图生视频 AI — 用 Seedance 让照片动起来

使用 AI 将静态图片转化为精彩视频。了解首帧、尾帧和多参考模式的精确视频生成。

Prepare source frames

Start with clear, high-quality source images that match your target composition.

When possible, keep lighting and lens perspective consistent across references.

Control movement deliberately

Use first-last frame mode for directional transitions and subject mode for identity retention.

Avoid forcing too many simultaneous motion constraints in one generation request.

Polish outputs efficiently

After selecting the best candidate, run focused refinements for pacing, camera smoothness, and scene continuity.

Export only after checking frame-to-frame artifacts at normal playback speed.
