First Frame Control/seedance-2-0

苍白女巫首尾帧过渡

首尾帧演示：苍白女巫从符文石墙前的特写过渡到符文发光的四分之三肖像，展示 8 秒跨构图插值。

Prompt

First-to-last frame demo with a fantasy character. Frame 1: a tight close-up of a pale sorceress with platinum braided hair, downcast gaze, lit by cold rim light against a stone wall etched with ancient runes. Frame 2: same character pulled back to a three-quarter portrait, gaze now meeting camera, runes glowing faintly. Seedance interpolates the 8s transition: subtle camera dolly back, gradual rune ignition, breath visible in cold air. Dark fantasy color palette — slate, ash, faint cyan emissive accents.

为什么有效

• Defining both frames with specific composition differences gives the model clear interpolation targets.
• The rune ignition provides a visual progression marker that makes the transition feel purposeful.
• The dark fantasy palette with minimal color accents keeps the output cohesive and cinematic.

可替换变量

• character design
• rune style
• lighting color
• transition pacing

实用建议

• If the face drifts between frames, reinforce "maintain exact facial features and platinum hair throughout".
• For a more dramatic transition, add environmental changes like rising mist or shifting shadows.
