SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires ffmpeg, and includes scripts (resource) components.

What problem does it solve?

This skill solves the tedious task of extracting frames from video files for thumbnails and quick previews, enabling rapid visual checks and frame sampling in media pipelines.

Core Features & Use Cases

  • Frame extraction: capture a single frame at the start or a specific timestamp from video files.
  • Thumbnail/Preview generation: produce compact visuals for dashboards or QA reviews.
  • Deterministic frames: request a specific index or timestamp to ensure repeatable outputs in automated pipelines.

Quick Start

To generate the first frame from a video: {baseDir}/scripts/frame.sh /path/to/video.mp4 --out /tmp/frame.jpg To capture a frame at 00:00:10: {baseDir}/scripts/frame.sh /path/to/video.mp4 --time 00:00:10 --out /tmp/frame-10s.jpg
