With the new function Hyperlapse DJI has created a very good extension for the Pocket.
However, I can not understand why the restriction was made to 1080p.

Or am I alone, who wishes 4k.

Udo, you are not alone, I think everyone wants it, but the limitation is on the OP hardware.

I simply would like true hyperlapse, not speeded up video. I can do that in post!

This is the bit I don't understand. What extra processing does this function involve that prohibits it from recording in 4K? I mean you can record 60fps in 4K but not 6fps?

CemAygun, if the OP only serve 4K 6fs, of course it can possibly work, but there are many settings at the OP, the firmware size is limited, processor power is limited, hardware also limited too.

In theory, everything is possible.  Think if it is not an electronic device, and back to the old film days, you can use whatever size of the film and crank it at any frame rate. but that machine will be complicate and big, or has many parts with very high flexibility. Of course people will say, computer can do a lot faster and easier, yes, it it correct, then we need a faster and more powerful processor, a bigger battery, and a faster storage media, which hardly can be possible on an OP at this price tag and size.

And, if we compare the Osmo Pocket with Osmo Action, same sensor but OA can do more, because it consumes less processing power on the gimbal and tracking.

I think the 1080p limitation has something to do with electric stablization, somehow like what OA uses, in this way you have to crop the images which means full 4k resolution is impossible.

With GoPro Hero 7 Black it is possible in 4K.

Record video in 4K, then speed it up in post.  

Voilà - Pocket style 4K hyperlapse

Well, osmo action also has a resolution limit for hyperlapse (higher than OP but understandable for the reasons stated above) so there must be something going on,  it cannot be just frame skipping. Frame skipping would not require any power at all. That is why older, under powered cameras could do 4k at lower frame rates (generally 15 fps) at first.

For me, the hard part is trying to understand what possible factors there could be that would make it more of a challenge for software/hardware to shoot 4K at maybe 10 FPS than doing it at 4K 60 FPS like it's already doing. I would have naturally thought that the 4K60 would obviously be harder on software/hardware.

What is so special about a hyperlapse that it would be a harder task to pull off? (P.S. Serious question, as I really find it hard to understand how any mode, especially one that's shooting at such few frames per second, could be more demanding that shooting in 4K60 with the gimbal doing its magic.)

Well there are a number of advanced algorithms which can be utilized that would require serious power  (to get smoother, more fluid hyperlapse) but the problem is I personally cannot tell if there is anything other than frame skipping going on.

The only way to be sure is record 2 samples side by side, one as regular 1080p and one as hyperlapse, then speed up the regular video to match the other's speed and compare the results.

Unfortunately I own only one OP...

From testing the Hyperlapse, what I miss the most is the high bitrate (100mbps).
Hyperlapse is fast moving image and compression with 30~35mbps is just not enough to maintain the crisp phicture.

If not 4K video, I would prefer to save original image to jpeg like timelapse does.
(Or 100mbps 1080p would do fine.)

There are no "originals".

But the GoPro doesn't have a gimbal to process at the same time - surely this must make a difference?

CemAygun I have done it, but not in 1080p, in 4k 30fps

Which is better?

Yes here you can see the difference. Booth in 4k Project.

Wow such a nice comparison.
In image quality wise, no doubt 4K video is much better.
But Hyperlapse noticeably maintains the camera to the center and has much smoother rotation.
I guess Hyperlapse mode has some better gimbal algorithm.

I'm interested that nobody seems concerned about  output frame rate - is 30fps going to give good results on, say, a 50fps timeline?

Udo13, first of all thanks a lot for the effort, very nice comparison... Apart from better centering (unless that is a coincidence of course) I also cannot see any other difference. Does not look like the hyperlapse mode involves some sort of different, CPU heavy processing.

I do not recognize the difference either. Normally, the picture would have to be smaller, cropped.Maybe we will get an answer from DJI.

In a 50fps Project the video is 20% faster. Is it a Problem for you?

Actually I hadn't thought of it like that.  Very good point.  I guess it's a matter of thinking through the speed settings for hyperlapse in relation to the timeline setting you are going to use.  Still, technically I would have thought it wouldn't be hard for them to provide settings for output fps, found  by swiping from the Hyperlapse option.
