Compact Answer:
H264 uses 4x4 / 8x8 / 16x16 pixel blocks in combination with some weired picture slicing when compressing video.
So the width and height needs to be a multiple of 4.
Therefore the height the Camera uses is 6 pixel larger then perfect 16:9 ratio, resulting in a 6 pixel high band.
VLC-Player for example removes those pixels, Windows Media Player does not.
GoPros 2.7k resolution is a lil smaller and 1 pixel short of perfect 16:9, preventing the band effect.
Resize your videos to GoPros resolution in post and you should be fine.
DJI: 2720 x 1536 (pixel perfect 16:9 would be 1530 height = +6px = band at bottom)
GoPro: 2704 x 1520 (pixel perfect 16:9 would be 1521 height = -1px)
