Yesterday, I flew my Mavic Pro and shot video, with the camera set to 4K. When I downloaded the video from the SD card, I was disappointed to see what looked like very low resolution, not even HD. Today I tested it, shooting short videos with the drone in my hand, and the resolution was fine. Any ideas?

When I owned the MP I found that the focus could be off a little which obviously gave the footage a very soft feel and looked like a low res. Always ensure everything is fully focused and setting the sharpness to +1 helped too - though I am going back a few years now.
