AJA Control Room Metadata Toolset

Metadata is the key for managing advanced workflows. AJA is bringing to market an entirely new way to harvest metadata in the SDI signal stream and export the metadata to a sidecar file.

This new feature, called AJA Control Room Metadata Toolset, is being introduced in Desktop Software v17.1 and adds the following functionality:

  • Supports capture of any metadata type, including SCTE-104 and Dolby Vision metadata, that is part of the SDI Ancillary metadata payload.

  • Using an AJA KONA capture card that supports SDI input and the included AJA Control Room software (such as KONA 5 or KONA X), the card captures the metadata, which is then preserved in a metadata sidecar file.

  • AJA Control Room can playback the metadata to provide quality monitoring.

  • AJA Control Room can export the metadata synchronized with the media on a per-frame basis.

AJA Control Room’s interface focuses on the task at hand without adding unnecessary clutter. Intuitive controls are instantly recognizable, keyboard shortcuts and context sensitive menus streamline actions, layouts can be customized, and user presets saved, making it fast and easy to get your work done.

Create Bins, capture uncompressed video or choose from a range of compression options. Once captured, files can be simply played out through AJA hardware to professional SDI or HDMI devices/destinations, depending upon your choice of AJA I/O hardware.

Full Screen Playback and System Audio Support

AJA Control Room can be used as a free stand-alone professional media player, even on systems without any AJA hardware attached or installed.

When used without AJA hardware, video can be monitored full-screen using the host system GUI, and audio can be monitored with any internal or attached speakers.

Flexible Workflows

AJA Control Room feels, looks, and works the same whether your sources and deliverables are files, live feeds, or tape. With the same intuitive interface available on macOS, Windows, and Linux, teams can feel comfortable when they need to capture, monitor, or output media, with the same features, controls and layout are available on whatever system they are working on. AJA Control Panel, which is AJA Control Room’s companion application for configuring your AJA hardware, extends the flexibility and speed for even the most complex and challenging workflows.

Work with 8K, UltraHD2, 4K, UltraHD, 2K, HD, and SD resolutions plus a full range of uncompressed and compressed file formats at your disposal, including read/write support for H.264 and H.265, Avid DNxHD/R, plus the entire Apple ProRes family including ProRes 4444 XQ, and many more.

AJA Control Room software supports 12-bit, 10-bit, 8-bit YCbCr and RGB workflows, plus the industry standard RS-422 interface allows capture and playout to VTRs with frame accurate control.

Unlock the next generation power of 8K capture and playback via KONA 5 and use a more cost effective workstation. For example, capture 8K ProRes and use the file immediately in your NLE or other application of choice.

4K Closed Captioning Support

AJA Control Room software now supports ingest and playback of 4K content that carries Closed Captioning when using a KONA 5, KONA 4, Io 4K Plus, or T-TAP Pro.


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.

HDR workflows can also benefit from AJA's Control Room application and its companion, AJA Control Panel, which comes complete which has built-in HDR test patterns.

AJA Control Room also provides VPID signaling for SDR/HDR Transfer Characteristics, Colorimetry, and Luminance transfer characteristics over SDI, bringing flexible output options to your AJA device. 

AJA Control Room can also feed HDMI HDR displays, offering HLG and HDR10 support with HDR Infoframe metadata in accordance with HDMI 2.0a/CTA-861.G, for compatible KONA, Io, and T-TAP products. HDMI ports that were already HDR compatible will work simultaneously, for HDR output via both SDI and HDMI.

AJA Control Room software further offers 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.
