Media container
A media container organizes encoded tracks and the information needed to interpret them as one presentation.

A media container organizes encoded tracks and the information needed to interpret them as one presentation.
Explore →A video codec defines how pictures are represented in a compressed bitstream and reconstructed for viewing.
Explore →H.264, also called Advanced Video Coding or AVC, is a video compression format widely used in recorded and streamed media.
Explore →HEVC, also called H.265, is a video coding format designed to compress moving pictures efficiently across a range of applications.
Explore →AV1 is a video coding format developed by the Alliance for Open Media.
Explore →VP9 is a video coding format used for compressed online video.
Explore →A codec profile defines a permitted set of coding tools and constraints within a video coding family.
Explore →A codec level specifies a set of limits on the workload and resources needed to decode a bitstream.
Explore →Transcoding converts media from one encoded representation to another, usually by decoding it and then encoding new output.
Explore →Remuxing transfers already encoded media streams into a different container or packaging arrangement without decoding and re-encoding those streams.
Explore →A keyframe is commonly used to describe a coded video picture that provides an important decoding access point.
Explore →A group of pictures, usually shortened to GOP, organizes a sequence of compressed video pictures and their prediction relationships.
Explore →A presentation timestamp tells a player when a media sample should appear on the playback timeline.
Explore →Variable bitrate, or VBR, lets an encoder vary the amount of data used over time according to content complexity and its configured quality or rate objectives.
Explore →Constant bitrate, or CBR, is an encoding or transport approach designed to maintain a relatively steady data rate within its configured constraints.
Explore →MPEG transport stream, often written MPEG-TS or TS, is a container structure that carries timed audio, video and signaling in a transport-oriented packet format.
Explore →Fragmented MP4, often abbreviated fMP4, organizes media into an initialization structure and successive fragments carrying sample and timing information.
