@VictorLS,

Yes the files from the FX6 are large as they are not only 10-Bit, 4:2:2, UHD, 50fps, with HLG, but are all I frame AVC. Great for editing.

Here is a screen shot of DXVA Checker (is that what you want?). - https://behome.dyndns.info/index.php/s/9Q2n7XFRH6Qb3HR

I've tried (common) combinations of HEVC vs AVC / 10-Bit vs 8-Bit / 4:4:4 vs 4:2:2 vs 4:2:0 with the different LAV decoding options coupled with madVR with HDR. Apart from 4:2:0 the rest don't kick in HW Acceleration (including your sample). The "closest" alternative if I want to keep higher chroma sub-sampling and have HDR, is to encode in the same AVC-I (or Long GOP) 10bit 4:2:2 profile but converting the HLG to PQ. This will use SW Decoding, with madVR then doing the HDR processing and it will play just fine on my i7-9900K / RX3090 but my HTPC use older i5's and the SW decoding maxes these boxs out. Anyway, here is the PQ version of the sample file. https://behome.dyndns.info/index.php/s/Sfp8XJESWB8xfdB

Here is what I'm using to mux the fist two Mono Audio channels in the MXF container to MXV with the Video untouched.
ffmpeg -i input.mxf -map 0:0 -c:v copy -filter_complex "[0:1][0:2] amerge=inputs=2" -c:a pcm_s16le output.mkv
