The R1 2024 release brings major updates to Composer, including improved workflow, new components, improved chroma keyers, support for ProRes files (including 4:4:4), and more. We have also added downloadable Tutorials and Demos that might become valuable when evaluating Composer or learning about new features.

R1 2024 also supports the new Extended Monitoring plugin. This optional add-on provides advanced, centralized monitoring for large-scale setups.

News and Improvements:

  • Overall performance increased by reducing CPU load by 5-10%.
  • UHD and 4K capture performance can be up to twice as fast as in previous versions using the new optimized Blackmagic Capture.
  • Added support for 8K video processing (7680x4320).
  • Add a new target: FFmpeg Target. This generic target allows you to use any FFmpeg command to send/write audio/video to any destination supported by FFmpeg.
  • Added a new operator: Crop Operator
  • HSV Keyer:
    • Added support for using a clean plate instead of a specific hue, saturation, or value.

    • Added support for adjusting the hue tolerance.
    • Added support for Spill balance for all types of spill suppression.
    • Added support for Spill balance automatic Calibration. 
    • Added support for picking the key color directly from the operator (without using the color picker tool).
  • Media input improvements:
    • Added support for importing Prores 10-bit 422 files (.mov)
    • Added support for importing Prores 12-bit 4444 files (.mov). This is an important improvement as it allows HQ files that include Alpha Channel to be imported into Composer.
    • Added support for pixel format 10-bit AV_PIX_FMT_YUV422P10LE. Applies to h264, h265 (HEVC), and Prores file formats.
    • Added support for pixel format 12-bit AV_PIX_FMT_YUVA444P12LE. This applies to the Prores (.mov) file format.
    • Reduced memory consumption for QuickTime Animation files
    • Removed the need for adjusting the buffer length
  • Added HostName to log file entries and metrics    
  • Added a command line tool, cavconverter, that can be used for creating CAV-files with embedded cue points. Find more information in the documentation.
  • BlackMagic Capture: Added support for Decklink input channels 9-16.
  • NDI input: added support for configuring the error level (error or warning )being logged if a connection is lost. 
  • RTMP-target has been optimized and does not render any load when disconnected.
  • PerformanceLog: added maxProcessingTime to log
  • Added support for fetching a performance report via the HTTP API: /api/reports/getperformancereport
  • Improved performance for the BlackMagic Capture V3 input. Activate the by selecting Use Pinned Memory.  
  • A new optimized target for Blackmagic Decklink cards: Blackmagic Target V3. It supports Windows and Linux OS and requires less processing time than the previous version (V2). We recommend that all customers upgrade from V2 to V3.
  • Added support for pushing logs to Loki. https://grafana.com/go/webinar/getting-started-with-logging-and-grafana-loki
  • FFmpegTarget: Added support to log frame details from FFmpeg. Example: name= MyFFmpegTarget frame=  928 fps= 23 q=27.0 size=   13568kB time=00:00:39.63 bitrate=2804.2kbits/s speed=   1x  

  • Desktop version
    • Added support for downloading Tutorial- and Demo projects. This new feature is available in the main menu. 
    • Added support for re-ordering inputs in the inputs list by using drag-and-drop.
    • Added GPU utilization metrics, including NVENC Encoder, NVDEC Decoder, power management, and power usage. It might require an update of your Nvidia drivers.

      • Added support to Reset position, Reset Scale, and Scale to fit context menus.
      • Added support to lock Scale X and Scale Y.
      • Added support for panel scroller.
