- Video files are stored as a series of images that are played one after another, up to 60 times per second.
- Video files attempt to find large areas of an image that do not change between frames. This allows the video file to only update the pixels that have changed, saving huge amounts of storage.
- To calculate the storage requirements of a video file, multiply its resolution (number of pixels in the image) times the frames per second, times the bit depth (number of bits per pixel), times the length in seconds.
