The Rithm Advantage

Rithm uses AI driven content-adaptive encoding (CAE), to automatically sense how “difficult” each video is to encode and adapts the encoding algorithms to ensure the highest quality and lowest bitrate video. Rithm combines two patented AI technologies: Signal-Adaptive Bit Rate Estimation (SABRE) and Perceptual Quality Optimization (PQO).

SABRE dynamically sets the bitrate for each segment. The technology looks at all the frames in a video segment and uses an AI model to determine the necessary bitrate to achieve the desired mean opinion score, or quality level, in that segment. SABRE AI models are based on visual perception data gathered from human subjects, not simple mathematical functions.

PQO dynamically sets the bitrate for each frame, assigning more bits to the most perceptually important areas of a frame. It uses a human visual AI model to determine where within a frame additional data is needed to make visually stunning video.

Rithm results in higher quality video and a 15% to 75% bitrate savings.

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?
