Topic: what is better for SVP? Blurred or sharped source?

Sometimes I apply filters to the image.

If I apply filters after SVP the cpu usage is higher than applied before.

1) If I apply filters before SVP... how I could get max smoothness? having a blurred image or having a sharper one?

2) What about noise and blocks? Its better leave them or filter them before SVP?

edit: Im replying myself to questio 1)
A blurred or very blurred image moves smoother than a shap or very sharp one...

I wonder if there is any process active into SVP that is pre-sharpening image in certain way... I would want to deactivate it to gain smoothness

1) sharper is better.
2) filtered from noise and deblocked source is better.

No

Why you think blurred is better? What source you used for tests?

Hi MAG79 wink
Im testing with the classic "test video avatar". If I apply extreme blur, the image moves smoother ... if I apply extreme sharp.. seem to be very complicated for SVP and the smoothness is partially destroyed.

(Im using 8px grid and shaders by blocks). I have to check other configs

Where do you find your "test video avatar"?

You can use one of 3 avatar test clips from SVPmark (SVPmark\data\video\ folder).
