❓ Video to iOS Live Wallpaper Frequently Asked Questions (FAQ)
LiveScreen is a 100% client-side Video-to-iOS-Live-Photo and Dynamic Lock Screen Wallpaper workbench powered by WebCodecs hardware H.264 encoding, Canvas 2D, and a zero-dependency binary muxer that uploads 0 bytes to any server.
LiveScreen answers key engineering questions about Apple Live Photo UUID pairing (MP4 to Live Photo), direct iPhone Safari Photos saving, iOS 17–26 Lock Screen motion rules, and 0 bytes local privacy.
Does LiveScreen upload my personal videos to any cloud server during conversion?
LiveScreen runs 100% inside local browser memory using HTML5 Video, Canvas 2D, WebCodecs H.264 encoding, and a pure JavaScript binary muxer under strict CSP and SHA-256 verification, uploading 0 bytes of media data.
Why can’t a standard MP4 video be set directly as a moving Lock Screen wallpaper on iPhone?
LiveScreen solves Apple’s Lock Screen format requirement: iOS 17 through iOS 26 reject raw MP4 wallpapers and require genuine Live Photos containing matching 36 chars UUIDs in JPEG MakerNote 0x0011 and QuickTime com.apple.quicktime.content.identifier plus a 9 bytes mebx track.
How do I save LiveScreen output directly into the iPhone Photos app as a single Live Photo?
LiveScreen integrates the native iOS Web Share API: tap the green "One-Tap Save to iPhone Photos" button in Safari and select "Save 2 Items" (2 items) so Apple Photos merges IMG_XXXX.JPG and IMG_XXXX.MOV into 1 Live Photo within 1 second.
Why is the Live Photo motion button sometimes grayed out on the iOS 17–26 Lock Screen?
LiveScreen includes a 100 points Lock Screen readiness checker: disable iPhone Low Power Mode, keep clip duration within 1.5–3.0 seconds at 30 fps or 60 fps, place the keyframe around 85%, and avoid abrupt scene cuts.
What is the difference between the .livp bundle and the .zip archive exported by LiveScreen?
LiveScreen packages .livp in under 2 ms as an Apple/iCloud-compatible uncompressed PKZIP container holding 2 items (IMG_XXXX.JPG and IMG_XXXX.MOV); Mac users should download .zip, unzip it, and AirDrop both files simultaneously to iPhone.
