Most movies are made so they can be watched at home or on a movie screen at movie theaters. Movies are shown in movie theaters a few weeks or months after or before the movie is released. Movies can be marketed using media.
Some movies are shown on television broadcasting stations.
When a movie projector, a computer, or a television shows the pictures at 24 frames a second, it looks like the things shown in the set of pictures are moving. Sound is usually recorded at the same time as the pictures are, but sometimes they are added later.
Movies are filmed with movie cameras or video cameras. Movie cameras take pictures very quickly, and they usually take 24 or 25 pictures, or frames every second.
The sounds in a movie are usually people talking, the soundtrack, and sound effects. In the 20th century the camera used photographic film.
