Might want to take a look at my thread in this sub-forum on conservation of HDR10 info. I was mainly talking about handbrake and DaVinci Resolve to begin with but realized all I really needed was the correct ffmpeg/x265 commands and then learn how to apply those settings in staxrip. It won't tell you everything you need to know but one thing you may or may not already know about HDR is that you have to check each source file for its max-cll (max-cll and FALL are done in the same variable) and make sure your luminance values are correct and that you are using the correct 'master-display' parameters (P3 or BT2020, P3 is most common but still its worth checking). So a lot more work goes into running a batch encode of HDR content than SDR as each files HDR specs have to be incorporated into the encoding command, unless they have the same max-cll and luminance and master-display I suppose.
Here is a link to that thread so you don't have to find it yourself:
