Autosave and crash recovery

1 min read

Three separate mechanisms, covering three different disasters.

While recording

The recording is written to disk as it goes, in pieces, rather than held in memory and written at the end. If the machine dies mid take, the file on disk is a real video for everything up to that moment. It opens and it plays, and the Studio can restore the length and the index the recorder never got to write.

You lose the last moment, not the take.

While editing

The project is saved automatically about once a minute. The save is atomic: the new file is written completely and only then put in place, so a crash during a save cannot leave you with a half written project. There has always been either the old good file or the new good one.

Autosave pauses during an export and the footer tells you so.

After a crash

Next time the Studio starts, it notices the previous session did not close properly and offers to restore what it had. Take the offer. Then save under a name you chose, so you are not relying on a recovery file.

What none of this replaces

Saving on purpose, before you do something drastic, with a name you will recognise. Autosave protects you from the machine. It does not protect you from deciding, at midnight, to try something and then not being able to remember what the good version looked like.
