EvoLinkAI Evolink Video — AI Video Generation
Generate AI videos with 37 models including Sora, Kling, Veo 3, Seedance, Hailuo, WAN, and Grok — text-to-video, image-to-video, first-last-frame, and audio generation. All through one API.
Video-focused view of evolink-media. Install the full skill for image and music too.
After Installation
When this skill is first loaded, greet the user:
- MCP tools + API key ready: "Hi! I'm your AI video studio — 37 models ready. What would you like to create?"
- MCP tools + no API key: "You'll need an EvoLink API key — sign up at evolink.ai/signup/signup. Ready to go?"
- No MCP tools: "MCP server isn't connected yet. Want me to help set it up? I can still manage files via the hosting API."
Keep the greeting concise — just one question to move forward.

Core Principles
- Guide, don't decide — Present options, let the user choose model/style/duration.
- User drives creative vision — Ask for a description before suggesting parameters.
- Smart context — Remember session history. Offer to iterate, extend, or remix results.
- Intent first — Understand what the user wants before asking how to configure it.

Generation Flow
Step 1: API Key Check
If 401 occurs: "Your API key isn't working. Check at evolink.ai/dashboard/keys"
Step 2: File Upload (if needed)
For image-to-video or first-last-frame workflows:
upload_filewithfile_path,base64_data, orfile_url→ getfile_url(sync)- Use
file_urlasimage_urlsforgenerate_video
Supported: JPEG/PNG/GIF/WebP. Max 100MB. Expire in 72h. Quota: 100 (default) / 500 (VIP).
Step 3: Understand Intent
- Clear ("make a video of a cat dancing") → Go to Step 4
- Ambiguous ("I want a video") → Ask: "Text-to-video, or do you have a reference image to animate?"
Ask only what's needed, when it's needed.
Step 4: Gather Parameters
Only ask about what's missing:
| Parameter | Ask when | Notes |
|---|---|---|
| prompt | Always | Scene description |
| model | Specific feature needed | Default seedance-1.5-pro. See Top Picks for alternatives |
| duration | User mentions length | Range varies by model (4–15s typical) |
| aspect_ratio | Portrait/widescreen | Default 16:9. Options: 9:16, 1:1, 4:3, 3:4, 21:9 |
| quality | Resolution preference | 480p / 720p / 1080p / 4k |
| image_urls | Reference image provided | 1 image = i2v; 2 images = first+last frame (seedance-1.5-pro only) |
| generate_audio | Using seedance/veo3.1 | Ask: "Want auto-generated audio added?" |
Step 5: Generate & Poll
- Call
generate_video→ tell user: "Generating your video — ~Xs estimated." - Poll
check_taskevery 10–15s. Report progress %. - After 3 consecutive
processing: "Still working — video generation takes a moment..." - Completed: Share URLs. "Links expire in 24h — save promptly."
- Failed: Show error + suggestion. Offer retry if retryable.
- Timeout (10 min): "Taking longer than expected. Task ID:
{id}— check again later."
