A recent consulting project involved computing the VMAF, SSIM, and PSNR scores of 30 fps 480p video encoded from a 60 fps 1080p source file.

How many devices will play AV1 without some form of …

Number of hours of streaming required to recoup 60-minute encoding cost.  Author’s note: The author would like to acknowledge the shocking fact that he is not perfect and that this lack of perfection often reveals itself, quite embarrassingly, in spreadsheet-intensive articles. I did the best I could and checked every number and assumption multiple times, but if something doesn’t look right, …
