I recently finished evaluating Beamr Video. 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, I concluded 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, Beamr Video reduced the bitrate of the test clips by 50% on average in High Quality mode, and 35% on average in Best Quality mode. From this, I concluded, “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”.
