Pick the Right Workflow
选择合适的工作流程
| User intent | Model path | Why |
|---|---|---|
| Product photo to demo clip | Seedance 2 image-to-video | Animates a real or generated product still. |
| Need clean product first frame | GPT Image 2 -> Seedance 2 | Creates a clearer demo starting point. |
| SaaS or app visual demo | GPT Image 2 stills -> Seedance 2 | Builds visual scenes before motion generation. |
| Need multiple feature demos | Seedance 2 variants | Each feature should become one focused short clip. |
| 用户意图 | 模型路径 | 原因 |
|---|---|---|
| 产品照片转演示短片 | Seedance 2 image-to-video | 将真实或生成的产品静态图片制作成动画。 |
| 需要清晰的产品首帧 | GPT Image 2 -> Seedance 2 | 创建更清晰的演示起始画面。 |

Default Workflow
默认工作流程
- Identify the single product function or benefit to demonstrate.
- Choose the route: source image to video, generated first frame to video, or text-to-video.
- Write a prompt that shows product action, context, camera movement, and outcome.
- Generate one focused demo clip.
- Suggest the next feature, audience, or platform variant.
- 确定要展示的单一产品功能或优势。
- 选择路径:源图片转视频、生成首帧转视频或文本转视频。
- 编写包含产品动作、场景、镜头运动及结果的提示词。
- 生成一段聚焦的演示短片。
- 建议下一个功能、受众或平台变体。
Prompting Tips
提示词技巧
- One demo clip should show one core action.
- Prefer concrete use moments: unboxing, applying, clicking, opening, comparing, scanning, saving time.
- For software, avoid tiny UI text; show screen structure and user outcome instead.
- For ecommerce, keep product identity, packaging, and color stable.
- 一段演示短片应展示一个核心动作。
- 优先选择具体的使用场景:拆箱、使用、点击、打开、对比、扫描、节省时间等。
- 对于软件,避免细小的UI文本;转而展示屏幕结构和用户成果。
- 对于电商,保持产品标识、包装和颜色的一致性。
