3GP Compressor

You may need to compress 3GP video for many different reasons - to save space in the device's memory or to transfer a file over the Internet. In any case, you need a good compressor that will do its job at the highest level. Modern video compression algorithms differ from image compression algorithms with which you may be familiar. The extra dimension and time means that various mathematical and logical methods are applied to the video file to reduce the size while maintaining the video quality. Video compression algorithms look for spatial and temporal redundancy. By encoding redundant data a minimum number of times, the file size can be reduced. Imagine, for example, one minute as the character's face slowly changes its facial expression. It doesn't make sense to encode a background image for each frame: instead, you can encode it once and then refer to it until you know the video is changing. This inter-prediction coding is responsible for artifacts that interfere with the compression of digital video: parts of the old image move with the wrong action because something in the coding has become useless.

The 3GP file contains multimedia data in an audio and video container format developed by the 3rd Generation Partnership Project (3GPP) consortium for mobile telephony. It is used to transfer audio and video over the Internet, as well as save videos captured on a mobile device. The finished video clips in 3GP have a small size compared to similar videos in other formats, however, this is justified by a rather low quality, for example, often many frames are presented in the form of colored squares. This format is used to play videos, most often on mobile phones. Its peculiarity lies in the size of the files being played - it is much smaller than, for example, avi. The disadvantage of 3GP is quality, but it is ideal for playing on mobile phones. A 3gp file is a small footage created for playback on portable devices (phones, smartphones, tablets, etc.).
