Treat Your References Like Function Arguments: A Developer's Mental Model for Video-to-Video AI

说明与用途

在视频到视频生成中，源视频成为合同，引用是参数，提示是连接。采用类似函数的方法可减少重试并提高可预测性。

问题

Video‑to‑video generation feels unstructured because the source video is treated as a suggestion rather than a specification, leading to noisy prompts and many retries.

结果

Using the function‑call mental model reduces prompt noise, improves consistency, and lowers the number of costly retries.

工作流

• 1. Choose a source video that is a single continuous shot and contains the desired motion and framing.
• 2. Upload reference images, each dedicated to a single attribute (e.g., face, outfit).
• 3. Use positional reference syntax (e.g., @Image1, @Image2) in the prompt to map references to the source.
• 4. Select mode: "motion" to transfer movement or "swap" to replace a specific element.
• 5. Run a low‑resolution draft (480p) to validate identity, framing, and reference placement.
• 6. If satisfied, re‑render at higher resolution (720p/1080p).
• 7. Log each run in a JSON file with source, refs, prompt, mode, resolution, and notes for reproducibility.

证据

The key insight: the source video is not a suggestion, it is the bulk of your specification.

来源

Keep the prompt about mapping, not motion. Don’t redescribe the dance.

来源

Draft at low resolution. Run 480p to check identity, framing and that the right reference landed in the right place.

If you want to poke at this without wiring up any infrastructure, I've been experimenting with Genjutsu, a browser-based video-to-video generator
