Mavic 3 Pro 60 FPS v 24

[trisen1981]

Hello - I was wondering if there is image quality difference between 24 FPS and 60 FPS on Mavic 3 Pro.

Technically in 24 FPS less data should be written on the card - and potentially less compression -> increased BitRate per second

But is it actually happens or image quality - mostly noise is same in both 24 and 60 FPS at 4k

Has anyone done some comparison?

The bitrate determines the amount of data per frame in the video. If you intend to extract still frames from your video, you'll want 24 fps, not 60 fps. 60fps is intended for slow motion. However, you'll actually have the best results with 30 fps because it most closely matches a multiple of the Hertz refresh rate on mobile devices used for consumption of video.

60fps also loses a stop of light in low light, as the slowest shutter speed becomes 1/60 rather than 1/30. Don't use ND filters for a cinematic effect if you intend to extract usable still frames, as the desired motion blur ruins still frames.

Glad you explained this. In the past when I knew I might want to extract still frames I assumed that 60 FPS was the way to go as I’d have a 1/120 shutter speed for sharper stills. Not realizing there would be any drop in quality on the still image.

Or am I reading that wrong and you’re just referring to not being able to go slower than 60th of the second if light is low?

I am not looking to extract still frames but rather want better quality (less noise) for the video.

If you want to extract stills - just not used ND filters at all and go for faster shutter speed - all will be crystal clear and sharp without any motion blur at all

Tody I recorded some test with 60 FPS and 30 FPS

30 FPs bitrate 112565 kbps
60 FPS 135494 kbps

So double the frame rate but the bitrate is not doubled - that makes me thing that 30 FPS supposed to be a bit better quality that 60 FPS - however visually I hardly see much difference
