OGV is a video file format that uses an open OGG container. The name of the format is also associated with this - an abbreviation for Ogg Video File. The developer of both formats is Xiph.Org. The OGV format stores video streams that use either one or several different codecs (for example, Theora). OGV files can be played on almost any media player. They are also used when displaying web pages using HTML5, however, these files (even videos) often have the .OGG extension. OGV video compression is lossy.
3GPP is a multimedia file format that is primarily intended for storing audio and video files, as well as their transfer over 3G networks. This rather sophisticated technology was developed by the consortium Third (3rd) Generation Partnership Project, whose name gave the abbreviated name of this format (3GPP). The developer created this format so that the third generation of mobile phones can use smaller files. Another task is to unify the format of audio and video files for compatibility with various mobile devices. 3GPP files can be played not only on 3G phones, but also on 2G or 4G phones.
