Editing Skills | Masking

  Good feature in some horror films such as "Mirrors", uses the effect of cloning. This is when the same person is in a shot, twice, and are doing different things. It can be used in a comical way, shown below;






It can also be used in a scary way, such as in "The Black Swan";




I wanted to test this effect, in order to be able to use it in our trailer when we come to film/edit. therefore I watched a couple tutorials online and found out how to do it. Our result is shown below;

 How I made it

 When you have imported your two video clips, you have to find the effect "Linear wipe". What this does is allows you to cut an overlaying clip in half, as shown below. The black section on the left hand side would usually be the underlying layer that will be displayed, making it appear as one clip.

In order to apply the cut, you use the percentage scroll on the "transition completion" setting under "Effect Controls". This will allow you to select where about the clip is cut, vertically down the middle. I put my setting to around 50% to ensure it was even and it wasn't noticeable.

After applying the effect, this was my final result.
