Applying Quality Encoding Metrics For 2D And VR Video

Description: Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the streams. However, by measuring stream quality with metrics such as CRF, PSNR, Spherical PSNR, Weighted Spherical PSNR, and VMAF, you can assess the quality delivered…

Join Me in Las Vegas at NAB

Just a quick note to let you know that I’ll be speaking twice at NAB in Las Vegas next week; once as host of a panel discussion on HEVC and AV1, the other a session on how to use objective quality metrics to assist encoding configurations. Details are below. If you’re at NAB and free,…
