# Video Frames (ffmpeg)
Extract a single frame from a video, or create quick thumbnails for inspection.
## Quick start
First frame:
```bash
ffmpeg -hide_banner -loglevel error -y \
-i /path/to/video.mp4 \
-vf "select=eq(n\,0)" \
-vframes 1 \
/tmp/frame.jpg
```
At a timestamp:
```bash
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:
```bash
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 `.jpg` for quick sharing; use `.png` for crisp UI frames.
- Use `-hide_banner -loglevel error` to suppress verbose ffmpeg output.
