H.265 with D-Log results in serious banding, watch the video.

Comparison footage of DJI PHANTOM 4 PRO's camera using codecs H.265 and H.264 in D-Log.

DO NOT USE H.265 with D-Log because serious banding occurs in large areas with the same color like blue skies, etc.

ALWAYS USE H.264 for D-Log.

Tested with the latest firmware update - April 2017.
ISO Locked in 500
Style: Sharpness -1, Contrast -1, Saturation -2
GRADED with DJI's D-Log LUT

Still can't wrap my mind around why anyone uses d-log in the first place. It's a joke on the Mavic and not much better on the P4 or P4P.
