I made this video last night and edit the footage on DJI Go App, so the image quality is not clear, or the problem is the lens?

Love to see someone there with Mavic and where I lived for over twenty years.
It seems your Mavic is out of focus.

The DJI editor is crap as it edits the cached 720p file and not the actual higher quality file on the SD card of the mavic.
Also, you need use manual focus and guess. Or use autofocus without AFC (focus hunt). Now set the ISO high as you can and set the shutter to long exposure. Now the dark areas will be lit up for you to lock a focus. Now set the iso down to 100 and nominate 24fps (lower FPS = more light entering the lens) and don't touch the screen otherwise it will refocus and blue again.

I will try that, thank you for your suggestion QuanthonyTrang.
