.

Io 4K can support your current SD and HD workflows and provides a path to move to higher resolution productions and also higher frame rate support whenever the need arises. The realtime downconverter also means you can work at higher resolutions and easily create lower resolution deliverables without the need to recapture or re-edit. All at a size that’s small enough to easily take on-set or in the field.

Monitor 4K in HD

When working at 4K resolutions, Io 4K outputs a high-quality HD-SDI down-converted signal on a dedicated BNC connector. This HD signal can be used to output 4K projects directly to HD recorders for broadcast and for easy viewing of 4K images on HD monitors during post-production.

Powerful

Thunderbolt 2 technology provides an incredible amount of bandwidth on a single Thunderbolt cable. Io 4K capitalizes on this increased capacity to allow up to 4K signals at frame rates up to 50p/60p to be captured and output.

With dual Thunderbolt 2 ports, Io 4K can daisy chain additional devices together such as high-resolution displays and high-capacity storage for a complete, portable solution that’s powerful enough to meet the demands of professional production.

Integrated Audio

Embedded 16-channel SDI and 8-channel HDMI audio are supported as well as analog audio outputs via a standard DB-25 connection. Stereo monitoring is also possible with 2 x RCA outputs and a front panel mini-TRS headphone jack.

 

AJA hardware conversion

Io 4K features full 10-bit, broadcast-quality, motion adaptive SD to HD up-conversion, HD to HD cross-conversion, HD to SD down-conversion, and automatic HD/SD 12-bit component analog output. Since all conversion functionality is hardware-based, it's available on ingest or playback.

Sync up

Io 4K can be locked to an external reference for integration into larger productions, or feed LTC in and out to ensure footage captured with Io 4K has the proper timecode.

Machine control

An RS-422 port allows control of tape decks for frame-accurate captures and layoffs.


Extensive software support

AJA hardware is supported by an extensive list of professional software for editing, visual effects, graphics and more allowing the same AJA device to be used by many different applications on the same system. In addition, AJA provides several free applications that enable you to utilize the power of your AJA hardware even without having to run a particular software package. This allows you to create unique workflows without tying up valuable resources unnecessarily.
