Hey

I seem to have stumbled on a problem with aliasing I think.
I tried to apply an anti aliasing filter SAA() but it didn't quite work. If it's not aliasing, could someone tell me what it is?
Here are some screenshots of what I mean (look at jaggy edges around the red hair):

Maybe it's just with the size of the source image but I see nothing wrong. It looks quite good to my eyes.

That's what I was thinking too. But everyone says I have bad eyes, so I didn't say anything.

The source might have some verty sutle noise, but it looks ok to me as well.

There's Nothing wrong with your source :D

There are some subtle chroma artifacts from the yv12 color space, but otherwise the source is completely fine.

Hmm OK, if everyone says it's OK then it's OK. Thanks for the advice.

I can't see anything wrong with the source, apart from the fact that there is some graining.

Try using RemoveGrain, or Convolution3D...

Or even FFT3DFilter if the above two won't help. If you decide to use FFT3D you might have to end up using some sharpening afterwards (I recommend aWarpSharp).
