Ghosting effect vs settings

Hello everyone,

I'm having fun with x265 for a few days now. Depending on the scenes which occur in the encoded material ghosting is barely visible and other times it's quite tragic. My question is quite simple. Which switches have most impact on ghosting effects? (Which switches should I play with?). Are there any switches that have very significant impact on it and should be avoided?

TIA

--psy-rd

Ghosting in x265 is primarily due to the effect of high psy settings, result in some blocks coded skipped. You can lower down the psy-rd values to ~1.0, but then you are probably unhappy with the blurring effect.
--constrained-intra should help some as well/

also, are you using a 1.9 build? That has a new psy-rd that should do this less.

It would be helpful if you could share your whole command line.
