What Is MPEG?

When I embarked on my new venture after retiring from the mortgage banking world, I knew little about what I had to learn. What I DID know was I wanted be way ahead of my competition. I wrote this article to show others what some of the terminology is relative to "Video" and nothing else. Because, remember...posting video is THE wave of the future for online marketing.
I wrote it because if you're going to grasp Web 3.0, you need to know how to effectively work with video. Don't worry...if a former paper pusher like me can learn it fast, so can you.

Compression Standards

MPEG stands for the Motion Picture Experts Group MPEG is an ISO/IEC working group, established in 1988 to develop standards for digital audio and video formats. There are five MPEG standards being used or in development. Each compression standard was designed with a specific application and bit rate in mind, although MPEG compression scales well with increased bit rates. They include:

MPEG-1
Designed for up to 1.5 Mbit/sec
Standard for the compression of moving pictures and audio. This was based on CD-ROM video applications, and is a popular standard for video on the Internet, transmitted as .mpg files. In addition, level 3 of MPEG-1 is the most popular standard for digital compression of audio--known as MP3.

MPEG-2
Designed for between 1.5 and 15 Mbit/sec
Standard on which Digital Television set top boxes and DVD compression is based. It is based on MPEG-1, but designed for the compression and transmission of digital broadcast television. The most significant enhancement from MPEG-1 is its ability to efficiently compress interlaced video.

MPEG-4
Standard for multimedia and Web compression. MPEG-4 is based on object-based compression, similar in nature to the Virtual Reality Modeling Language. Individual objects within a scene are tracked separately and compressed together to create an MPEG4 file. This results in very efficient compression that is very scalable, from low bit rates to very high.

MPEG -7
This standard, currently under development, is also called the Multimedia Content Description Interface. When released, this standard will provide a framework for multimedia content that will include information on content manipulation, filtering and personalization, as well as the integrity and security of the content.

MPEG-21
Work on this standard, also called the Multimedia Framework, has just begun. MPEG-21 will attempt to describe the elements needed to build an infrastructure for the delivery and consumption of multimedia content.
JPEG stands for Joint Photographic Experts Group. JPEG is a lossy compression technique used for full-color or gray-scale images, by exploiting the fact that the human eye will not notice small color changes.

DV is a high-resolution digital video format used with video cameras and camcorders. The standard uses DCT to compress the pixel data and is a form of lossy compression. The resulting video stream is transferred from the recording device via FireWire (IEEE 1394), a high-speed serial bus capable of transferring data up to 50 MB/sec.

Pay Attention Here Folks

DivX Compression

DivX is a software application that uses the MPEG-4 standard to compress digital video, so it can be downloaded over a DSL/cable modem connection in a relatively short time with no reduced visual quality. The latest version of the codec, DivX 4.0, is being developed jointly by DivXNetworks and the open source community. DivX works on Windows 98, ME, 2000, CE, Mac and Linux.

Lossy compression - reduces a file by permanently eliminating certain redundant information, so that even when the file is uncompressed, only a part of the original information is still there.

Codec - A video codec is software that can compress a video source (encoding) as well as play compressed video (decompress).

The best compression software I've used is that produced by DivXNetworks.com. It's very inexpensive and without it, you will NEVER upload a single video. Ever. The files are simply too big pre-compression. Without compression, it's like trying to shove a football through a garden hose.

There you have it. Use this information to blow by your competition like I have and you'll enjoy marketing on the internet like never before.
