What are Video Files? Definition and list of extensions

Video files are collections of images, audio, and other data. Video signal attributes include pixel dimensions, frame rate, audio channels, and more. There are many ways to encode and save video data.

In general, video files have the following characteristics:

  • Box Size: This is the pixel dimension of the frame.
  • The aspect ratio: Ratio between width and height.
  • Frame rate: Rate at which frames are captured and intended for playback.
  • Quality: The bit rate or data rate is the amount of data used to describe the audio or video portion of the file. It is measured in units per second: kilobytes, megabytes, or gigabytes per second. In general, the higher the bitrate, the better the quality.
  • Audio Sample Rate: This is the frequency the audio is sampled when converted from an analog source to a digital file.

Video files are made up of a container such as AVI or MOV, the audio and video signal, and a codec (software to encode and decode the video signal)

The most used video file extensions are: .mpg, .mov, .wmv, and .rm.
