Video Frames (ffmpeg)
Extract a single frame from a video, or create quick thumbnails for inspection.
Quick start
First frame:
ffmpeg -hide_banner -loglevel error -y \
-i /path/to/video.mp4 \
-vf "select=eq(n\,0)" \
-vframes 1 \
/tmp/frame.jpg
At a timestamp:
ffmpeg -hide_banner -loglevel error -y \
-ss 00:00:10 \
-i /path/to/video.mp4 \
-frames:v 1 \
/tmp/frame-10s.jpg
By frame index:
ffmpeg -hide_banner -loglevel error -y \
-i /path/to/video.mp4 \
-vf "select=eq(n\,42)" \
-vframes 1 \
/tmp/frame42.jpg
Notes
- Prefer
-ss+ timestamp for "what is happening around here?". - Use
.jpgfor quick sharing; use.pngfor crisp UI frames. - Use
-hide_banner -loglevel errorto suppress verbose ffmpeg output.
