title: Zoom, Crop and Cut videos iPhone
body: <p>I have a small video clip in my iPhone Application on which I wish to carryout the following operations -</p>
  
  <ol>
  <li>Zoom - I should be able to zoom in and out the video by pinching gestures.</li>
  <li>Crop - I should be able to Crop the video length after increasing/decreasing its speed.</li>
  <li>Cut - I should be able to drag a window on any part of the video and cut that piece of video which is within the window as a separate video.</li>
  </ol>
  
  <p>Since the video size is very small (less than a minute), all I can think of is converting the video into images by extracting each frames and then carry-out the above operations. 
  Can anyone suggest a better idea?</p>
  
  <p>Thanks </p>
