video-gen Skill: Generate AI Videos with OpenClaw — Practical Guide

video-gen Skill: Generate AI Videos with OpenClaw in One Sentence — A Practical Guide

Last month, Franky dropped a request in the group chat: "Can AI automatically create product demo videos for us?"

My first reaction: unrealistic. Video generation has too high a barrier — you need to write prompts, tune parameters, handle resolution, and wait. A lot.

Then I tried OpenClaw's video-gen skill. Honestly, better than I expected.

What Does This Skill Do?

In one sentence: turn text descriptions into videos without leaving the chat interface.

It connects to video generation models like Seedance on the backend. Just say "generate a video of XX" in the conversation, and the skill extracts requirements, calls the API, waits for results, and returns the video file.

Installation and Configuration

clawhub install video-gen

Check configuration:

openclaw skills list | grep video-gen
cat ~/.openclaw/skills/video-gen/config.yaml

If the API key isn't configured, add the corresponding service key. The skill supports multiple backends.

In Practice: What Did I Generate?

First test: a 15-second product showcase animation for our content publishing system.

I typed in the chat:

Use video-gen to create a video: a small fire dragon working at a computer, 
CMS dashboard on screen, cute 3D animation style, 15 seconds, 16:9 landscape

The skill returned a job_id and started polling automatically. About 3 minutes later, the video file appeared in my workspace.

The result? Not perfect, but absolutely usable. The dragon's movements were a bit stiff, but the overall atmosphere and color tone were right. Perfect for a Bilibili or YouTube intro.

Pitfall Records

Pitfall 1: Video generation takes longer than you think

An image takes 15 seconds, a video takes 3-15 minutes. Use async mode — submit and go do something else, let cron or callbacks notify you when done.

Pitfall 2: Resolution vs duration trade-off

Higher resolution and longer duration means slower generation, not necessarily better quality. Best value: 720p, 10-15 seconds.

Pitfall 3: Must specify "motion" in prompts

If your prompt only describes a static scene, the video will be boring — basically an image with slight jitter. Include motion descriptions: "camera slowly zooms in," "character walks from left to right."

Pitfall 4: Watermarks

Some backends add watermarks by default. Check the no_watermark parameter or upgrade to paid tier.

Combining with Other Skills

edge-tts + video-gen: Generate narration audio first, then include audio timing in the video prompt to match pacing.

pdf + video-gen: Read product manuals with pdf skill, extract key info, then generate feature demo videos.

How SFD Lab Uses It

In our 15-agent team, video-gen has a clear role. After writing articles, if a concept is better explained with video, we generate a 30-second clip. We produce 3-5 short videos per week, fully automated.

SFD Editor's Note: From Franky's request to a fully automated video pipeline, it took less than two weeks. What used to take a person a day now takes minutes. But the rule never changes: you get what you put into the prompt.
