Hey guys,

I've been going all out lately experimening with diffrent players and Renders zo get the best quality possible. And I thought that I finally did it with the KMPlayer (the 1432 R2-Release) when I turned on my PC and checked Lucky Star in xvid.

Whilst color quality, sharpness and whatnot is pretty much on par with the pc's output, the lines on the characters edges are much smoother than on the pc. Weird enough it looks exactly the same on ps 3 as on pc when I fast forward or rewind on the ps3?! Is there some Cell-Postprocessing magic going on, or can I get the same resoult on pc aswell?

I attached the picture of the pc output (lanczos resize (luma&chroma sharpen to 80, paramter 2) to 1360*768 and then downscaled to 1280*800 [looks virtually the same when not downscaled, I just couldn't be bothered to hook up the HDTV]); now look at the lines around the hair and clothes. It's quite noticable actually that they are a bit jaggy/fuzzy, whilst on ps3 they look very smooth and sharp. (can't capture a frame from there, I'm afraid)

If you guys need a sample vid, please let me know.

For now I'd like to thank you very much for any eventual help :) :thanks:

Edit: Oh, and I have Postprocessing at max in ffdshow; I understand that unsharpens the picutre a bit, but even turning it all of wouldn't solve this 'problem'.

Edit2: Through further testing it seems to have to do something with the Parameter voice in the scaling options; any idea what they stand for and what I should set there? Parameter 1 makes it even worse, yet Parameter 0 almost perfect; Parameter 10 is perfect but seems to oversharp the thing, I'm kind of lost... ^^'

I can't see your picture, but anyhow run KMPlayer in highspeed/superspeed modes and output RGB32HQ from ffdshow.

that's the only way to avoid chroma upsampling bugs :

On which renderer was this sample? I haven't seen such errors in any newer drivers.

EVR/VMR9, same problem.

this is with the 8.x ATI drivers, they make crappy RGB conversion.

I think it's the same with nvidia.
