    <p>Takes start and stop points of a YouTube video, down to the frame, and gives the time between them in the format
      <code>1h 23m 45s 678ms</code>. Source code is <a
        href="https://github.com/slashinfty/yt-frame-timer">available</a>.

    <h3 id="video-framerate">Video Framerate</h3>
    <p>Right click the YouTube video and select “Stats for nerds.” The third line is “Current / Optimal Res” - find the
      two numbers after the @ and enter them for framerate.</p>
