What is MP4?
MPEG-4 Part 14, formally ISO/IEC 14496-14:2003, is a multimedia container format
standard specified as a part of MPEG-4. It is most commonly used to store digital
audio and digital video streams, especially those defined by MPEG, but can also
be used to store other data such as subtitles and still images. Like most modern
container formats, MPEG-4 Part 14 allows streaming over the Internet. The official
filename extension for MPEG-4 Part 14 files is .mp4, thus the container format
is often referred to simply as MP4.
MPEG-4 is a patented collection of methods defining compression of audio and
visual (AV) digital data. It was introduced in late 1998 and designated a standard
for a group of audio and video coding formats and related technology agreed upon
by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under
the formal standard ISO/IEC 14496 - Coding of audio-visual objects. Uses
of MPEG-4 include compression of AV data for web (streaming media) and CD distribution,
voice (telephone, videophone) and broadcast television applications.
MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related
standards, adding new features such as (extended) VRML support for 3D rendering,
object-oriented composite files (including audio, video and VRML objects), support
for externally-specified Digital Rights Management and various types of interactivity.
AAC (Advanced Audio Coding) was standardized as an adjunct to MPEG-2 (as Part
7) before MPEG-4 was issued.
MPEG-4 is still a developing standard and is divided into a number of parts.
Companies promoting MPEG-4 compatibility do not always clearly state which "part"
level compatibility they are referring to. The key parts to be aware of are MPEG-4
part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid,
Nero Digital and 3ivx and by Quicktime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264
or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by Quicktime
7, and by high-definition video media like Blu-ray Disc).
What is AC3?
Dolby Digital, or AC-3, is the common version containing up to six discrete channels
of sound. The most elaborate mode in common usage involves five channels for normal-range
speakers (20 Hz - 20,000 Hz) (right front, center, left front, right rear and
left rear) and one channel (20 Hz - 120 Hz) for the subwoofer driven low-frequency
effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates
up to 48kHz. Batman Returns was the first film to use Dolby Digital technology
when it premiered in theaters in Summer 1992. The LaserDisc version of Clear and
Present Danger featured the first Home theater Dolby Digital mix in 1995.
