Resume a paused series. Creating or changing a series is FREE. While active, the scheduler makes one video every scheduleIntervalDays (the first at its next run, within about 30 minutes) and charges each video like any video, at render — only when the balance covers it; a short balance skips that run, it never fails or overdraws. A series created or resumed through this connection counts each scheduled video against this key's daily agent spending cap (autoshort_get_limits); over the cap, that day's run is skipped.
