How do I make a longer, multi-scene video?
Storyboard automates the planning, Scene Builder gives you frame-level control, and Video Agent produces a finished narrated video from one topic.
No single model generates a long video — the longest clip on the platform is 30 seconds on Seedance 2.5. Anything longer is built from multiple clips, and there are four ways to do that depending on how much control you want.
Video Agent — the most automated
Give it a topic and it researches, scripts, generates the visuals, records the voiceover and renders a complete video. 30 to 180 seconds, in styles including explainer, animated story, UGC review, news, commercial and tutorial. Costs 80 credits for 30 seconds up to 280 for 180 seconds, with animation adding 50%.
Storyboard — automated planning, your execution
Describe a story and it generates the scene breakdown, the first frame for each scene and the video prompts. You then add video, voiceover, music and lipsync, and hand the finished timeline to the Video Editor. Best for story-driven content and pre-visualization.
Scene Builder — the most control
Write a prompt per scene, generate the still, edit it until it is right, then animate it. Because you can perfect every frame before spending video credits on it, this is the most economical way to get an exact result — and the most hands-on.
Commercial — product-focused
Upload a product, answer a few questions, and AI writes the concept, a full storyboard with per-scene image and video prompts, and the voiceover script, then generates the scene stills. Defaults to 8 scenes and exports straight to the Video Editor.
Whichever route you take, the Video Editor stitches the clips together and exports for free.
