Description
The monster
For this video, the monster should not be scary by itself. You will make it scary. Suggestions that others have used: A stuffed animal, a plant, a soccer ball, a Game Boy, or a food item. . If you want your story to have a happy ending, pick a monster that can be beaten in an interesting way. A Game Boy might run out of battery power. A soccer ball might deflate.
The story
The genre is simple: Introduce a main character or characters the audience can identify with. Introduce a monster. Monster attacks main character. Main character defeats monster. Everyone lives happily ever after except the monster. Of course, there are many variations on this theme. Sometimes, the monster is the hero in the end.
Shooting the video
You can make this project most effective by using camera angles. Shoot from the monster's POV (point of view). A shot of the hero (or victim) is more interesting when shot from above — making the character seem vulnerable or powerless — or from below, which makes the character seem more powerful.
Editing your video
This is where you make the project really special. The monster point-of-view shots can be made scarier by adding the color red to the screen. The videos from a certain POV can be tilted, or warped. Adding a color (usually red) and a sound (breathing or a heartbeat are popular) are easy and very effective.
