[marcorocchini]

Hi c*t

please how to little sharp (more detail) picture using ffmpeg?

and avisynth? thanks

p.s but my source is interlace

[pandy]

I use :

smartblur=lr=2.00:ls=-0.90:lt=-5.0:cr=0.5:cs=1.0:ct=1.5

- video need to be deinterlaced first.

[marcorocchini]

ah thanks

[marcorocchini]

but sorry is not a plugin for avisynth?

[pandy]

nope, this is ffmpeg filter - for avisynth exist plenty of filters where sharpen can be applied.

As a general rule I don't like video that "looks sharpened", and sharpened noise looks terrible, so I apply it sparingly, but if I do sharpen it's pretty much always with LSFMod.

I find the defaults work fine although I usually reduce the sharpening strength (50 to 75 rather than the default of 100). Personal taste. You'd need to de-interlace first. Try QTGMC followed by LSFMod.
