...and to conclude, I think you've reached the limitations of the camera on the Mavic. Low light is the problem as most daylight footage filmed with the Mavic isn't just good, its great, when you consider the amount of tech you get crammed into the overall cost of the Mavic drone. Higher ISO settings will help for the examples you have posted but this will introduce grain.
You are not understaiding my point. Of course I know the Mavic's camera limitations, and I still love the quality of it and it's amazing what this small sensor can do, the images it produces are great. Obviously I'm not expecting its small camera to shoot RAW video, and yes, I'm a photographer and videographer and I have studied image formats, compression, bitrate, codecs, etc and I know how they work. My point is that due to the internal image processing of the Mavic when sharpness is in a negative value the shadows get software-defocused. This is clearly a bug, man, there's no camera out there that does that. By setting the sharpness at -3 we should be getting a less processed image with less artifact and noise, and not so tack-sharp. As shown, the sensor is capable of seeing the detail, so why is it messing things up post-processing? As I said, you can shoot with positive sharpness and get the detail in those dark areas, just because the sensor is capable of seeing it, the downside is the artifacts and noise you get because of this digital sharpening effect. In the image I'm posting below (taken from a 4k video I took) you can clearly see that the top part of the mountain is sharp and the shadowed part is all messed up and blurry. Why is that? Why can't we get the detail? The border of the lake, the small road and the areas with contrast/well exposed have sharpness, while the dark areas are blurry. I don't think I'm being so exagerated about this, I really think it's a bug and that it could be easily corrected, and I expect someone on this forum to try it for themselves and see if it happens to them. |
