Jan Ozer, one of the world’s top experts on video compression and streaming and Contributing Editor of Streaming Media Magazine, has done a thorough evaluation of Beamr Video using test clips that he encoded. The evaluation included analyzing the quality of the resulting clips using objective measures such as PSNR, SSIM and VQM, and conducting extensive viewing of the optimized clips, assessing their subjective quality compared to the original clips. Following this evaluation, Jan Ozer concludes that “for 99.99% of the expert and average viewers, the Beamr-processed clips would be perceptually identical to their source”.
As for bitrate reduction, Jan has found that Beamr Video was able to reduce the bitrate of his test clips by 50% on average in High Quality mode, and 35% on average in Best Quality mode. Providing such significant bitrate reduction, while producing video clips that are perceptually identical to the source, brings Jan to the following conclusion: “If you’re spending big dollars on bandwidth, Beamr represents an opportunity to reduce it significantly, essentially delivering the benefit of HEVC/VP9 without the implementation hassles”.
Jan Ozer has worked in digital video since 1990, and is the author of over 20 books on video compression, editing and production, which have been adopted as textbooks by multiple colleges and universities. As Contributing Editor at Streaming Media Magazine, Jan has reviewed most cloud, enterprise and desktop encoding tools, and has worked with many online video platforms (OVPs) and live streaming services.
