About this skill

generate-video

The base video skill. Use it standalone for one-off clips, or as a building block under more specific skills (/clone-ad, /wide-cam-podcast, /generate-talking-head). The skill's job is to turn a rough idea into a finished MP4 — refining the prompt and picking the right model along the way.

Providers

  • Wavespeed — pull https://wavespeed.ai/docs for the current API surface; model-specific endpoints under https://wavespeed.ai/docs/docs-api/... (e.g. bytedance/bytedance-seedance-2.0-image-to-video, kwai/kling-v3-pro, openai/sora-2)

Pick the model

Model Best for Trade-off
Seedance 2.0 UGC ads, talking-heads, multi-cut social videos. Native audio generated from prompt text. Up to ~15s. Prompt must use explicit CUT. SHOT N: blocks — narrative beats produce flat single-take output.
Kling 3.0 Character continuity, lip-sync from reference image, longer cinematic clips. No native audio — pair with /clone-voice + /swap-voice if dialogue is needed.
Sora 2 Complex multi-element scenes, hyperrealistic environments, "wow factor" hero shots. Slowest and most expensive. Reach for it when Seedance and Kling can't deliver the idea.

Default: Seedance 2.0 for social, Kling 3.0 for character-driven content, Sora 2 only when the idea forces it.

Steps

  1. Capture the idea. Ask the user for: subject/concept, what should happen on screen, desired length, target platform (TikTok / IG Reels / YouTube → aspect ratio), and whether they have a reference image to use as a starting frame.
  2. Refine the prompt. Rewrite the idea into a model-appropriate structured prompt:
    • Seedance 2.0 → shot list with CUT. SHOT N: blocks naming framing, angle, movement, location, action, and dialogue per shot. Aim for 4–5 cuts per 10s for UGC energy.
    • Kling 3.0 → character description + scene + camera move + duration. Reference image carries identity.
    • Sora 2 → environment + subject + action + style + camera. Less rigid structure than Seedance; closer to a paragraph. Read the refined prompt back to the user and iterate before any provider call.
  3. Pick the model from the table above.
  4. Set the params. Aspect ratio (9:16 TikTok/IG, 1:1 Meta static, 16:9 YouTube), resolution (480p for authentic-looking social, 720p+ for higher fidelity), duration, native audio on/off (Seedance only).
  5. Generate. Call Wavespeed's image-to-video endpoint if a reference image was provided, otherwise text-to-video. Poll the job until done, download the MP4 to CWD/generate-video-<timestamp>/clip.mp4.
  6. Show the user the result and offer to regenerate with prompt or model adjustments. Save the final prompt alongside the MP4.

Input

  • Idea (subject, action, scene)
  • (optional) Reference image for image-to-video
  • Target platform / aspect ratio
  • Duration

Output

  • MP4 at CWD/generate-video-<timestamp>/clip.mp4
  • Wavespeed-hosted URL (valid ~7 days) printed for quick preview
  • The final prompt saved alongside the MP4 for iteration

Common failure modes

  • Flat single-take Seedance output — prompt described narrative beats, not shots. Rewrite with explicit CUT. markers.
  • Kling identity drift — reference image angle was too dynamic. Use a clean 3/4 profile starting frame.
  • Sora burn rate — defaulted to Sora when Seedance would have worked. Always justify Sora before reaching for it.
