What is an Application Standard?
There are two video recording applications for DVD discs: DVD-Video, offering maximum
compatibility, and DVD-VR (Video Recording), for simple in-camera editing.
An application standard, such as DVD-Video or DVD-VR, is not the same as a physical standard, such as DVD-ROM,
DVD-R, or DVD-RW. A physical standard refers to the disc itself; application standards refer to the recording process,
and determine the recording method to be used for various purposes. For the purpose of recording video with
maximum flexibility for playback compatibility, the DVD-Video application standard is used. For recording video with
limited playback compatibility but additional in-camera editing, the DVD-VR (Video Recording) application standard is
used.

About Each Application Standard
DVD-Video
DVD-Video was first developed for commercial DVD movies. DVD-Video creates recordings that cannot be edited in the
camcorder. It allows up to 2 hours of moving images and sound. MPEG 2 coding is used for video; Dolby AC-3 coding is
used for sound. DVD-Video recordings can be played back on virtually all DVD players.
DVD-VR
DVD-VR modified the concept of DVD-Video, allowing user-friendly editing functions for consumer recording. DVD-VR
recordings can be played back on a limited number of DVD players that support the DVD-VR application standard.
