Using the perceptual qualities of the human visual system, Beamr has developed a one-of-a-kind content adaptive technology that maximizes quality and removes redundancies.
At the heart of Beamr’s patented optimization technology is a unique perceptual quality measure, developed during 6 years of intensive research.
Beamr’s patented perceptual quality measure demonstrates significantly higher correlation with subjective results than any other existing quality measures such as PSNR and SSIM.
The correlation of Beamr’s quality measure with subjective results has been proven in user testing according to the strict requirements of the ITU BT.500 standard for image quality testing.
Beamr’s closed-loop technology applies several compression levels to each video frame, and for each level, compares the subjective quality of input and output frames.
When the frame quality falls within an acceptable quality threshold, Beamr Video outputs the frame and moves on to the next frame, ensuring each frame is encoded using the minimum number of bits, while fully preserving original quality.
Beamr Video controls standard H.264 and HEVC encoders, helping the encoders make smarter decisions based on true visual quality.
Beamr’s optimization process sets compression parameters per frame, guaranteeing optimal bitrate for any given content. Scenes with high motion and detailed textures get higher bitrates, while scenes with low motion and smooth surfaces get lower bitrates.
Beamr’s optimization technology reduces the overall average bitrate of the entire video title, while preserving the input stream’s quality on a frame-by-frame basis. This is not possible with fixed ABR recipes, since all video titles are encoded with the same set of resolutions and bitrates, regardless of their content.
Beamr Video optimizes files so that their bitrate is reduced precisely to fit their content. Beamr’s optimization technology delivers up to 25% bitrate reduction for action movies and up to 50% for non-action content.
