by movie camera or recorded by a video camera.

The embedding of video in multimedia applications is a powerful way to convey information which can incorporate a personal element which other media lack (отсутств.)

Video improves, dramatizes, and gives impact to your multimedia application.

The advantage of integrating video into a multimedia presentation is the capacity to effectively convey a great deal of information in the least amount of time.
