LumaFusion Not Working? Common Errors & Fixes

LumaFusion export errors are usually caused by low storage, problem media or speed-adjusted clips. Restart, free space, run Optimize and Consolidate, and if the project has speed changes turn off Use Audio Pre-rendering in Help and Settings.

This export error means LumaFusion can't decode one of your clips during export. Switching the export codec (for example H.264 to H.265) usually gets past it; otherwise Optimize and Consolidate or transcode the problem clip.

LumaFusion shows missing media when it can't reach a clip's source, usually an external drive, cloud service or cached file that was cleaned up. Reconnect the source or re-import the file, then Optimize and Consolidate so the media is stored with the project.

If you didn't delete the app, missing LumaFusion projects are usually hidden by a nearly full device: free storage, restart, then import a project backup. If you deleted and reinstalled the app, projects can only come back from a device backup.

Most LumaFusion crashes are fixed by updating the app (several crash fixes shipped in 2026), restarting the device, freeing storage and removing heavy third-party audio plug-ins. Don't delete the app: that erases your projects.

Choppy LumaFusion playback usually comes from footage iOS struggles to decode (4K, GoPro, DJI) or from editing off an external drive. Optimize and Consolidate the project, transcode problem clips, and keep media on internal storage.

A known LumaFusion bug drops audio from exports when the Sound Isolation preset's Sound To Isolate setting is High Quality Voice. Change it to Voice and export again.

LumaFusion on iOS can't import WMV, AVI, MKV, FLV, AV1, DivX, VP9, ProRes RAW or interlaced video. Convert the file to H.264 MP4 with HandBrake using Luma Touch's recommended settings.

LumaFusion copies imported media into its own storage, so it grows fast. Back up old projects as Project Packages, delete unused imported clips, clean cached media in Help and Settings, then restart so iOS releases 'System Data'.

On macOS 27, LumaFusion can crash when minimized or when you switch away from it in full screen. Luma Touch is working with Apple; until then hide it with Cmd+H and keep it windowed.

'No purchases were restored' means either the feature is already unlocked or you never bought it: add-ons like Multicam Studio aren't part of the base app. The old 'Cannot verify LumaFusion purchase' export error is fixed by updating the app and iOS.

Luma Touch removed Google Drive as a built-in source in LumaFusion. On iPad and iPhone, install the Google Drive app and import/export through Files or the share sheet instead.

LumaFusion for Android/ChromeOS needs at least 3 GB of RAM and Android 10 or newer. If your Chromebook runs Android 9 or lower, it won't install unless a newer ChromeOS channel brings Android 10+.

iOS projects using Multicam Studio, Adjustment Clips, more than 6 video/audio tracks, AUv3 plug-ins or certain transitions can't be opened in LumaFusion for Android/ChromeOS. Remove those features on iPad before moving the project.
