Projects
Last updated
A project is the complete document: assets and compositions, together with
their settings. It is saved as a .lum file.

Footage and media are never embedded. The project file stores references to files, and Lumit never modifies those files.
Save and open
Section titled “Save and open”- File ▸ Save saves the project.
- File ▸ Save as… saves to a new path. If already saved, it creates a new copy at the location.
- File ▸ Open project… opens a
.lumfile, Open recent lists the last few.
Autosave
Section titled “Autosave”Lumit keeps rotating autosave copies in an autosaves/ folder beside the project. They
are written on an interval while the project has unsaved changes, and again before risky
operations such as starting an export. The interval and how many copies are kept are both
under Settings, on the Autosave page; turning the interval to zero switches the timer off.
A project that has not changed since its last save or autosave writes nothing.
Crash recovery
Section titled “Crash recovery”Between saves, Lumit also records every edit. If Lumit crashes, the next launch offers a dialogue with three choices:
| Choice | Recovers |
|---|---|
| Replay the edit journal | Everything up to the moment things stopped. |
| Open the newest autosave | The project as it was at the last autosave. |
| Open the saved file as it is | The last time you manually saved. |
File ▸ Recover… opens the same dialogue at any time. This is only available if a crash has occurred.
