This shot has been taken with MA. First, I thought it's caused by rear diode, so I did turn in off. When I'm recording, whole aircraft is dark, but problem persist (just led's on battery are on). What could be a problem? Please be sure to play it in 4k or better, download the file. There is a blink every two seconds. Newest FW installed.

looks like a combination of exposure compensation + LED is reflecting into the sensor..fireworks can put alot of smoke into the air..

you said you turned of front LEDs ?  i know the rear LED flashes and blinks...you can't turn that off i dont think..i  f enough smoke in the air from fireworks it may cause it to reflect around itself.. maybe try again on a clear night without fireworks or anything in tha air?

You can turn off both, front and rear LEDs and so I did. Firework is far...far away, so definitely there is no smoke around + it's on all my dark/night shots.

Yes, it is a great little addition on the Mavic Air to be able to switch off both front and rear LED's - you can't do that on the MP. What was your ISO, shutter speed and exposure value?

Low light conditions can cause flicker effects in the footage. See what your comparison looks like. Change the settings to gauge the impact of different shutter speeds and ISO too though try to keep the ISO at 400 or less to help prevent noise in the footage. The smaller sensors are not the best for night flights.
