I've described what kind of video this camera is intended to capture: https://blog.mikeswanson.com/apples-mysterious-fisheye-proje...

I just want to say that your analysis is great. I reference it whenever the discussion comes up about the technicalities of Apples solution.

Thank you! I really appreciate the feedback.

I guess the next step here is a video encoder that is natively recording spherical videos ?

Any projection is bound to separate areas which could be compressed more efficiently together.

A native stereoscopic spherical video encoder could improve compression even more, since side by side views are quite similar in general.

Now that's an interesting problem to solve ! (and a very hard one probably)

Existing video formats already support this for interlacing, although you could also let inter-prediction refer to earlier parts of the same frame and get most of the benefit.

It is developed in the mpeg standard already, there is a whole group of people for that from some years ;)

Hey! Nice writeup, Just something is missing, some MPEG formats can encode this kind of video in OMAF specification.

Edit: I'll certainly read the rest of the articles!

[mdswanson]

Thanks! Indeed, there are other formats (like OMAF) that describe some of this. In fact, I helped to author one a long while back called OPF.

Did WWDC end up filling in any additional blanks from your article?

Thanks!

[mdswanson]

Unfortunately not. I hope we learn more before WWDC25!
