iPhone 8: How exactly does it achieve extreme framerates? 1080p240fps+4K60.

[TechLord]

Hello.
(Yes, my Quora account is dead again. Their moderators, just like coal686 on XDA forums, are subjective thinkers.)
As an Android phone user, there is one thing I was always jealous about:
The iPhone's superior camcorder framerate.

It is not something that Apple users would care about, according to Twitter user @AppleSucks7.

The iPhone 5s and Note 3 achieved 720p at 120fps in 2013.
Note 3 also delivered 1080p at 60fps and 2160p at 30fps.
But the 5s encoded the 120fps footage in real-time with sound, so that it can be used in more versatile ways (watch as normal video, or slow down twice to have 60fps to spare; video editing) instead of for amateurs.

I consider anything starting with 240fps as suitable for slow motion, because slowing down four times leaves smooth 60fps to spare.

However, the iPhone 6 achieved 720p at 240fps in late 2014.
The S7 did the same in early 2016, but the video encoder (still on Note 8!) does skip some frames, increasingly with video length, so that after three minutes of capturing, the effective video framerate is not even 60fps.

OnePlus 5 is still stuck at 720p at 120fps, which is not understandable to me. It has three times as many system resources as the iPhone 6.

In early 2015, a MT6795 chipset from MediaTek was proposed to achieve glorious 1080p at 480fps without fixed time limitation! This equals 2160p at 120fps or 4320p at 30fps! 99532800 pixels per second.

Now, iPhone users, who probably would not care (proven by tests by Jimmy Kinmel), have access to 2160p at 60fps and 1080p at 240fps!

I wonder, how exactly Android is still not capable of even 1080p at 120fps mostly! (only a few phones such as the Google Pixel series, that lack optical image stabilisation anyways.)

The iPhone camera application has an inferior UI (but with superior AE/AF locking/compensation controls, which I may explain later), but is working smooth. The Note 8 camera application (unlike the one from Note 2, 3, 4) does even skip frames and add shutter delay, because it depends on screen rotation, which is really irrelevant for me when using the camera interface. Probably, that was the idea of the minimalism monster Hyun Yeul Lee.

How exactly does Apple achieve these superior framerate?
And why don't competitors nearly reach these framerates?
Xperia xZ premium does not count, because of the short time limit.
The iPhone 8 achieves better framerates than the GH5, HC-X1000e and even the most recent Sony RX10 and RX100 series!
How exactly is that possible?


I hope that you consider providing an explanation.
I would appreciate any help for solving this mystery

Prove it... i seriously doubt on declared specs or capabilities - inherit jitter is unavoidable with such SoC's...

People who think Apple is the leader in smartphone technology are either just fanbois or don't know how to do their own research. There is something out there called Google and while I am too lazy to check, IIRC Apple uses Sony sensors in their phones which brings me to my final point. Sony is the current leader in frame rate with the Xperia XZ Premium capable of 960 fps. And, yes, it is an Android phone.

I did not claim Apple to be a leader.
But I am asking: How does it achieve 1080p@240fps, while even Galaxy Note 8 is stuck at 1080p@60fps and OnePlus 5T at 720p@120fps?

The Galaxy Note 3 from 2013 already had 2160p30fps(=248832000px/s);1080p60fps(=124416000);720p120fps(=110592000).

How can the OnePlus 5T still have the same resolution and framerate (at maybe just a bit of higher quality)?

And the Galaxy Note 8 still has the dead-ugly Galaxy S7 lag-bug.

It doesn't achieve those numbers in reality, it just claims them. Or, if it achieves one element of them, something else is getting fudged elsewhere. You cannot cheat physics.

As Cornucopia already answered.... they cheat, very probably.

Just as an example — by using a timescale = 1 millisecond && always shooting with variable frame rate, then magically all your videos are recorded /encoded at 1000 FPS

In the grand scheme of things, a phone is a complete POS for video.
The sensors are toys.

I have a decade-old pro dSLR that will outperform the newest of phones in terms of quality, both video and photo.

If you want to shoot video, then buy a camera. Not a phone.
