Is it possible to drop some specific frames when comparing SSIM by ffmpeg?
Use the select filter to drop unwanted frames.
This is the basic syntax:
ffmpeg -i distorted -i ref -filter_complex &quot;[0]settb=AVTB,setpts=N[ds];[1]settb=AVTB,select='not(eq(n\,3)+eq(n\,717))',setpts=N[rf];[ds][rf]ssim&quot; -f null -
