It is ideal for preserving original audio quality, making it especially useful for tasks like ripping audio from DVDs. OGG provides a better balance of file size and audio fidelity compared to MP3.

Like AVI, Ogm supports various codecs for audio and video compression, including popular ones like DivX/XviD. It's designed to offer more flexibility and functionality compared to traditional formats like AVI.

OGG (short for "Ogg Vorbis") is a free, open-source container format used for storing multimedia files, primarily audio, but also video and metadata.
