title: How to change saturation, brightness, contrast of a recorded video in ios
body: <p>I am developing an app which <strong>edit videos</strong>. There is no problem when I record video because, initially I will set all the settings like <strong>saturation</strong>, <strong>brightness</strong>, <strong>contrast</strong> etc. </p>
  
  <p>But the problem is with recorded videos. I am unable to change all the above <strong>properties</strong> of videos which are recorded already.</p>
