Now we will change the length of the rectangle from this video. Locate the rectangle from the slide window. As you can see from the picture below, this rectangle is displayed from the 3rd second for 5 seconds. Move your mouse to the beginning or end of the slide bar and your mouse pointer will be changed.


You can drag this bar to wherever you want the rectangle to be displayed. I will change this to be displayed from 4th second for 2 seconds.

If you don’t want to change the display time of the object but move it to an earlier or later frame, move the slide bar to the left or right. I have moved the rectangle to 1 second earlier.
You can also click the Zoom in/out button from slide window to see more or less frames.
