If you've ever seen "Vertigo" or "Poltergeist," you know that lengthening a hall or a yard makes for great movie making. And, you can create a similar scene even on no budget. Film your actor running towards you. Then in the editing room, loop this scene over a few times. It will make the area where you're filming look really long.
You can also edit the clips to make it seem as if they're getting closer each time by splicing together the same sections of video. If you don't like the way that the loop looks, edit in other clips, such as some other action scene or people reacting to the actor running at them.
Homemade videos are fun and can be rather inexpensive. If you add these simple homemade special effects suggestions to your repertoire, you'll be making your own eye-catching, independent films.
