To start adding any video effect you should click the Video Effects button in the Create Movie menu pane.

1. Find the Draw Rectangle video effect icon in the Media Library and click to highlight it. It is located in the Draw video effects group.

2. To add the selected video effect to the Timeline please use drag-and-drop method: drag the desired track icon from the Media Library to the Timeline. You can also click the Add To Timeline button.

After that you should set the boundaries and Fade-in and Fade-out limits.

First we should set the video effect boundaries. In our example we want our video to start going into the background from the 12th second till the end. So, the boundaries should be set as shown:

Fade-in is the area where the effect starts being reflected on your video. In the area of maximum representation the effect is applied to 100% capacity. In the Fade-out area the effect is being reduced until it completely disappears.

After you choose the effect you want to apply, the program automatically sets the fade-in and fade-out boundaries. You should change them by clicking the left mouse button and dragging the boundaries inwards or outwards like this:

   You can also use the Effect Parameters tab located right under the Main Preview to set the parameters of this video effect. So far as we want our video to go into black background, there's no need to change color parameter - black is the default color.
