just:in mac is a macOS-based client-server multichannel capture solution to record SDI, HDMI, NDI®, SRT, UDP, ST-2110, VTR and multicamera sources using Crash, Batch, or Schedule recording modes.

One User Interface, Multiple Channels

The built-in video and audio previews and the adaptable multichannel aware inspector enable the operator to control all available capture machines from a single user interface.

Single and Multichannel Recording

Versatile and expandable client-server multichannel recording solution aimed at 24/7 deployments in critical broadcast or post-production environments. Ability to select either CPU or hardware-accelerated encoding to overcome possible encoding limitations.

Format and Container Support

Capture video sources with growing file support into industry-standard MOV, MXF OP-1a or MP4 containers using broadcast-grade codecs, including Avid DNxHD®/HR®. Please consult the NLE vendor’s notes about codec/container growing file compatibility.

Additionally, with version 6.x, you can use HLS Format output to share recordings in real-time with external production teams or provide the HLS stream to external MAM/PAM systems for advanced logging and tracking functionalities

NDI® Formats, SRT, UDP and ST-2110 Support

Full discovery and recording support for NDI High Bandwidth/HX3, SRT, UDP, and ST-2110 format input sources to complement SDI and HDMI. just:in mac employs the latest official macOS NDI SDK to establish connections with available NDI streams within a designated network. Given the inherent characteristics of NDI technology, as well as the variability in networking configurations and infrastructure, it is important to note that the performance and integrity of all recordings might vary.

Please refer to the official NDI documentation for detailed information: https://docs.ndi.video/docs/docs/index.

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 using AJA and Blackmagic Design SDI video devices.

Capture and Event Presets

Customizable capture, destination, events, and overlay presets to quickly switch between commonly used setups, execute trigger action on third-party hardware, or apply static and dynamic custom graphic overlays. Additionally, selecting external audio sources, both local and over the network, is a welcome addition to the Capture preset setup process.

Extensive Metadata Support

The XML metadata engine enables you to customise your metadata entries, including required fields for data compliance and to export the resulting XML to related sidecar files or directly to the QuickTime file

Operational Safety First

Enjoy the ability to save and change/swap recording configurations on the fly for distinctive productions or shows to highly increase operational safety. With the new Dynamic Folder Generation feature based on Naming Presets, you can automate naming tasks to further increase operational safety.
