title: Python ImageIO Gif Set Delay Between Frames
body: <p>I am using ImageIO: <a href="https://imageio.readthedocs.io/en/latest/userapi.html" rel="noreferrer">https://imageio.readthedocs.io/en/latest/userapi.html</a> , and I want to know how to set delay between frames in a gif.</p>
  
  <p>Here are the relevant parts of my code.</p>
  
  <pre><code>import imageio 
  . . . 
  imageio.mimsave(args.output + '.gif', ARR_ARR)
  </code></pre>
  
  <p>where <code>ARR_ARR</code> is an array of <code>numpy uint8</code> 2d array of couplets.</p>
  
  <p>To be clear, I have no problem writing the gif. I cannot, however, find any clarification on being able to write the amount of delay between frames.</p>
  
  <p>So, for example, I have frames 0 ... 9</p>
  
  <p>They always play at the same rate. I would like to be able to control the number of milliseconds or whatever unit between frames being played.</p>
