title: How to downsample all the videos in a folder?
body: <p>I had asked this question before, I have a solution using the <em>moviepy</em> library. But, this is taking a lot of time.<br />
  I know that when I use ffmpeg via the terminal, the down sampling process is much faster.</p>
  <pre><code>command = (
              f&quot;ffmpeg -n -i {'inputvideo_path'} -filter:v &quot;
              f&quot;scale={width}:{height} {{}}-c:a copy {output_path}&quot;
          )
  </code></pre>
  <p>I am looking for the implementation in ffmeg library</p>
