Hi, <br><br>how does the PSNR calculation of x264 work when i use e.g. --video-filter resize:width=320,height=240 to encode a 1920x1080 video to 320x240? Does it scale the encoded frame up to 1920x1080 or does it scale the original frame down to 320x240 for the PSNR calculation? And which interpolation filter is used for the rescaling in the PSNR calculation? <br>
<br>Thanks for help!<br>Mullius<br>
