Should we expect a solution to this problem? I must admit that the use P4 to video in 4K format does not apply!

Well, to answer that would require me to know what it is you are referring to? Please explain your problem.

Also, as it has been edited and then uploaded to Vimeo, there has been a lot of processing going on, and quality issues can only be judged from the original material. You might upload a short section of original video to demonstrate your issue to Dropbox.

Sorry, but what does this mean?

Original video (dlog  - WB sun  -  4K  -  60mb/s - 3d noise off) - [url]http://culturalseason.ru/share/DJI_0721.MOV[/url]

Please look at the artifacts in the sky.
Such problems make it impossible to shoot in 4K.

I downloaded your 44 second clip, I can't see the artifacts you refer too, at what point in the clip do you see them ?

Do you mean colour banding in the sky ? - if I look really hard there is a little but it is very minor.  You may be able to remove it by editing at a higher bit depth. To be honest I would be pretty happy with it as it is !

Nice video Oleg,

Banding issue is very usual for low bit rate footage shot in Dlog.

Best Regards,
Andrey

Very beautiful... I didn't notice anything unusual in the sky.

Friends! Digital sampling of the sky, is not treatable, but if you reduce the detail!

On Phantom 3 Pro, I did not notice these problems.
