I need to measure streaming video from various different codecs and be able to tell which one is better.

What will be the best metrics to look for?

Is there a free tool that can help with this.


There are a number of comparison algorithms available beginning with PSNR through SSIM/SSIMPLUS to VMAF. VMAF is implemented as an ffmpeg filter.

  • Thanks Michael, kindly can you please also suggest a free tool that can help in the process. Thank you

  • @user75464, what do you mean "help in the process?" I'd already suggested ffmpeg as it is able to run the VMAF algorithm. Are you looking to do something else? Sep 30 '19 at 17:50
