Thanks

I cant remember right now, but I think you have to start it from your command line (Programs->Accessoires->commandline, use "cd yourfolder" to go to the folder where the program is...)
Then type psnr4avi, and it should tell you what you have to do...
I think the usage is just "psnr4avi movie1.avi movie2.avi, but I'm not sure right now...

avisynth (version 2.5x I guess) also includes a compare function which can give you PSNR values. Geverally, if you wanna compare 2 avi files in Y
clip1 = avisource(blablabla.avi).ConvertToYUY2
clip2 = avisource(etc.avi).ConvertToYUY2
compare(clip1, clip2, "Y","PSNR.log")
More infomations about this compare function can be found in avisynth help files.
Good luck!:)

It's been awhile but IIRC it works better when you redirect the output to a file so it doesn't scroll away:


psnr4avi movie1.avi movie2.avi >somefile.txt
