Sessions Preferences
Pro
Sessions is an Orbit Pro feature.
A handful of settings governing how Orbit's session bundles are auto-saved and how the temporary "untitled" bundles created by preview-mode work are managed on disk. For the feature itself — what's in a session, how to create one, what's persisted — see Sessions.
Auto-save
Auto-Save Sessions — when on, Orbit saves the session bundle 2.5 seconds after every meaningful edit. Default is on.
The auto-save covers everything that lives in the session: video edit list, markers, loop regions, channel routing, solo and mute state, monitoring settings, and the playlist. It does not cover audio source files (those are referenced, not copied into the bundle), nor preferences (those live in AppSettings, not the session).
Untitled sessions — the ones Orbit creates implicitly when you load a file in preview mode and start tweaking — auto-save regardless of this toggle. That's deliberate: their entire reason to exist is crash recovery, so disabling auto-save for them would defeat the point. The toggle only governs explicitly-named sessions.
TIP
Leave Auto-Save on. The 2.5-second debounce means it doesn't interrupt your work, the saves are atomic so a crash mid-save can't corrupt the bundle, and it's the only thing protecting against losing edits if Orbit (or macOS) drops out unexpectedly.
Temporary bundles
Untitled sessions live in Orbit's temporary directory. They accumulate over time — every preview-mode load that lasts more than a few seconds leaves one behind, and Orbit doesn't delete them automatically because that's the wrong call when you might want to recover one after a crash.
Clear All — deletes every untitled temporary bundle from disk. A confirmation alert is shown before deletion since this is irreversible. Disabled when there are no temporary bundles to clear.
A small counter next to the button shows the current count ("3 temporary sessions on disk"), refreshed when the panel opens and after a clear. Useful for spotting when the count has crept high enough to be worth a clean-up — typically when you've been working on a lot of one-off files.
