Hello,
How to use x264 lossless setting?
how can I do this?
I already tried -qp0 parameter in the encoder options but that didn't work.
Which container settings should I choose?
please help me, thanks all

Choose the font ffmpeg and "CRF leave blank" delete any number, (not even 0, does not work.) Be aware that lossless the final file will be huge. Check out Task mode: "Normal". Choose a container that matches the decoder and video format to avoid errors.
Last but not least, let profile and level in auto.
