In the previous task you performed various three-point edits in order to embellish the conflict between the insect and the snake. However, the insect's escape from the snake is a little sudden, so you will add a portion of another snake clip (Snake_Rear.avi), but using a four-point edit in order to control the new clip's duration on the Timeline.
Four-point edits are used to speed up or slow down a clip so that it can fit into a user-defined space on the Timeline. In this case you will use it to slow the content of a clip down by 50 percent, but keep the continuity of the action constant.
After the insect escapes it is also attacked by a frog; however, this is so quick the viewer will never have a chance to see it. To correct this you will combine three- and four-point edits to slow down part of this new clip (BB_Flyby.avi) to make the frog's attack a more prominent feature of the scene.
