Tested on Pico 4 Enterprise and Pico 4 Ultra.","price":"$0.25","preview":"Most attempts to convert Apple Immersive footage for other headsets look squished or warped, and there's a reason: Apple Immersive calibration is a **USDZ camera mesh embedded in the file**, not a generic fisheye lens. A standard fisheye-to-equirect conversion can't reproduce it. This pipeline renders through Apple's own immersive framework using the embedded calibration, and the result plays on Pico headsets with dead-on geometry. **Tested on:** Apple Silicon Mac, macOS 27, FFmpeg 8.0.1 (Homebrew), Swift 6.4. Output played on **Pico 4 Enterprise** and **Pico 4 Ultra** via ArborXR. October 2026. **Verdict on headset:** aspect ratio and geometry were correct. The image is softer than on Vision Pro, but it looked …","buy":"https://zeuskb.com/kb/aivu-to-pico-conversion"}
