Avisynth: Sharpening without making blocks noticeable?
 

is there any filter that can sharpen my movies without making blocks and noise more noticeable.

I'm asking this because i am encoding my movie at 352x240 and it looks very soft/blurry.

i don't want to increase the resolution by to much because i want to keep the file size low.

The source resolution is 576x304.

Thanks in advance

Hi muhali3,

If you are using the MA optimal script, you can change the line that reads:
asharp(1, 4)
To:
asharp(2, 4) or to asharp(3, 4)

That will increase the sharpness of the picture.
Even if you are not using the MA script, you can still add that filter, and use it as above.

Is it best to sharpen first before smoothing or after?

Yes, because if you smooth before sharpenning, there's nothing to sharpen :)

Just my 2 cents here:

I made the experience that it is not worth it to go for a lower resolution and sharpen the picture, rather than going for a higher resolution and soften it. what I mean is : if you want to get more sharpness, simply go for a higher resolution, because filesize will get bigger too if you use a higher sharpening value, and the results might not please you. at least they don't please me. :wink:

yes Jell, really right!
:wink:

i did the same:
was 352x480 with "sharp" and got the (round) same size and
little more quality with 480x480 without "sharp".
of course, don't know if i will get the same
from differents movies with differents final times!
only the tests will show!
