Screenshot of Windows Media Encoder 9 Series, displaying new encoding options for Windows Media Audio 10 Professional. Windows Media Audio Professional (WMA Pro) is an improved lossy codec closely related to WMA standards. It retains most of the same general coding features, but also features improved entropy coding and quantization strategies ...
Lossy formats Audio compression format Algorithm Sample rate Bit rate Latency CBR VBR Stereo Multichannel; AAC: MDCT, Hybrid Subband (AAC-HE) : 8–192 kHz, also: 7.35 kHz, but used rarely.
The video can be downloaded by selecting the format code from the list or typing the format manually: youtube-dl -f <format/code> <url> Best quality video can be downloaded with -f best option. Also, the quality of audio and video streams can be specified separately and merged with the + operator.
Vorbis is a free and open-source software project headed by the Xiph.Org Foundation. The project produces an audio coding format and software reference encoder/decoder ( codec) for lossy audio compression, libvorbis. [10] Vorbis is most commonly used in conjunction with the Ogg container format [11] and it is therefore often referred to as Ogg ...

Some are combinations of common container formats and audio and video coding profiles, such as AVCHD and DivX formats. Although sometimes compared to DivX products, Xvid is neither a container format nor a video format, it is a software library that encodes video using specific coding profiles of the common MPEG-4 ASP video format. Those types ...
Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats . The compression may employ lossy data compression, so that quality-measurement issues become important.
Video file format. A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g ...
