visionOS is Apple's newest platform and requires the highest resolution of any App Store preview — full 4K. Getting the format right is critical: App Store Connect will silently reject uploads that don't meet the exact technical specifications.
3840 × 2160
Landscape only — 16:9 aspect ratio, 4K UHD
Orientation
Landscape
Apple Vision Pro is the only App Store device that requires 4K resolution. Portrait orientation is not supported for visionOS previews.
visionOS Simulator in Xcode
The most accessible option. Run your app in the visionOS Simulator and use Xcode's built-in screen capture. Make sure the Simulator window is set to the correct resolution before recording.
Reality Composer Pro
Ideal for spatial computing apps. Lets you preview and capture your 3D content in a controlled environment before generating your App Store preview.
Developer Strap (hardware capture)
Apple's Developer Strap enables direct screen capture from a physical Vision Pro headset. This gives the most authentic footage but requires the hardware accessory.
4K is demanding on encoding
3840×2160 produces very large files. Encoding must use H.264 High Profile at a high enough bitrate to avoid visible compression artifacts at 4K, while staying within App Store Connect's upload limits.
Simulator may not capture at native resolution
The visionOS Simulator's capture resolution depends on your Mac's display. If your display is smaller than 4K, the recording will need to be scaled up — which can introduce blurriness if not handled correctly.
Spatial video is not preview video
Apple Vision Pro supports spatial video (stereoscopic 3D), but App Store preview videos are standard 2D. Don't confuse the two formats — App Store Connect expects a flat 2D H.264 file.
Variable frame rate from screen capture
Screen recordings from the Simulator or Developer Strap are typically variable frame rate (VFR). App Store Connect requires constant 30 fps — VFR uploads will be rejected.
