frame_002.jpg
```
, etc.
Prints video metadata (duration, resolution, frame count)

Workflow

Run
```
extract_frames.sh
```
on the video file
Read key frames using the
```

```
tool to view images
For comprehensive analysis, sample frames at regular intervals (e.g., every 5th frame)
Describe what you see in each frame to build understanding of the video

Tips

For short videos (<1 min): Review all frames
For medium videos (1-5 min): Sample every 3-5 frames
For long videos (>5 min): Sample every 10+ frames, focus on scene changes
