- Extract frames and short clips from local video files with ffmpeg. Use when you need quick visual checkpoints without opening a full editor.
Video Frames
Use this skill to pull exact frames or short clips from a local video.
Workflow
- Confirm
ffmpegis installed and the input file exists. - Extract one frame by timestamp or by frame index.
- Optionally export a short clip for review context.
- Keep outputs in a deterministic artifact folder for repeatable checks.
Frame Extraction
python3 "$CODEX_HOME/skills/video-frames/scripts/video_frames.py" frame \
--input /path/to/video.mp4 \
--time 00:00:12 \
--out /tmp/frame-12s.jpg
By frame index:
python3 "$CODEX_HOME/skills/video-frames/scripts/video_frames.py" frame \
--input /path/to/video.mp4 \
--index 0 \
--out /tmp/frame-0.png
Short Clip Export
python3 "$CODEX_HOME/skills/video-frames/scripts/video_frames.py" clip \
--input /path/to/video.mp4 \
--start 00:00:10 \
--duration 5 \
--out /tmp/clip-10s-15s.mp4
Guardrails
- Local files only; do not fetch remote media in this lane.
- Keep extraction deterministic (
--timeor--indexmust be explicit in reviews). - Preserve source files; write only to target output paths.
Scope Boundary
Use this skill only for frame/clip extraction and lightweight visual inspection.
Do not use this skill as a replacement for full timeline editing or compositing.

VerifiedTrustedCommunity
Run a defender-first security sweep on code, configs, prompts, model/tooling surfaces, or third-party contribution lanes. Use when a request involves safe bug, leak, zero-day-class, exploit, or hack hunting for protection, when contributing to outside repositories and you want a focused security pass, or when touching auth, secrets, permissions, network exposure, prompt/tool boundaries, data flow, or update/build surfaces. This skill is defensive only and must never be used for weaponization or unauthorized access.
