SVCD stands for Super Video CD and is the successor to Video CD. The movies on DVD have a 200% sharper picture and far better sound quality than VCDs.ĭVD has gained tremendous popularity with its high-quality video and high storage capability.
#STADARD APPLE VIDEO FORMAT MOVIE#
A two hour movie that requires 2 VCDs can be recorded only on one DVD. A DVD player or a computer equipped with a DVD drive is required to play DVDs.Ī DVD holds significantly more data than a CD (including a VCD). A DVD stores its audio and video in MPEG-2 format. What is a DVD?ĭVD stands for Digital Versatile Disc. The physical medium used, CD-R or CD-RW, is very inexpensive and widely available. The video quality is better than most other formats and is adequate for typical home viewing. All DVD players, VCD players or a computer with CD-ROM drive can play VCDs. VCD is the most universally compatible format for wide video distribution.

Most stand-alone DVD players can play VCDs. A CD-ROM can hold about 800 megabytes of data. Video and audio are encoded using MPEG-1. MPEG-2 is used for higher resolution video, digital television, and on DVD's.
#STADARD APPLE VIDEO FORMAT PORTABLE#
One of the MPEG-1 audio compression standards, MPEG 1 Layer III or MP3, is the most common compression method for audio files used on portable devices. MPEG-1 is used in VCDs and on the web for short video and animation files. In addition, the audio encoding uses something called psychoacoustics-compression removes the high and low frequencies a normal human ear cannot hear. For each frame, it is only necessary to record how it differs from the previous frame, saving storage space. The MPEG-1 video compression method takes advantage of the fact that often, many frames in a row are very similar (showing the same background and objects, for instance, with only an actor's face and hands moving). It significantly reduces the amount of storage needed while keeping acceptable quality. MPEG-1 defines a framework for compressing video and audio. DVDs and VCDs use the MPEG 2 and MPEG 1 standards, respectively. The committee has created several standard methods for encoding video and audio. MPEG is a committee of experts from the audio, video and computer industries developing an evolving series of standards for compression of moving images. It is a group working under the directives of the International Standards Organization (ISO) and the International Electro-Technical Commission (IEC). MPEG stands for ‘Moving Pictures Experts Groups’. To fit the movie on it, you need video compression. Even though the storage capacity of a DVD is huge, the uncompressed video data of a full-length movie would never fit on the DVD.
