Video Frames
Extract individual frames or thumbnails from video files using ffmpeg, with support for timestamp-based extraction and multiple output formats.
Peter Steinbergerv1.0.0npx clawhub@latest install video-framesVideo Frames lets you pull single frames from any video file using ffmpeg. You can extract the first frame for a quick thumbnail or specify an exact timestamp to capture a specific moment. Output supports both JPG (for quick sharing) and PNG (for crisp UI screenshots).
工作原理
The skill provides a shell script that wraps ffmpeg commands. You point it at a video file, optionally specify a timestamp with --time, and choose an output path with --out. The script handles the ffmpeg invocation and outputs the extracted frame in your chosen format.
