I had a similar problem with my first run. The software does not have a user control to slow down the drone and the camera appears to be on automatic.
My test run was done months ago and it was early in the day and overcast and the drone was traveling at over 20 mph and when I looked at the images, they were not crisp. I love detail and this was less than desirable for that particular use.
Now I have a use more in line with what I believe the software was designed for and the updated firmware and software is preventing the camera from taking a test shot (that is another thread’s topic).
I have been a professional photographer in the past and to override this problem, I limit my shooting sessions to bright sunny days and when the Sun is high.
When doing this, the camera will have to use a faster shutter speed and smaller aperture and that will give you the best quality shots possible. I assume that you are using the fastest memory card available as that can also limit the camera’s ability to keep up with the drone.
