Hello Guys!
I am quite new to videography with my drone, and I need some advice on my footage. On youtube I have seen many beautiful shots using the mavic. Most of them was on +1 sharpness. I have tried the same settings and for me the result seems terrible... The footage has lots of noise? and grain?. On -1 it is much nicer. I have created a video with 3 example shots (about 15 second each) The first is I think the most terrible. The sun is on the front . Settings: +1 -3 -3. The second is in the golden hour, sun is shining from the back. Settings: +1 -3 -3. The last one is from the same spot as the second. Sun is from behing but the settings: -1 -3 -3. The result is much nicer I think, BUT I am loosing much sharpnes and details. Every shot was taken in 4K What do you think?

Your sensor is not very capable to capture great video in bad light conditions.
Especially  sharpnes +1 reveals noise because the Mavic is not performing noise reduction.
That is actually a very good thing, because your computer is far better with improving video quality than a little chip inside of your Mavic.
Choose sharpness 0 or -1 if your do want your Mavic to do noise reduction and accept blurred spots in your video and loss of details.
I advise your to do the same as the people of who you have seen these sharp and clear video's, use neatvideo or other noise reduction plugin and use a good noise profile specific for the sensor of the Mavic(easy to do yourself) and a place were the sun always shines.
I use settings +1/-1/0.
