100:1
MPEG-4 compression ratios can vary significantly depending on the specific codec used and the content being compressed. Generally, MPEG-4 can achieve compression ratios of 20:1 to 100:1 or more, depending on the desired quality and compression settings. This means that a high-quality video might be reduced from hundreds of megabytes to just a few megabytes while maintaining acceptable visual fidelity. The efficiency of MPEG-4 makes it popular for streaming and storing video content.
The video coding format MPEG is used through the web for video compression. MPEG goes up to MPEG- Part4 that is shortened to MP4.
MPEG
There are several MPEG compression standards, each designed for different applications. Some of the well-known MPEG standards include MPEG-1 (used for video CDs), MPEG-2 (used for DVDs and broadcast television), MPEG-4 (used for web streaming and multimedia content), and MPEG-7 (focused on multimedia content description).

1. JPEG stands for joint photographic expert group and MPEG stands for motion picture expert group. 2. JPEG is used for picture compression and MPEG is used for video compression. 3. JPEG typically achieves 10:1 compression with little perceptible loss in image quality, whereas compression ratio in MPEG is 30:1 for general video using H.263 and 50:1 for general video using H.264/MPEG4. 4. JPEG and MPEG both uses lossy compression.

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.
Many. Basically, MPEG-1 is a compression system that focuses on storing video in a hard disk, that is to say, an "error-free" environment and only is valid for low resolution images. On the other hand, MPEG-2 not only improves the compression factor, but also enhances the capabilities of the antecessor MPEG-1. MPEG-2 can be used not only to store videos (e.g. a DVD) but also can be used for broadcasting. Today's digital television (terrestrial, cable and satellite) uses the compression and signalling of MPEG-2, adapted as international organizations (ATSC, DVB) reccomend. dmb_1
No, there different types of audio compression. I belive the compression ratio for mp3 is 11:1.
MPEG-4 compression standard was introduced in late 1998. Used for CD and streaming media distribution, as well as voice and television application. Very useful in everyday life.
