HDR

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 X3 provides this support for your 2K and HD HDR pipelines to HDMI and SDI compatible displays in software v16.2 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 X3 adds 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 X3 Plus also provides 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 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.

v16.2 Desktop Software also offers HDR input from HDMI for capturing HDR gaming content and more.

Use Case: NLE Workflow for Io X3

Io X3 offers broad support for all major NLE applications, including Apple Final Cut Pro, Avid Media Composer and Adobe Premiere Pro with a host of practical and easy to use features, shown in this NLE workflow diagram. The Io X3 sits at the center of the NLE workflow, connected directly to the host laptop via super fast Thunderbolt 3. The NLE software is running on the host laptop, with the output of the time line being shown via both the HDMI port and the 3G-SDI port simultaneously, with support for HDR and SDR monitoring. The analog audio jack on the front of the unit provides easy headphone monitoring, whilst at the same time a standard Tascam DB-25 loom connects an analog mixer and microphone to the workflow, with the front panel VU meters responding to the independent channel levels. An AJA Ki Pro Ultra 12G is connected for real time recording of the NLE output to Apple ProRes or Avid DNxHD codecs for archive or hand-off. Whether editing promos, news footage, sports, long form content or any other demanding video environment content, Io X3 is your perfect partner.

Use Case: OBS Workflow for
Io X3

Io X3 is directly compatible with OBS Studio, offering a comprehensive toolkit for mixing live video and taking the program content out to streaming destinations. Io X3 again sits at the center of the workflow pictured opposite, providing the necessary video I/O for a 4 camera source program. Via Io X3's multi-channel support, the 4 HD cameras are connected directly to the 3G-SDI ports of the Io X3 which is connected via Thunderbolt 3 to the host PC or laptop. The host computer runs the OBS Studio software and allows you to view all incoming HD sources in a single multiview via the HDMI port to any display. Audio can be monitored via the built-in analog headphone port. The final PGM stream is output from our switched sources via the host computer.

Use Case: Streaming Timeline Workflow for Io X3

A popular way to stream for NLE and 3D modelling applications is to utilize the timeline output and offer commentary in real time as edits or models are created. Following the same base set up as the NLE workflow and by utilizing AJA’s HD streaming device, the HELO, we can combine two high quality AJA devices to create an extremely robust solution. It is easy to connect a 3G-SDI output from the Io X3 to the 3G-SDI input of the HELO and take the content directly from the timeline playhead to a live stream, with voiceover provided by a USB microphone. A very simple but powerful set up that can be utilized by streaming for both entertainment, remote collaboration and educational purposes, allowing viewers to better contextualize the content.

Use Case: Video and Key Workflow for Io X3

Io X3 fully supports video and key workflows up to HD 60p as shown in the adjacent diagram. The first instance shows Io X3 connected to a laptop or desktop computer running Ross Xpression software. The Xpression software is receiving live statistics and weather data as metadata via the internet. It is also receiving two live IP video inputs. The IP video is assigned as video 1 and video 2 out with the incoming statistics and weather metadata assigned as key 1 and key 2 out. Io X3 provides an HDMI out for multiview of all four sources on one monitor. The Io X3 can then pass the groups of video and key 1 and video and key 2 via 3G-SDI onto a router or other SDI destination. The second diagram also shows the same set up but this time all inputs are IP video sources that are assigned in Ross Xpression as video and key 1 and video and key 2, with the Io X3 again providing multiview monitoring via HDMI, whilst simultaneously passing the video and key pairs out via 3G-SDI to a router or other SDI destination.

Integrated Digital Audio,
Analog Audio Flexibility

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

Stereo monitoring is also possible with a front panel 3.5mm mini-TRS headphone jack.

The flexible analog audio I/O can be configured to record voice overs and more with the ability to choose how the DB-25 connection on Io X3 is configured:

  • 8-channel, 24 and 16-bit D/A analog audio, 48 kHz sample rate, balanced, using industry standard 8x XLR or TRS 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

High Density, Rack Mountable

Io X3's compact design offers easy rack mounting, allowing for two Io X3 devices to sit comfortably in just 1RU. This allows for high channel density for up to 8-channels of fully configurable video I/O for applications such as OBS Studio.

Multiview Output

Io X3 offers multi-channel I/O, and the HDMI output port can display all of these sources to one display. Io X3 is fully compatible with OBS Studio software with multiview output offered for clear monitoring of incoming or outgoing video via the convenient HDMI output. OBS Studio can be configured with Io X3 to make monitoring easy, all from a single I/O device.

Sync Up

Io X3 can be locked to an external reference for integration into larger productions, or feed LTC in and out to ensure footage captured with Io X3 has the proper timecode. The REF in port ensures reference sync with other synched devices in a facility.

Machine Control

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


Apple M1 Chip Support

Desktop Software v16.1 and above is optimized for the Apple M1 chip with native support for AJA macOS drivers, application plug-ins, AJA Control Room, AJA Control Panel, AJA System Test and AJA NMOS software.
