VN Video Editor Not Working? Common Errors & Fixes

'Video generation failed' means VN couldn't finish writing your export. It's usually low storage, a missing source clip or settings too heavy for the phone: free several GB, switch export to Auto or 1080p and keep VN open until it finishes.

A VN export that freezes at 99% (or 0%, 10% or 50%) usually means the phone ran out of memory or overheated. Close background apps, let the phone cool, export at 1080p and, for long videos, export in parts.

VN shows 'Please reduce the export resolution' when the phone can't encode the chosen resolution. Pick 1080p or 720p in Manual export, or use Auto, and restart the app if it still appears.

VN crashes most often when adding filters or music, importing many clips, or opening big projects. Update the app, restart the phone, free storage and memory, and reduce layers or 4K clips in the project.

VN projects live only on your device: there's no cloud backup and signing in doesn't sync them. Check Drafts, try undo inside the project, and from now on export the project file as a backup.

When a VN project hangs on the processing screen (often at 50%) it's usually a heavy or broken clip or low memory. Restart the phone, free storage, update VN and check the project's source clips are still on the device.

VN preview lag grows with long timelines, many layers and 4K/HDR clips. Close background apps, free storage, clear the cache on Android and split big projects into parts.

VN audio drifting out of sync is mostly reported on long projects. Re-import the audio, realign it on the timeline, match export FPS to your source and export long videos in parts.

If music vanishes from a VN project or shows 'invalid audio', the file usually moved or is in an unsupported format. Keep the original file on the device and use MP3, WAV or AAC.

Black clips or 'missing' media in VN mean the app can't reach the original file, usually because it was moved, deleted or only stored in the cloud. Restore the file to the device or replace the clip before exporting.

When VN won't add clips (or freezes after you select them) it's usually photo permissions, cloud-only files or an app bug. Allow full photo access, download clips locally, restart and update VN.

If VN Pro doesn't show after you pay, make sure you're signed in to the same VN account and store account used for the purchase, then restart the app and contact VN support with the receipt.
