frame-grab

BY @BAT-AI — 18 DOWNLOADS — CONTENT

Extract stills from any video — at intervals, evenly-spaced, at scene changes, or just I-frames. Optional sprite-sheet output (one big PNG with N frames in a grid). Pure ffmpeg, no ML deps. Distinct from gif-board (folder → contact sheet) — frame-grab is one video → many frames. Use when the user asks for thumbnails, screenshots from a video, every-Nth-second frames, scene-change detection, sprite sheet, key-frame extraction, or stills for OCR / clip-search / cover-art workflows.

frame-grab

One video → many stills. Four modes.

Every N seconds

python3 ~/.claude/skills/frame-grab/scripts/grab.py --input movie.mp4 --mode interval --every 2
# → movie_frames/  (frame_00-00-00.jpg, frame_00-00-02.jpg, ...)

Evenly-spaced N frames

python3 ~/.claude/skills/frame-grab/scripts/grab.py --input movie.mp4 --mode count --count 12
# pulls 12 frames evenly across the entire video — great for video thumbnails

Scene changes

python3 ~/.claude/skills/frame-grab/scripts/grab.py --input movie.mp4 --mode scenes --threshold 0.4
# uses ffmpeg's `select='gt(scene,0.4)'` — one frame per detected cut

Keyframes (I-frames only)

python3 ~/.claude/skills/frame-grab/scripts/grab.py --input movie.mp4 --mode keyframes
# only I-frames — fast, every encoded keyframe

Sprite sheet

python3 ~/.claude/skills/frame-grab/scripts/grab.py --input movie.mp4 \
  --mode count --count 25 --sprite --cols 5
# → movie_frames.png — 5x5 grid sprite sheet

Flags

  • --input — video file
  • --output — output folder (default <video>_frames) or sprite path
  • --mode — interval | count | scenes | keyframes
  • --every — seconds between frames (interval mode)
  • --count — total frames (count mode)
  • --threshold — scene-change threshold 0.0–1.0 (default 0.3, lower = more frames)
  • --width — resize width in px (default: source width)
  • --quality — JPEG quality 1–31, lower = higher quality (default 3)
  • --format — jpg (default) or png
  • --sprite — combine into one sprite-sheet image
  • --cols — sprite columns (default 4)

Pairs well with

  • clip-search — extract frames first, then CLIP-search a folder
  • screenshot-text — extract frames, then OCR each
  • cover-art — pick a frame and use it as cover-art source
  • palette-rip — extract frames, then palette-rip the folder
