12 Facts About VCD

VCD enjoyed a brief period of success, with a few major feature films being released in the format .

However the introduction of the CD-R disc and associated recorders stopped the release of feature films in their tracks because the VCD format had no means of preventing unauthorized copies from being made.

The first track of a VCD is in CD-ROM XA Mode 2 Form 1, and stores metadata and menu information inside an ISO 9660 filesystem.

Shortly before the advent of White Book VCD, Philips started releasing movies in the Green Book CD-i format, calling the subformat CD-i Digital Video .

XVCD is the name generally given to any format that stores MPEG-1 video on a compact disc in CD-ROM XA Mode 2 Form 2, but does not strictly follow the VCD standard in terms of the encoding of the video or audio.

Normal VCD is encoded to MPEG-1 at a constant bit rate, so all scenes are required to use exactly the same data rate, regardless of complexity.

However, video on an XVCD is typically encoded at a variable bit rate, so complex scenes can use a much higher data rate for a short time, while simpler scenes will use lower data rates.

KVCD is an XVCD variant that requires the use of a proprietary quantization matrix, available for non-commercial use.

KVCD is notable because the specification recommends a non-standard resolution of 528×480 or 528×576.

DVCD or Double VCD is a method to accommodate longer videos on a CD.

VCD's growth has slowed in areas that can afford DVD-Video, which offers most of the same advantages, as well as better picture quality due to its larger storage capacity.

However, VCD has simultaneously seen significant new growth in emerging economies like India, Indonesia, South America, and Africa as a low-cost alternative to DVD.
