FAQ

Questions & Answers

MP4

MPEG-4 file format

MP4(short for MPEG-4 Part 14) is a file format based on ISO/IEC 14496-12:2004 that is based on QuickTime File Format but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features. It is mostly used to store video and audio but can also be used to store subtitles and still images. MP4 files are stored with the .mp4 extension. MP4 is an international audio-visual coding standard. Similar to most modern container formats, MP4 supports streaming over the internet. Due to the high compression used in MP4, the resultant files are smaller in size with almost all the original quality retained.

MKV

Matroska Video file format

MKV (Matroska Video) is a multimedia container similar to MOV and AVI format but it supports more than one audio and subtitle track in the same file. An MKV file is the Matroska multimedia container format used for video. MKV is based on Extensible Binary Meta Language and it supports several video and audio compression formats. The major difference between MKV and other video formats is that MKV is a container and not a codec. MKV files are saved with the .mkv file extension. MKV can incorporate audio, video, and subtitles in a single file even if those elements use different types of encoding. For example, you could have an MKV file that contains H.264 video and MP3 or AAC for audio. MKV also supports descriptions, ratings, cover art, and even chapter points.
