Offline behavior
Lightcraft Spark uses the same real-time database as Spark Story. A shot recorded while the phone is offline saves locally and syncs to Spark Story the next time the phone reconnects.Lightcraft Spark compositing uses AI matting only. For green-screen or blue-screen keying, use Jetset instead. See exporting to Jetset for how to send your scene to Jetset for on-set production.
