MED600X3D - need transcoding on a couple of cases

Hi all…
Use Serviio long time ago and now just took a MED600X3D.
I need to use them together for a couple of cases…
MED600X3D reads almost everything I tested so, basically, I want access Serviio from MED600X3D, just to read RAW photos and everything 4K related.
For that, I know I need a profile that I guess will not be much complicated, but I’m not reaching there…
Given the MED600X3D deals very well with Full HD, just need transcode RAW photos and 4K related files to a format that not “loose” more quality than the necessary to make it compatible.
Can someone help me, please?
Thank you very much…
