This is an express tutorial which just deals with adding an effect container and doing something simple with it.

Here's a photo of a duck that you can use if you want.

Import the duck photo, or other photo or video into ZS4.  If you haven't done this before, maybe try one of the other tutorials first.

Go to the f/x tab and navigate to the oval outside effect container (effects/video effects/effect containers/shapes sharp).  Drag it onto the duck track.


 
 
Now go back to the f/x tab and find the desaturate effect (effects/video effects/pixel filters/simple filters).  Drag this into the oval outside container.


 
 The oval outside container comes with a default oval but you can change it from the "current" tab by pressing the oval toggle in and then drawing an oval on the image there. (Select oval outside as current track first)


 
 If you want, change the time slider position and draw a new oval somewhere else so that the coloured spot will move.
