The document describes the process of creating a green screen composite video in Adobe Premiere Pro. Key steps include importing video clips and audio, layering clips on the timeline with the girl clip on top of the beach clip and the explosion clip on top of both, using the Ultra Key effect to select the green background color, adjusting highlight and shadow controls to refine the matte, and syncing an explosion sound effect to the visual explosion.

1. Green screen
Premiere Pro

2. Firstly, I imported the clips and the audio into the project panel and then dragged the clip if the beach into the timeline.

3. I dragged the clip of the girl into the timeline and placed in on top of the clip of the
beach.

4. In the effects menu, I selected the ultra key and displayed the effect controls

5. I then changed the key colour from black to green, using the eye dropper tool to select
the green in the background.

6. I also changed the output from composite to alpha channel and used the matte generation effects to adjust the highlight
and shadow to make the background more opaque.

7. I dragged the explosion clip into the timeline and placed in on top of the other clips.

8. Once again I used the ultra key to change the key colour to green and then adjusted
the highlight and shadow.

9. I cropped the clip of the explosion so that the explosion occurs at the end of the clip and then placed it on top of the
pineapple.

10. Lastly, I added the sound of the explosion into the timeline and cropped it so the sound goes off at the same time the
explosion does.
