Rithm Optimizes Processing to Maximize Bandwidth Savings and Quality

With 10+ years of pioneering academic research and development, the Rithm AI-based cloud transcoder offers best-in-class compression technology adaptable to any workflow. Rithm uses content-adapative encoding (CAE) to deliver:

  • The highest quality at the lowest bandwidth
  • Faster start times and less buffering
  • Reduced network and storage costs

Rithm optimizes a video’s bitrate during pre-encoding for a desired quality level on a per-segment basis. Quality is measured using subjective test data for an accurate model of the video.

Additionally, Rithm’s enhanced encoding uses AI to mimic the human visual system and to adapt the bitrate based on the complexity frame by frame. In the picture the areas in red are more perceptually noticeable to people and fewer bits are allocated to the less noticeable parts.

 

Rithm in Action

The videos shown here are 1080p fully compliant H.264 bitstreams encoded with Rithm. Prior to encoding, a maximum allowable encoding bitrate or “standard” bitrate is specified, and a quality level is chosen to balance bitrate savings and encoding quality. Rithm determines the lowest bitrate that maintains the chosen quality level and results in both significant bandwidth savings and high-quality encoding for all of these videos!

Take the Rithm Challenge

One of the two videos sharing the split screen below uses 32% less bandwidth than the other side. Can you tell which side is more compressed?
