How can we
help you?

Nully supports most common video formats including MP4, MOV, AVI, MKV, and WebM. You can also convert between formats using the Quick Action Convert tool on the home screen.

Yes, projects have a combined file size limit of 500 MB for imported video files. This ensures smooth editing performance on mobile devices. You can split larger projects into smaller parts.

All projects are saved locally on your device. Nully never uploads your video files or project data to any external server. You can manage or delete projects from the home screen.

Yes! Nully includes a full-featured text overlay editor. You can customize fonts, colors, size, position, animations (fade in, scale, bounce), and more. Text overlays are rendered as part of your final export.

Nully collects only anonymous usage analytics (via Firebase) and crash reports to help us improve the app. We never access your videos, photos, or personal files beyond what's needed for editing. See our Privacy Policy for full details.

Try these steps: (1) Make sure you have enough free storage on your device. (2) Close other apps to free up memory. (3) Try exporting at a lower resolution. (4) Restart the app and try again. If the issue persists, contact us with your device model and OS version.

In the editor timeline, tap the junction between two clips. A transition picker will appear where you can choose from available transitions. Each transition can be customized and is fully reversible with undo/redo.
