What is mpeg-4?Originally Posted by secretman73
This is a most advanced system for multimedia representation and distribution.
This offers a variety of compression options, including low-bandwidth formats for transmitting to wireless devices as well as high-bandwidth for studio processing.
MPEG-4 incorporates AAC, which is a high-quality audio encoder. MPEG-4 AAC is widely used as an audio-only format.
A major feature of MPEG-4 is its ability to identify and deal with separate audio and video objects in the frame, which allows separate elements to be compressed more efficiently and dealt with independently. User-controlled interactive sequences that include audio, video, text, 2D and 3D objects and animations are all part of the MPEG-4 framework.
