Weird lined blocks

[Jaska]

Hello and sorry if there is already topic from this and it has already been answered. I'm just bad at searching specific stuff :\

Avisynth is causing weird darklined blocks appear on some solid areas. on the ground for example.
Here's the source (http://img.photobucket.com/albums/v288/Jakeli/source.png)
and heres the encoded (http://img.photobucket.com/albums/v288/Jakeli/encoded.png) video, even without any of the filters previewing the avisynth output looks like that

Source is old rip in rmvb format.

E: Forgot to ask if there's a filter to remove that blocking or is it issue with realmedia files or avisynth itself?

That is pretty much guaranteed to be a problem with the encoder/decoder you are using /separate/ from avisynth, not avisynth itself. In this case that encoder would almost certainly be x264. This is an x264 issue, or a decoding issue try a different decoder, if you can, if that doesn't work, take it to the mpeg4-avc/h.264 section of the forums.

Considering how mild the artifacts are, there is a good chance that it's just a weird manifestation of block transform + gradient = bad. nothing to be done about that accept throw lots of bitrate at the problem and hope it goes away, or start messing with 10bit encoding.

Thank you for your answer :thanks:

I thought it would be some common problem with clear answer ;)

I'm using x264 10-bit encoder. I Probably need to test around a bit to find the culprit that causes those blocks. Maybe from realmedia format to some lossless and check if the same thing happens, then its the decoder.
