How to use chroma optimizer with megui?

[Moti172]

Hello

Is there a way to use chroma optimizer when encoding movie with XviD via megui?

Thanks

this parameter is normally part of the zones. it seems it is not implemented in megui. thus you could define your zones manually in the custom command line:
-zones 0,w,0.5,25O/1000,w,1,O/166846,w,0.04,25OG
This is an example how zones work in xvid_encraw:
1st zone got a weight of 50%, 25 bframe sensivity & chroma optimizer (O)
2nd zone starts at frame 1000, weight 100%, chroma optimizer, (brame sensivity=0, default)
3rd zone from 166846 with weight of 4%, 25 bframe sensivity, chroma optimizer and greyscale G

there are other parameters as well: K = keyframe (zone starts with keyframe) and C for cartoon mode...
---> 166846,w,0.04,25OGKC
