- somethingsome 2y agoHey! 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 2y agoThanks! 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.
- dagmx 2y agoI just want to say that your analysis is great. I reference it whenever the discussion comes up about the technicalities of Apples solution.
- mdswanson 2y agoThank you! I really appreciate the feedback.
- 4gotunameagain 2y agoI 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)
- somethingsome 2y agoIt is developed in the mpeg standard already, there is a whole group of people for that from some years ;)
- astrange 2y ago> A native stereoscopic spherical video encoder could improve compression even more, since side by side views are quite similar in general. 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.

- mdswanson 2y agoUnfortunately not. I hope we learn more before WWDC25!
