96 is the best since its 2*2
Not really best. The best ratio is 3.
For 24 fps movies it will be 72 Hz mode.
x3 ratio means you will get in each 3 frames: one frame always source with maximum of quality, another two frames has time positions 33% and 66%. It is close to sources than 50% position. More close to source position gives less visible artifacts. Of course I'm talking about possible artifacts. You will never see them at source frames and in some cases at calculated frames only ![]()
