Universal Subtitle Format (USF) is a CoreCodec project to create a clean, documented, powerful and easy to use subtitle file format. It is based on XML for flexibility, unicode support, hierarchical system, and ease of administration. USF subtitles are usually used in Matroska containers. The format has come under criticism, especially from the fansub community, because compared to the format it aims to replace, Advanced Substation Alpha (which is based on comma-separated values), it is more verbose and far harder for software to read, write and manipulate. It is also much harder to edit "by hand" in text editors such as Notepad. For these reasons, as well as the lack of a generic cross-platform parsing/rasterizing library and mature editing programs that natively support it, the format has not gained wide acceptance. No known media player software implements more than basic support for this format. VSFilter, and VLC media player (starting with the 0.9.0 release) can extract the subtitle text, timing information and very restricted formatting. Documentation for the format is now hosted by the Danish subtitling software company Titlevision (here ). == Example == Below is the example USF file as presented in the v1.1 specification:〔(USF Specification v1.1 )〕 The Core Media Player small sample, let's sing a song.
