The cast is generous but capped, thirty images, ten clips, ten sounds, so a bigger cast needs trimming first. ## How to use it 1. Use the card's **References** area. Your cast of pictures, clips and sounds. Name each one in the sentence that directs the shot. 2. Write what you want in **Prompt**. 3. Set **Draft first**, **Duration**, **Resolution**, **Ratio** on the card. 4. Pick a mode on the card: **Generate**, **Edit clip**. 5.
