just:in linux is an enterprise-grade, client-server-based ingest solution for multichannel recording from SDI, HDMI, NDI®, and SRT input sources. It unites the power of a macOS client frontend with the scalability of a Linux-based backend.

Multichannel HD / UHD Recording

Sophisticated and workflow-oriented multichannel ingest in one flexible, expandable and enterprise-grade client-server ingest solution. Support for SDI, HDMI, NDI® and SRT sources to be recorded independently or concurrently, including proxy file creation.


just:in linux enables 24/7 deployment in time-sensitive broadcast environments and comes with an internal RAID for reliable and sustainable recording.

Operational Safety First

Use multiple destinations for out-of-storage or network connection loss scenarios, and enjoy the ability to save and change/swap recording configurations on the fly for distinctive productions or shows to increase operational safety.

One User Interface, Multiple Channels

The built-in video and audio previews as well as the flexible channel inspector enable full control of all available ingest machines from a single user interface. Different multi-viewer layout templates can be defined and selected based on specific user login.

Multimode and Multiframerate Support

Ability to mix and match HD or UHD channel formats with different video modes, formats, and frame rates for different channels.

Full HDR and Rec.2020 UHD Support

Full HDR metadata support (with HLG and PQ transfer characteristics) for Apple ProRes 422 HQ/MOV recording workflows for AJA video devices.

Extensive Metadata and Adobe Markers Support

Enhanced Integration Flexibility

Boost your integration potential by using the extended REST API, or flexible Event Presets to perform different recording or notification tasks and control qualified hardware devices, and finally benefit from a redesigned and seamless integration with the iconik Media Management and Collaboration platform.
