Digital Representation of Data: Video

Need more help with your HSC study? Check out my new digital study guides here:

Video is a data type and form of media which displays multiple images in a sequence which gives the effect of movement. Video can be collected by digital cameras, which these days can be found built in to many mobile devices, and edited using video editing software. Video is often paired with audio for the creation of movies, though we will be looking at video as an independent form of media for its data representation. Data which needs to be recorded in order to create a video file includes:

Frames per Second (FPS): the number individual images that will be played in sequence each second in a video file. The standard for mainstream movies is 24 fps, whereas video games strive for 60 fps.

Image Resolution: the amount of horizontal and vertical pixels which make the set resolution of the images used to create the video. (horizontal x vertical pixels)

Bit Depth: the number of bits per pixel. The greater the bit depth, the more colours available to make up each image. The bit depth is mapped to the binary calculation of data, meaning the more colours available increases the file size exponentially due to the base 2 calculation.

Time: Duration of the Video file in seconds.
