**Music.** Choose a mood (calm, uplifting, dark, energetic, dreamy or corporate) and a length of 10, 15, 30 or 60 seconds. A loop folds its tail into its start so it repeats without a seam. Cost: 1 credit per 10 seconds, times the takes.

**Effects.** Describe it and choose 0.5 to 15 seconds, with a loop if you like. The Preview recognises words such as rain, wind, whoosh, beep, boom, click, laser and chime. Cost: 1 credit, times the takes.
