# Add watermark to media

## Example Prompt

> "Add my logo as a watermark to the bottom-right corner of this image at 50% opacity."

## What the Agent Does

Applies a text or image watermark on top of an existing image, GIF, or video using the watermark.py library — a Python wrapper around FFmpeg. The agent accepts a source file and a watermark (either an image file or a text string), then configures placement, size, and opacity before writing the output.

Users can control:
- **Position** — top-left, top-right, bottom-left, bottom-right, or center
- **Opacity** — how transparent the watermark appears over the base media
- **Scale** — how large the watermark renders relative to the source

Install with `pip install watermark.py` and ensure `ffmpeg` is available on the system. Then hand the agent a file path and describe where and how to stamp it.
