Usually I always use dewarp function during filming on DJI MFT 15mm due to big lens distortion (fisheye) on footage.

But I notice the next thing - dewarp will not affect on video recordered in 422/4444 codec, only on H.264.
(check attached files - the same shot, but you can see how is different the horizont in terms of distorion).

Is it my drone failure or it is normal?

No it's normal.

The camera doesn't apply the correction to Prores or RAW recording.

To fix in PP just add 10% of lens curvature in the Lens Distortion effect  -  Job done.

I agreed with 2#. Our engineers are working on that. Please wait patiently for next firmware.

Any news on this?
