About the formats

Extension 3g2
Alternative extension 3gp2
Category Video file formats
Developed by 3GPP (Third Generation Partnership Project for CDMA-based phones)
Mime type video/3gpp2


3G2 is a video and audio format, which is very similar to the 3GP format it is based on. It is designed for mobile devices with 3G connectivity, but 2G and 4G phones are also supported. When compared to the original 3GP format, 3G2 consumes less space and network bandwidth. It also has some other enhancements and extensions.
Extension mkv
Category Video file formats
Developed by Matroska
Mime type video/x-matroska


MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.
