x265 [error]: uhd-bd: bit depth, chroma subsample, source picture type must be 10, 4:2:0, progressive

My guess that the problem lies with the:

--multi-pass-opt-analysis --multi-pass-opt-distortion -analysis-reuse-file "/Users/Laurent/Movies/Akira_2160p_generated.analysis"

part of the call.
-> try without those options.
