Spatial video is one of the genuinely convincing things about Apple Vision Pro, and it is also the format you have the least of. Everything shot before you owned the headset, everything sent to you by someone else, everything downloaded over the years, all of it is flat. Twineye exists to close that gap. It takes an ordinary video and converts it into a spatial video you can watch on Vision Pro, and it does the whole job on the device in your hands.
The technical claim worth paying attention to is that the depth model ships inside the app. There is no network step, no upload to somebody’s conversion server, and no data collection. That matters more than it might sound, because the obvious way to build this feature is to push your footage to a cloud GPU and mail back a result, which means handing over home video to a third party and waiting on someone else’s queue. Twineye keeps your files where they already are.
It is also free in the way the word is supposed to mean: no subscription, no in-app purchases, no ads. The app runs on iPhone, iPad, Mac and Vision Pro, so you can convert on whichever device happens to be nearby and watch the result in the headset. That flexibility is useful in practice, since the library you most want to convert usually lives on a phone or a Mac rather than on the headset itself.
There is a hardware requirement to be aware of before you start. Conversion depends on MV-HEVC encoding, which means an iPhone 15 Pro or an iPhone 16 or later, a Mac or iPad with Apple silicon, or Vision Pro itself. Older iPhones can run the app but will not be able to do the encoding work, so check what you are converting on before you plan a big session with the family archive.
For anyone who has watched a spatial clip in the headset and immediately wished the rest of their footage looked like that, this is the least demanding way to find out how well it translates. It costs nothing to try, it does not ask for an account, and the source files never leave your device while it works.
