I had a X5S early on but sold it when we migrated to the X7. Prior to PRR I pretty much only shot CDNG along with some 4444XQ. I don't do a lot of post but I do enough that I don't like the CDNG workflow. I prefer ProRes. But was disappointed that it was only 10 bit. On this topic I figured the X5S wouldn't be different- and especially not better than the X7 in terms of encoding. Looking at the X5S specs on the DJI site they don't have an equivalent chart that shows bit depth like the X7 page does. Unfortunate but like you said, DJI documentation has a lot of inconstancies. It does mention 12 bit for RAW specifically, tho.
I joined this forum because I have a
M3C on order. I'm still waiting for it to be delivered. I look forward to doing some tests between it and the output of the X7. I know they will be different but as long as the log ProRes footage even somewhat matches the level of detail and dynamic range the X7 provides it will be pretty exciting.
Also, Netvise, thanks for documenting the test.
