Pan and Zoom on a still image

There is no one click solution for zooming still images.

Below is the basic idea of what I have done when zooming a still image is needed.

• Make a high quality capture of the "zoom area" at maximum size.
• Have a new slide with the unzoomed area.
• Have a layer covering your capture area that is 50% gray and 50% transparent (adjust as needed).
• Have the gray transparent area (under the zoom capture image) become visible right before the zoom.
• Place the zoom area capture on the slide and scale it down so it fits on the unzoomed capture.
  • Adjust the zoom area capture on the timeline be visible if needed.  
• Then go under Timing and use either Scale or Scale To (depending on the effect you are looking for) and Motion Path / CustomLines to move the zoom effect into the position you want. 

Did you try the Zoom object?
