The Problem

Creating short videos for product marketing, social media, or customer demos usually means: hire a video editor, wait days, pay thousands. Or open a desktop app, learn the timeline, export, re-export when something's wrong.

What if your AI agent could do it? Text in, MP4 out. Server-side. No desktop app, no manual editing, no waiting for renders.

Introducing AI Video Studio

AI Video Studio is an open-source OpenClaw skill that chains two powerful tools:

Seedance 2.0 (ByteDance Doubao) — AI video generation from text/image prompts
FFmpeg — Server-side rendering: clip concatenation, subtitle burn-in, BGM mixing
CapCut Mate (optional) — Jianying draft creation for advanced timeline editing

How It Works

Write a storyboard in JSON, run one command, get an MP4:

{
  "title": "Product Ad",
  "ratio": "16:9",
  "shots": [
    {"prompt": "Smartphone floating in space", "duration": 5, "caption": "Next-Gen Design"},
    {"prompt": "Hands holding phone with holographic UI", "duration": 5, "caption": "Intelligence at Your Fingertips"}
  ]
}

python3 studio.py pipeline storyboard.json

Behind the scenes:

Each shot is submitted to Seedance 2.0 in parallel (3-10 min generation)
Generated clips are downloaded and normalized to the target resolution
FFmpeg concatenates clips, burns SRT subtitles, and mixes BGM
Final MP4 is saved to disk — ready to post

Four CLI Commands

Command	Use Case
`generate`	Generate a single AI video clip
`render`	FFmpeg render: concat + subtitles + BGM → MP4
`compose`	CapCut Mate: create Jianying draft with effects
`pipeline`	End-to-end: storyboard JSON → final MP4

OpenClaw Integration

As an OpenClaw skill, AI Video Studio is invoked through natural language:

"Make a 3-shot product video, 16:9, 5 seconds each, with captions."

The agent builds a storyboard, calls studio.py pipeline, and returns the MP4 — through Telegram, WhatsApp, or any channel.

Why FFmpeg Over Cloud Rendering?

Zero dependencies — No Windows machine, no desktop client
Sub-second render — Near-instant concatenation and subtitle burn
Server-side — Runs on any Linux box with ffmpeg
Free — No cloud rendering fees
