JPEG XS is a professional image and video codec designed specifically for workflows where high image quality and ultra-low latency are essential. Unlike traditional distribution codecs, JPEG XS does not aim for maximum compression, but rather for visually lossless quality with low complexity and low latency.

This makes JPEG XS particularly suitable for live production, broadcast, remote production, and professional AV-over-IP workflows. Compared to uncompressed video, the reduced data rate lowers network bandwidth requirements while maintaining high quality and responsiveness.

Key benefits of JPEG XS:

• Ultra-low latency
• Visually lossless image quality
• Lower bandwidth requirements than uncompressed video
• Low computational complexity
• Ideal for professional IP-based production workflows

Fraunhofer IIS is one of the key developers of JPEG XS and contributed significantly to its standardization within the ISO/IEC JPEG committee. Get more information at https://www.iis.fraunhofer.de/audio.

joinXS supports professional JPEG XS workflows from live production and recording to review, archiving, and post-production. The applications can be used individually or combined to create an end-to-end JPEG XS workflow.

Typical use cases include:

• Live Production & Broadcast: Recording JPEG XS streams directly from IP-based production environments
• Sports & Entertainment: Recording and quickly reusing high-quality live content, for example for highlights or post-event content
• Remote Production: Integrating JPEG XS into distributed and IP-based production workflows
• Recording & Archiving: Recording JPEG XS streams into MXF files for direct storage and later reuse
• Review: Quickly playing back and reviewing JPEG XS content stored in MXF files
• Post-Production: Importing and exporting JPEG XS media in Adobe Premiere Pro for editing and further processing

With joinXS Recorder, Player, and Premiere Plugin, JPEG XS content can be used across different stages of the production workflow without first having to convert it to another media format.

 
With the free demo editions of the joinXS applications almost all functionalities of the full versions can be tested. However, there are the following restrictions:

joinXS Recorder

• Watermark visible in the live preview
• Recording time limited to 30 seconds

joinXS Player

• Watermark visible in the decoded image
• Reduced quality after 30 seconds of playback

joinXS Premiere Plugin

• Embedded Watermark during import (decode) and export (encode)
• Decoding in reduced resolution after 30 seconds of playback

No dedicated JPEG XS hardware is required to use joinXS. The applications are software-based and run on compatible standard Windows and macOS systems.

The hardware you need depends on your specific workflow and the characteristics of the JPEG XS stream or MXF file, particularly resolution, frame rate, and data rate. joinXS itself does not impose a fixed resolution limit.

For typical 2K workflows, we recommend the following as a general guideline:

Windows

• Intel Core i5 12th generation or newer, or equivalent AMD CPU
• 8 GB RAM
• Windows 11 or later
• 1 Gbit network connection for joinXS Recorder

macOS

• Apple M2 or newer
• 8 GB RAM
• macOS 15 or later
• 1 Gbit network connection for joinXS Recorder

Higher resolutions and more demanding workflows may require more powerful hardware and higher network bandwidth.

As actual performance depends on your individual setup and content, we recommend testing joinXS in demo mode with your own system and typical JPEG XS content.
