# unwrap.py
2+
3+
Unwraps a video into a flattened texture using ffmpeg.
4+
5+
### Prerequisites
6+
```pip3 install pillow```
7+
8+
ffmpeg, available from [here.](https://ffmpeg.org)
9+
10+
### How to run the script
11+
Move the videos you want unwrapped into the media directory, then run:
12+
13+
```python3 unwrap.py```
14+
15+
### Screenshot/GIF showing the sample use of the script
16+
Example video is located in media.
17+
18+
This might not look like much, but with better source videos the unwrapped picture will be more meaningful too.
