The Ellipse effect allows you to highlight an object in the video by setting out an ellipse-shaped object which is covered with specified color while the rest of the picture remains untouched.
In the Properties Window you can change the effect properties.
If you want to include a filled ellipse to your video, stay in the brush mode set by default and select the color and alpha value (transparence), as well as a brush type from the following available ones: solid, gradient, hatch, texture.
If you would like to include only an outline of the ellipse, you should click the button to choose the color, alpha value (transparence) and the pen thickness on the size slider. You can also check the Apply Antialias box to smooth the outline of the ellipse.

It's possible to change the location and size of the added ellipse within the Preview Window.
To move the ellipse to some other place on the video picture, you should direct the mouse cursor to the Ellipse Rectangle area (the mouse cursor will turn to the sign) and drag it to the place where you want the ellipse to be situated. To change the size of the ellipse, direct the mouse cursor to one of the black squares (the mouse cursor will turn to the sign) and drag it within the preview area.
