4096 x 2160p vs 3840x2160
grejak:
Recently i have upgraded my camera gear just for stock, and i have noticed that when i upload 4096 resolution the buyers get option for full HD in bigger resolution than 1920x1080. my question is, is it worth uploading 4096 or stick to UHD? Thanks

With 4K DCI you get a bit more horizontal pixels which in theory, in numbers, is better.
You see your HD resolution change because the aspect ratio you record is 16:10, not 16:9.
This means that if someone needs to fit your video, regardless of resolution, to a UHD or HD project, he will probably crop some pixels. Maybe you need to shoot a bit wider to cover this possibility.
Almost the same is valid if you are using Super 35 mm mode.
Also, check if you record exactly 24 fps instead of 23,976.
Just a thought to conclude: Since 4K DCI is considered cinema mode and probably records at higher bitrate, you might benefit in stock from that if you shoot content that might fit a documentary or film production.

May i ask you what is the difference between 24fps and 23,976 thanks for the help !

23.976 = 24 - 0.1%
The frame rate standard has been slightly adjusted, long ago, when NTSC was launched.
Engineers noticed that color was interfering with the black and white information. The reduction of the framerate by 0.1% was tolerated by the existing black and white TV systems and addressed the interference.
Similarly, 29.97fps = 30fps - 0.1%
