Let’s first begin by talking about codecs, which deal with compressing your fileĬodecs (are for compression) – or COder/DECoder This file allows the client or device to automatically select the best quality stream at any time, to prevent playback buffering regardless of bandwidth or CPU power.

Another feature for the HLS format is the M3U8 file descriptor. This format uses HTTP - the universal language protocol for the internet, and allows for reduced infrastructure costs, greater reach, and simple HTML5 player implementation. HLS or HTTP Live Streaming use adaptive bitrate streaming techniques to enable high quality streaming with small HTTP-based file segments. One of the most popular formats that supports ABR is HLS. There are other file formats that support adaptive bitrate (ABR), which adapts the quality of your stream to match the internet speed of your player.

MP4 files are played at a constant bit rate (CBR), meaning the quality of your video stream remains at the same bitrate no matter the variance in your internet bandwidth. This means H.265 4K content that is easier to stream and at a higher quality than 4K content compressed using H.264. H.265 compresses videos far more efficiently (hence the “high efficiency”) when compared to H.264.

If AVC or H.264 was the codec of 1080p content, then HEVC and H.265 is the codec for the 4K era. HEVC, short for High Efficiency Video Coding, or H.265 is slowly becoming universal thanks to the spread of 4K content. The H.264 codec compression technology is present everywhere, with decoders available for pretty much every platform and mobile device. H.264 is the most widely used video codec. Both mobile and desktop devices can playback MP4 video files, so it makes sense that it would be used by most content producers. MP4 is widely used because of how universal it is across a range of devices. MP4, while MPEG 4 Audio has the file extension.

Don’t confuse MPEG 4 and MPEG 4 Audio MPEG 4 has the file extension. MP4 is a multimedia container for video, audio, and data, including things like subtitles and still images. The most popular video format is MP4, also known as MPEG 4. Formats are developed to improve image quality, decrease file sizes, allow for universal playback on a variety of devices, and provide special features such as subtitles. File formats are used so that a variety of devices, platforms, and players can process and playback any number of codecs. Metadata is any data outside of audio and sound, including bitrate, resolution, subtitles, device type, and date of creation.įormats are the entire set of storage rules that package a video file’s container, codecs, and metadata. A file’s video stream includes the data necessary for motion video playback, while the audio stream includes any data related to sound. All the data put together, both streams and the metadata, is read by a video player to stream video content for playback. Video formats are much more than that and include a whole package of files, including a files video stream, the audio stream, and any metadata included with the file. Video formats are often called as a file’s extension, for example the. Video formats, for the purposes of this article can be placed in one or more of the following categories: acquisition, editing, and delivery. Each compression scheme can be implemented in different ways which creates different codecs for the same compression scheme.

Common compression schemes include H.264, MPEG4 part 2, ProRes, DNxHD, and so on.Ī codec (encoder/decoder) is a piece of hardware or software that interprets an audio or video signal and compresses it. Inside of each audio and video track, the information is represented in the language of the compression scheme. Common container formats include MOV, MXF, and AVI.Ĭompression Scheme – The Language of the Book The multimedia container is like the bookshelf in that it can hold many tracks of audio and video just like a bookshelf can hold many books. Think of a video file as a bookshelf filled with books. To understand the difference between a container, a compression scheme, and a codec, first we need to break down the parts of a video file.
