Green hue after convert to x265

[Bluedraft]

Hi,

Every time I convert a video to x265 I get a green tint /hue on the output picture, no matter if I use staxrip, handbrake or shutter encoder. it's notorious no matter if I play the output file with vlc, potplayer or mpc-hc with madvr, mpcvr or in auto mode, in my monitor or in the TV through HDMI, that's why I think that it's a encoder issue or something that I'm not doing right.

here is a sample, see the whites in the shirt

X265

Any idea how to fix it in order to get the exact same color in the output file.

Thanks in advance for any help.

BT.601 vs. BT.709? Post your source mediainfo, script, and encode mediainfo.

Yeah, it is subtle enough to be either a 601 to 709 conversion issue, or perhaps a PAL<>NTSC 601 conversion issue.
