Carbon Supports a vast array of acquisition, editing, broadcast, web, and mobile formats

Powered by Harmonic’s Rhozet® technology, ProMedia® Carbon is a file-based transcoding solution that facilitates the conversion of media to a massive array of acquisition, editing, broadcast, web and mobile formats. ProMedia Carbon supports all major SD and HD formats, and can handle all critical transcoding operations, including SD/HD conversion, PAL/NTSC conversion, logo insertion, color space conversion, color correction, closed captions extraction and more. An open API allows for the creation of custom workflows or third-party applications, further extending ProMedia Carbon’s industry-leading flexibility.

Breadth of Format Support

ProMedia Carbon can transcode from virtually any media format to every media standard in use today, and is continually updated to accommodate new formats.

Intuitive User Interface

Users can configure the system to convert a single file into any number of target formats, each with a unique set of operations and filters applied.

Scalable Transcoding

Multiple nodes can be configured as a transcoding farm, managing job distribution, prioritization, load balancing, and status monitoring.

Automated Operation

Automatic detection of the source format and intelligent transcoding to the desired destination formats increases productivity.



  • Broad format support is ideal for multiscreen content delivery
  • Intuitive user interface increases productivity
  • Scalable transcoding allows system to function as a standalone application or as part of a multi-node rendering farm
  • Automation through WFS with watch folders or WFS API

Cinnafilm Plugins for Carbon

Cinnafilm is the gold standard for file-based standards/format conversion with every major broadcaster adopting and using them daily.  Two, GPU-based plug-ins are available for the ProMedia Carbon system, Tachyon and Dark Energy, and these plug-ins will transform your PMC instance into a high quality solution for your file delivery requirements.


  • Tachyon:  Automated format/framerate/standards conversion for both straight forward and “nightmare” mixed-mode source material
  • Dark Energy:  Automated, Image Texture Aware, image-scaling solution that creates stunning HD and UHD images from SD and HD (respectively) sources.
  • Automatic noise reduction
  • Phase correlation-based, motion compensation engine
  • Temporal noise reduction
  • Spatial noise reduction with mix-back function
  • Dustbusting (Automatic, 70% effective)
  • Image sharpening
  • Logarithmic transfer space
  • Motion compensation
  • Frame synthesis to preserve natural motion
  • Format and standards conversion up to 4K
  • High quality de-interlacing
  • Interlace aware up/down rescaling
  • Inverse telecine
  • Multiple telecine pattern insertion
  • Gamma adjustment

Who We Serve


ProMedia Carbon is used to convert from the format provided by the Content Delivery Network to formats needed within the broadcast facility. Content from the server can be converted directly to a playout format, or first be converted into an editing format. After editing, the finished program is then converted again for broadcast playout.


In a webcasting environment, ProMedia Carbon is used to capture content directly from tape or DVD and then to convert it into a master digital format for storage in the archive. This provides maximum quality and flexibility for conversion to web formats. Content is pulled from the archive as needed, transcoded into multiple final delivery formats, and then pushed to the web server.
