Video Editor
Skill by cntuang
Why use this skill?
Automate your video workflow with OpenClaw. Edit, trim, merge, and convert video files using FFmpeg directly through your AI agent. Fast, powerful, and easy to use.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/cntuang/video-editorWhat This Skill Does
The Video Editor skill is a robust wrapper around the powerful FFmpeg engine, specifically designed for the OpenClaw AI agent to manipulate video and audio content. It streamlines complex video processing tasks into simple, command-line interface calls. The skill acts as an automated studio assistant, capable of performing core editing functions such as non-destructive trimming, file format transcoding, stream merging, audio extraction, resolution scaling, and creative effects like subtitles and playback speed modification. By abstracting away the complex syntax of FFmpeg flags and filter chains, it allows users to perform professional-grade video editing directly within their conversational workflow.
Installation
To utilize this skill, ensure that the binary dependencies are present on your system. Run brew install ffmpeg to install both the ffmpeg and ffprobe tools. Once installed, activate the skill via the OpenClaw management console using clawhub install openclaw/skills/skills/cntuang/video-editor. This setup ensures the environment is primed for high-performance media transcoding and analysis.
Use Cases
This skill is perfect for creators and developers who need to batch-process media. Common use cases include: cleaning up long raw recordings by trimming dead space, converting high-definition camera footage into compressed web-friendly formats, burning hardcoded subtitles for accessibility or social media compliance, and normalizing media for cross-platform distribution. It is particularly effective for generating social media highlight reels by chaining multiple operations like cutting and cropping.
Example Prompts
- "Cut the first 10 seconds of my video named presentation.mp4 and save the result as intro.mp4."
- "Extract the audio from interview.mov and save it as an MP3 file."
- "Take the video clip_raw.mp4, resize it to 1080p resolution, and speed up the playback to 1.5x, saving it as output.mp4."
Tips & Limitations
When merging files, ensure all source videos share identical codecs, frame rates, and resolutions to prevent encoding errors. For complex transformations, the skill relies on your system's hardware; large file processing may take time depending on your CPU power. Avoid using this skill for real-time video streaming, as it is designed for batch file-based operations. Always verify disk space availability before beginning massive batch conversion tasks.
