# I Plan the Ending Before I Generate the Video I’ve started planning AI videos from the last three seconds. It sounds backwards, but it solved a problem I kept running into: good openings with nowhere to go. I used to start with the first shot. A character walks into a café. The camera follows. Morning light comes through the window. Nice start. Then I’d keep adding things. They order coffee. Sit down. Open a laptop. Check their phone. Look outside. Pick up the cup. The camera moves again. Before long, a simple idea had six or seven actions fighting for attention. So I changed one small part of my process. Before writing the prompt, I ask: **What do I want to see in the final three seconds?** For the café idea, I might want to end with the character quietly working beside the window, coffee on the table and the morning rush happening outside. That gives me somewhere to go. Now I can work backwards. The ending is the character working by the window. The middle only needs to get them from the door to the table. The opening only needs to establish the café. Suddenly, I don’t need all those extra actions. I started thinking about this more while looking at longer-generation workflows around [Seedance 2.5](https://www.jxp.com/seedance/seedance-2-5). When a video has more room, my first instinct is to fill it. I'm learning to do the opposite. For that café scene, I’d probably keep only three beats: **0–6s:** Walk into the café. **6–18s:** Sit down and open the laptop as the morning light reaches the table. **18–25s:** Pull back slowly and end with the character working beside the window. That’s enough. The same trick works for other ideas too. For a travel clip, I decide what the final view should be before planning the walk toward it. For a simple product concept, I decide how I want the product to appear at the end before adding movement around it. It also gives me a quick way to reject weak ideas. If I can’t picture the last few seconds, I usually don’t write the full prompt yet. I used to think a longer AI video needed more things to happen. Now I think it just needs somewhere to go. So I write the ending first. Simple rule, but it has saved me from a lot of overloaded prompts.
