Guys, just need to know this, My old Mavic P shoots video at 4k24 frames and the newer one at 4k30 frames. How come the difference in frames, could this be the reason why the newer one has better videos compared to the older Mavic Pro or does it not make much of a difference

The Mavic Pro can shoot in 24, 25 and 30 fps at 4K - so I'm not quite sure what you mean?


EDIT: ah, you're referring to 4096x2160 vs 3840x2160

The quality of the video footage does not only depend on the frames per second!

Yes, at 4096x2160 the older one shoots at 24fps and the newer one at 30fps, would you know why

Okay, why would the 2 same drones have different fps on 4k

So, there are two parts to this...

1. Why does the Mavic Pro only give a 24p option for at "full 4K"... probably a limitation of the image/video processing at the time, it's really hard to know unless DJI state why.

2. Newer drones supporting more frame rate options or higher bitrates is easier to explain, the chips they use are faster and more power efficient.

In the case of the Mavic 2 Pro, it's taking more information from a bigger sensor (20mpix, 10bit) and processing that into more complex formats (H.265) at higher bitrates (100mbits).

But a better comparison is the Mavic Air, which appears to use the same sensor as the Mavic Pro but is backed by a newer, more powerful image/video processing which give better results.

Check the camera settings PAL or NTSC.

I think ardvark, May have the answer, to your other question, orignal Mavic Pro was dogged with Camera problems, and firmware helped a lot , and this is pretty standard with all dji drones.

Will check that

In PAL you will get 24p and 25p in c.4K. In NTSC you will get only 24p - c4K is designed for cinematic video. c.4K @ 30p is new to me on the MP.

Yes 30fps in the US 24 Europe and I presume SA,  same with 60fps in US ntsc, 50 FPS Europe or pal,

Reason for this is basically half  the hertz output , in US 60 htz the NTSC, in Europe 50 htz Pal, so all your Telly’s in SA if running Pal your correct video for viewing should be 24 fps. It’s just the way we are used to watching on our screens.

So that is correct, I was using my iphone when flying this yesterday and it has a FCC hack on it, today I flew it with my Samsung which has the latest firmware and no hack it showed 4k24fps

Yes but in the hack, you should be able to change from ntsc to pal, in order to view on pal system then watching 24fps should be much more what we pal users are used to.

well Suren my friend I am quite satisfied with my videos with my MP,  people who view these videos are always remarking how crisp and clear the videos are, for that reason I am satisfied and stick with the MP unless of course I happen to win the lottery.

The whole NTSC Vs PAL goes back to the analogue days of the BBC. I use NTSC in the UK and enjoy 30p with no problems as all of my devices are digital.

The framerate has very little influence on the image quality.
Lens, sensor and processor do most of that part.

It amazing there are so many confused about framrates , so many think that somehow if you shoot in 30fps that you will have better image, not the case.
Higher frame rates don’t make better images.

The only thing that might benefit from higher framerates is a (more) fluid motion if you want that 'sharp' look.
Plus you can slow it down a little to get more cinematic. (sort of)

Good point Monty - plus you can use a higher shutter speed (1/120 over 1/100) and still create the 180 rule for perfect motion blur by recording at 60p rather than 50p. NTSC/PAL is pointless these days (unless you specially need 25 or 30 to match other footage from other devices of course).

I think the fact that we all watch movies of which 99% are filmed in 24 FPS tells us that serious film makers use this format when making films , we seen the Hobbit movie shot in 48fps was a total flop, and we have never seen any other movie shot in 48 FPS since, not much point in using 60fps unless you have motion in the shot,
I know they use 60fps a lot for vlogging on you tube these days , but I think it’s better used for that and maybe sports broadcast, it wouldn’t be considered very cinematic , I believe Hollywood standard is 24fps for purely cinematic reasons, so this would be my preferred option.

THX: High frame rates will become standard in movies
Few lines from article.

''These higher speeds are said to complement 3D, smoothing out the picture  and enhances the effect. But there has been criticism that it makes  movies look too real''
'' –  Warner is deeply involved with the standards bodies, which are  addressing the issues and preparing for high frame rates to become a  norm moving forward.''
''so it makes sense that filmmakers will want to use a better technology  that enables the viewer to have a more real-world and visually striking  experience''

Intestingly enough, Movie musical Oklahoma was shot at 30 FPS and 24 FPS back in 1955.  Followed by Around the World in 80 Days being shot at 30 FPS.

In my case the 50fps is needed for the grid frequency and my other cams that shoot 25 / 50 only .
I get nasty flickering at 30 / 60 with certain light sources.

Yes, that is true. Unless they want that 'sharp' look.
A lot of scenes from 'Saving private Ryan' were shot with that effect in mind (I think it is called the  45 degree shutter)

You can switch the frequency from 60Hz to 50Hz and engage anti flicker independent of the frame rate. I don't even get that flicker effect recording in my home on an evening in artificial light in NTSC.

I live in Germany - but I always use NTSC to get the 24fps that I prefer.

I do with some light sources.

With and without the flicker thing.
I also see it on LED screens from busses etc.

Yeah - there is a lot of info about it. I switched to NTSC to increase my frame rates ages ago and found that as long as I fly in natural light there is no difference at all to the footage quality except the ability to obviously increase the frame rates - especially 50 to 60p.

Yes, if it was my only camera (or all could make that switch) I would shoot more 60fps I guess.
But so far I try to shoot 50fps / 25fps only..
The one device that did not allow me to do so is the iPhone SE with the DJI Go app....
(for the osmo mobile)

Strange that the SE didn't allow.

I think this video gives a great understanding and the myths of frame rates.

That is very informative.

Well for me it cuts out a lot of the myths regarding frame rate.

Fly safe

Correct.   Frames per second has impact up to a point.  Too few frames per second, and movie goes from Cinematic (smooth) to Vintage film (jumpy).  Too many frames per second, and extra frames are wasted.   A few movie producers are saying 3D movies require at least 48 FPS (24 FPS per eye?).

I went the route up from 1080p 60fps and found that 30fps downscaled 4k footage just looks better to the eye. That's it. Now I'm stuck to 30fps @"4"k but I'm also considering moving down to 24fps for real 4K and work with that. I want a smooth cinematic look because it's about telling something. If I would capture a documentary I'd go for 1080p 60fps just to have the opportunity to show detail in movement patterns for example.

So for now we're stuck with 4k@24fps and the slightly cropped "its-still-4k-despite-its-not" at 30fps and all this has to do with sensor size and quality and of course processing power.
