x264 is still sharp  |
Choice of a correct screenshot this big art.
Two screenshots from the same example.
SIF1
x264
It is not enough 1 megabit for this example. And for X264 too.
For an example.
x264 Shows HD quality
SIF1 Too
In any case the codec with quarter-pel motion compensation will always show the big sharpness, than the codec with half-pel motion compensation.
Therefore I suggest to use Spline64Resize which adds sharpnesses in a picture.
At compression with acceptable bitrate the difference not so is great especially on HD.
In any case, sooner or later in SIF1 too there will be quarter-pel motion compensation.
