Hi, I am based in the US but am not able to select 30fps in full 4k resolution.

3840x2160 works for 24/30fps but not 4096x2160. Am I doing something wrong?

THanks

3840x2160 is considered 4K UHD (Ultra High Definition) and is the resolution we mean when we say “4K” because that is the most common 4K resolution.


As @Keule has pointed out 4096x2160 is called Cinema 4k or C4K. Cinema 4k also has a frame rate requirement. It has to be in, you guessed it, 24 FPS!

The reason it is called “Cinema 4K” is because the Digital Cinema Initiatives, LLC (a.k.a. DCI) mandates that this is the resolution required for all projectors in movie theaters across the country and thus the resolution movies have to be delivered in to the Cinemas from the Movie studio.

4096x2160 comes from the fact that movies were previously required to be in 2048x1080 (1080p) and so older movies can easily be upscaled to 4096x2160 on these newer projectors. The DCI also mandates acceptable frame rates for motion pictures. 24 FPS for 4096x2160 and 24 or 48 for 2048 x 1080 (which then needs to be up scaled to 4096x2160 by the projector.

The DCI was created to set standards for cinemas and movie studios to maximize interoperability between movie formats and cinema projectors. Imagine the chaos if the projectors in a cinema in Independence, MO where unable to play movies in 30 FPS, or projectors in Spokane, KS could only play movies in 1080p. Movie studios would have to render movies in different file formats and frame rates to accommodate the various cinema’s capabilities costing everybody more money and confusion.



However, this may be a poor excuse for why the Mavic Pro cannot record 30 FPS in 4096x2160 since it already has multiple resolutions and frame rate options that aren’t DCI compliant. The better answer is the MP can only record video at a maximum 60 mbps which is roughly 3840x2160 at 30p or 4096x2160 at 24p. 4096x2160 at 30p would exceed the operational limits of the Mavic Pro.

And so hopefully you haven’t fallen asleep by now. I guess I have too much time on my hands these days

Haha, thanks for the detailed and quick response. Stay healthy

Excellent albeit complex explanation. I followed every word. We have to realize these little cameras are just tiny computers with lens and as such, have operational limitations that are being improved regularly but there are factors that limit higher specs. These limitations are being improved yearly. It wasn't too long ago drone cameras weren’t even HD.
patience Grasshopper!

Thank you. Nice technical history lesson. I have a Mavic Pro and normally only shoot in 1080 for my real estate clients. Some want 4K video, but that is a small number overall.
