MPEG
You have used 79% of a disc running at Standard Speed. (Standard quality compression rate).
Well it's the standard for lossy compression of Audio and Video. It is used to compress VHS video/CD audio down to 1.5Mbit/s without excessive quality loss. The best-known part of the MPEG-1 standard is probably MP3. A very common lossy compression format in the modern world.

There are many formats you can convert video to to compress it. ex. MPEG, WMV, DIVX/XVID, etc. Today a very popular one is XVID compression, based on DIVX. To compress video to XVID one popular method is to use the free application "AutoGK'. == == DivX
The video coding format MPEG is used through the web for video compression. MPEG goes up to MPEG- Part4 that is shortened to MP4.

The compression used will depend on what you want to do with the video. MPEG-2 is used for burning to DVD's. MPEG-4/H264 can be used for streaming from a website. The length of the video and available bandwidth are also considerations when selecting a suitable compression format.
It depends on the context. Many people will swear by one codec or another, but it really just depends on what the situation calls for. Nowadays, for the web flash video is pretty much the standard. Flash 8 (On2 VP6 video codec) provides better compression (more quality for lower bitrate) so use that if you can. If the video is for desktop use then the H.264 is becoming the standard.

Following are the advantages of Video Compression:- Occupies less disk space.- Reading and writing is faster.- File transferring is faster.- The order of bytes is independent.Following are the disadvantages of video compression”- Compilation need to be done again for compression.- Errors may occur while transmitting data.- The byte / pixel relationship is unknown- Has to decompress the previous data.
