What do you get back from sync-3 Lipsync, and how long does a run take?
Every run returns one video. Audio carries over from the source rather than being regenerated. Speech is re-synced to the lips. Runs are queued and processed in the background, so you can close the tab — the finished file turns up in your library. We do not quote a fixed wall-clock time: it moves with the length of the run and with how busy the queue is.
