AI WORLD HQ
If you've ever wanted to drop a building into a flaming wreck without buying a single firecracker, AI video tools are getting close. The new Seedance 2.5 guide walks through exactly how to make a believable blast — and the real lesson is bigger than the explosion itself.
The single-shot rule
The first thing the guide insists on: write the entire explosion as one shot. That's tempting to break. You'd think cutting between a wide view, a close-up, and a slow-motion ember would look better. But in AI video, every new shot is another generation, and the model loses the lighting, the angle, the camera energy between cuts.
One continuous prompt keeps everything consistent. The trade-off is that your prompt has to be very specific: camera angle, lighting direction, debris behavior, smoke color, duration. A prompt is just the instruction you type to the AI. Vague prompts give you vague blasts.
The 480p-then-1080p trick
This is the part worth stealing. AI video gets expensive fast — compute time is usually billed by the second, and higher resolutions cost more. The Seedance 2.5 workflow says: preview at 480p first. That's a low-resolution version — cheaper to render, faster to come back. You watch the preview, decide if the blast actually feels right, tweak your prompt, and run another cheap preview.
Only when the preview matches what you want do you generate the keeper — the final version you actually keep and use — at 1080p. Full HD. That's the version you deliver.
Why this matters: most people blow their budget on a single 1080p generation, find out the prompt was wrong, and either give up or pay again. The 480p-then-1080p pattern is the same idea as sketching before painting.
Shot types and keeping a product intact
The guide includes a shot-type table — a reference list of camera framings (think wide shots versus close-ups) and what each framing does to an explosion. Different shots need different prompt details. A wide shot lets the AI invent the background; a close-up needs you to specify every spark.
The last piece is reference tricks — feeding the AI reference images of the product you want visible during the blast. Without references, AI video tends to morph your product into something unrecognizable. With them, the bottle stays a bottle, even as the world explodes around it.
Wrap-up
Seedance 2.5's explosion guide is really a workflow lesson in disguise: one detailed prompt, two resolutions, a shot-type cheat sheet, and references to anchor the things you care about. Try the 480p-then-1080p pattern on your next AI video, on any subject. The savings are immediate, and your final clips will look better for it.
