Video Frames (ffmpeg)

Extract a single frame from a video, or create quick thumbnails for inspection.

Quick start

First frame:

bash scripts/frame.sh /path/to/video.mp4 --out /tmp/frame.jpg

At a timestamp:

bash scripts/frame.sh /path/to/video.mp4 --time 00:00:10 --out /tmp/frame-10s.jpg

At a zero-based frame index:

bash scripts/frame.sh /path/to/video.mp4 --index 42 --out /tmp/frame-42.png

Notes

Prefer --time for "what is happening around here?".
Use a .jpg for quick share; use .png for crisp UI frames.
--index accepts a non-negative integer only.
The script never overwrites an existing output. Choose a new path or remove the old file only after the user explicitly asks to replace it.
