I tried this reboot the camera to PAL and back to NTSC suggestion yesterday and couldn't tell a difference. Has anyone captured video before and after switching that demonstrates the effect?
I rather suspect the issue has more to do with the ambient light level than anything else -- when there's strong lighting, the camera stack does an admirable job for what it is, in low light, it does the best it can.
Exactly my experience. Ambient light or poor light conds outside make this effect more visible.
And also I can confirm if you don't touch the sharpness setting and stay at 0, it is better till the moment you set it for -1 for the first time. Then returning to 0 doesn't(!) work. Only the soft reset of the camera can help again (no matter if you do it via "reset all camera settings" or swith to PAL/NTSC and back - the second option I see as better since it doesn't delete all cam settings, just hot-restarts the camera).
It's clear that watercolor issue is caused by heavy post-processing in the Mavic internal SW, (NR & smoothening) visible at JPGs.
E.g. look at DNGs (Adobe RAWs) they all have significant vignette (darker corners) - this is a HW limitation of poor optics. But JPGs don't have vignettes - this meens Mavic DOES a lot of processing when shooting/filming. This is also connected with the red hot spot visible at JPGs / yellow warm center area at MGPs vids - all more visible under the poor light conds. So from my point of view, SW is trying to do the best to correct HW deficiences what are (known but from the marketing point of wiew yet) hidden to public.
I also suspect a bit the Adobe influence here. DNG is their standard (e.g. Nikon doesn't use DNGs), and embding this type of processing into HW (DJI and others) producers' FW makes great connection, doesn't it? You can go and buy AdobeLightroom and get many plug-ins (patches) for vignette correction, red hot spot corrections, and more! (Available specially for Phantom 3, 4, maybe for Mavic soon). And guess what (!?) - you can get rid of all these issues at once (!) by a sipmle click "apply patch" to the batch of DNG images (works also for Mavic red-hot spot and watercolor!) - sounds like a pure miracle, what you think? :-)
