Its definitely faster for me as smothhiq was, now a yv12 tempsmoother and im totally happy..
BTW it does work fine in qmf, i just jumped to conclusions too fast. :)
1) Are the radius (radiuses? radii?) higher than 4 really broken? I've tested 5 and 6 which use a different processing, and I couldn't see any problem where I would have expected them.
If you are talking of the fact radius higher than 7 can't be selected, then this is intended. I don't plan to had radius 7 (that's already a 15x15 kernel) because it's too much hassle for the benefit over radius 6, and it would only be used for that very case.
2) I wrote on my page that it was a simplistic remake of smartsmoother. I've added a part which makes it of higher quality but not HiQ :)
if you properly read the page once again, you'll see the booleans HQY and HQC activate the hiqh quality mode for respectively Y channel and U,V channels. To go deeper into details, it almost works like msmooth: it calculates a local edge value for the current pixel and plane processed, and decrease accordingly the weigh of the smartsmoothed pixel. That leads us to the parameter "strength": the higher it is, the more you'll keep the smartsmoothed version and keep the original. This strength is dynamically modified by edge value in HQ mode: the higher the edge, the less the smartsmoother pixel will be used. The current setting makes it worth for anime I bet, as it is very sensitive to edge:
new strength = input strength - 4*edge value
Check by yourself how the HQ mode changes the output (strength isn't used in none-HQ mode).
3) tempsmoother? Like the one in the old mpeg2dec? temporalsoften isn't sufficient ?
