Don't know what 100% crop is, but it is known that this drone has a problem with fast motion and surfaces like grass or gravel. Not sure if this problem is related to encoder, sensor or both, but since DJI is ignoring these topics I think that it is well known to them and not fixable. Only thing you can do in these circumstances is to use ND filters to convert this noisy mess into more acceptable blurry video.
"but it is known that this drone has a problem with fast motion and surfaces like grass or gravel."
Partly true. ALL the DJI drones have this problem. The OP has shot footage of a close-up vertical shot while flying quickly aver a grass lawn. No matter what camera you use (outside of pro cinema cameras), you will get a poor result from this type of shot. The maximum bit-rate of the camera is 100 Mb/s, which is too low to capture fast changing images like that. DJI could implement a faster bit-rate, but then you would not be able to use standard off-the-shelf SD cards to record the images. It would require expensive CFast cards or mini-SSD drives, and there is a space and weight penalty to using those devices.
The solution is to recognise the limitations of the camera and shoot accordingly. Avoid fast movement and scenes with excessive high detail. Fast movement over fine detail overloads the MPEG encoding processor, if you look at the end of that shot, it looks fine as soon as the fly-over ends.
