Digital Video

Prior to the introduction of digital video, video was recorded in analogue format on magnetic tape, similar to the tape used for audio recordings. The first digital video cameras also recorded on magnetic tape, but this was later replaced by recordable CDs or DVDs and eventually by hard disks and flash memory cards. Most modern video cameras record to SD cards or similar media.

One of the great benefits of digital video is that it is easy to edit, in comparison to analogue video. The video files are normally copied to a computer and edited using video editing software, such as Adobe Premiere, Avid Studio or Final Cut, although some video cameras allow a limited range of video editing operations to be carried out on the camera itself.

Typical editing operations include cutting and pasting scenes, and adding titles, transitions between scenes and special effects. Modern video technology also allows the use of web-based video for video conferencing and for playback of videos from sites such as YouTube.
