# Video from numpy array in Jupyter Notebook

[![PyPI version](https://badge.fury.io/py/notebook-video-writer.svg)](https://badge.fury.io/py/notebook-video-writer)   

  

Create videos from numpy arrays in a jupyter notebook  

Packaged version of [Alexander Mordvintsev's Colab Snippets](https://github.com/znah/notebooks/blob/master/external_colab_snippets.ipynb)

### Install    

  

`pip install notebook-video-writer`  

### Dependencies  

  - Must have ffmpeg installed  

### Usage  

```python

import numpy as np

# optionally wrap with tqdm for progress bar

from tqdm import tqdm

from notebook_video_writer import VideoWriter

with VideoWriter(fps=40) as vw:

    for i in tqdm(range(100)):

        frame = np.random.rand(256,256,3)

        vw.add(frame)

```    

This will immediately display the video inline below the cell:

An mp4 file is also saved to the current directory. Default name is `_autoplay.mp4`, but can be set with `name` keyword arg.
