Is MPEG-4 ready for the masses ?
MPEG-4
allows you to optimise every part of the movie, while maintaining compatibility.
MPEG-4 contains a wide variety of compression technologies to deliver the best
performance for every kind of content. So what’s in it for you? Well, better
quality, less disk usage and the ability to get better quality movies streaming
over your internet connection. Currently many technologies are being developed
to ensure better compression of audio and video and some of them are already
available right now! In the end MPEG-4 should guarantee that MPEG-4 files will
play on every MPEG-4 compatible device, whether it’s brand A or brand B. There
are of course limitations. A movie for a home theatre set might not play well
(or at all) on your mobile phone. But, as said before, the profiles will make
sure that you know this in advance.
Some of the current MPEG-4 available
codecs are DivX, XviD and Quicktime. In a recent press release Ahead has stated
that it will also bring us a codec that is able to compete with these formats.
For audio the best known codec is probably AAC (Advanced Audio Coding), which
was also implemented in MPEG-2. However, the MPEG-4 version will likely produce
much better results.
