A clear shot plan starts here.

Three connected story beats and prompts adapted for Seedance 2.5 and MiniMax H3 will appear here.

01

Describe the scene

Write what should happen on screen. A rough idea is enough.

02

Choose your frame

Select the aspect ratio and visual mood. The same idea feeds both prompts.

03

Adapt for each model

Get continuity anchors, three story beats, a connected Seedance prompt and a compact H3 prompt.

A real Callirra run

Why one clear camera move matters

Our MiniMax H3 “Lantern on a Canal” example is a compact, continuous scene: one paper lantern moves down a wet canal while the camera holds low, then pushes in slowly. Its prompt fixes the light source, direction of travel and background. The measured output is 5.167 seconds at 1344×768 and 24 fps. This is an existing run, not a promised result from this text tool.

The builder gives H3 one focused action and camera move, while the Seedance version connects several beats. Inspect the actual clip and prompt before refining your scene.

Original prompt · Lantern on a Canal

This is the prompt used for the measured clip above. Results can vary between runs.

integrated_multimodal_description: [Shot 1] Live-action, cinematic, shallow depth of field. A single paper lantern drifts down a narrow canal at night in a southern Chinese water town, seen from a low camera just above the waterline. The lantern's warm orange glow is the only light source near the camera, and it throws a soft moving pool of colour across the wet stone walls on either side. The camera holds a static shot, letting the lantern travel from the upper third of the frame down toward the lower right, then the camera pushes in with small amplitude at slow speed as the lantern passes and its reflection breaks apart on the ripples and reforms. Background: whitewashed houses with dark tiled roofs, a few windows still lit. Light rain has just stopped; the air is thick and the far end of the canal dissolves into mist.

overall_soundscape: Quiet night in a water town. Water laps gently against stone, the rain that has just stopped drips from the eaves into the canal at irregular intervals, and the lantern's paper and thin bamboo frame creak faintly as it turns. A distant dog barks once, and a single bicycle bell rings far away.

non_diegetic_music: A sparse solo guzheng melody at a slow tempo, played with long pauses between phrases, the strings allowed to ring and decay. No percussion.

What makes a video prompt useful?

A model needs visible actions, a setting, subject details and a camera path. A multi-beat story also needs continuity: repeated character traits, wardrobe, light direction and location. This builder makes those anchors explicit so you can edit them before generating.

Why two prompts? A connected sequence and one compact continuous shot need different pacing. Use the Seedance version as a sequence and the H3 version as a focused short shot; compare actual results rather than assuming either model follows every instruction.

The output is a draft, not a promise that a specific model will follow every beat or accept every request. Always review the prompt and respect the model’s rules and the rights of people shown.
