If I can only produce or output in 8 bit, should I just stop recording in 10 bit? Or do I gain something still by recording in 10 bit even though I have to down convert to 8 bit?
I always like to record in the best setting my cameras offer, especially if it's stuff I plan to keep, family, friends, .... so on. Can't ever go back and capture again, software and playback will usually catch up eventually. Who knows, 10 bit produce might even be supported in PD17 when released within a few weeks most likely.

So if I encode or produce in HEVC, are you saying that I can lower the bit rate to half of the Mbps (100) I recorded in and still maintain the same quality? Im a bit confused as I recorded at 100Mbps which was the rate of HEVC on the DJI Mavic 2 pro which is supposed to be half of H.264. Im thinking that the downsize already occured in the recording rate of HEVC and that I should produce at the same 100Mbps to keep things equivelent.
As mentioned, I'd always record at the best the camera has to offer. Down sampling during video production of high quality source video usually results in better quality than recording at the same levels. Between H.264 and H.265, the bitrate reduction is really unique to each individual on what their eyes sees as the same quality. It also depends on playback equipment and type of video content too. Often that break point for most is about 60% of the bitrate. This thread and a few users perspectives of quality might be of interest

100Mbps H.264 will be the same files size as 100Mbps H.265, the difference will be the user perceived playback quality.
