I gave the same parameters in JM and intel ipp and intel ipp beats JM in all the parameters i measured (in terms of psnr, mse and ssim).
1. Could some one please give me one good reason as to why is the intel compiler almost 500 times faster , and better than JM output. What is making the compiler special ? Is motion estimation done in a different way in this encoder ?
2. what is this parameter " speed/quality grade [0,3] (0-maximum speed, 3-maximum quality) " all about ? what parameters are set to default when
a. 0,0 ( maximum speed, min quality ) is selected
b. 3,0 ( minimum speed , max quality ) is selected Regards, Suchethan
