Similar to MIME Type Registration for MPEG-4. If we decide to move, we need to do a PR on the Matroska public repository.įLAC: Completed prior to this initiative. Proposed Actions MatroskaįFV1: Currently using the AVI compatibility layer (similar to early version of AVC support), with active discussion about instead having a dedicated codec identifier (also similar to current version of AVC support). It is part of the IETF CELLAR Working Group. Note: Standardization of the formats themselves is excluded from this summary. This page lists a summary of what we are doing regarding the registration of these formats in standard bodies used by people and organizations working with open lossless formats. This focus is not specific to the arrangement of these formats but regards their use in other contexts as well, such as using FFV1 in the MXF format or FLAC wrapped in the QuickTime format.
Matroska, a file container with the ability to transport various media streams. advocacy and promotion of open, lossless audiovisual formats to media application developers (both proprietary and open source)įollowing with the work of the PREFORMA project we are focused on 3 open lossless formats:. open documentation efforts of open, lossless audiovisual formats for relevant communities. coordinated registration efforts for lossless formats with principal audiovisual standards organizations (IANA, IETF, ISO, SMPTE, at least). We propose accelerating the implementation of lossless audiovisual formats with the following coordinated efforts: NO PROHIBITIONS - freedom to modify and distribute the format. NO PAYWALL - freedom to read, understand, and share the format's specification. NO PATENT - freedom to read, write, and use the format. Given the opportunity for lossless compression in audiovisual media, we also propose a focus on open formats, meaning: When the preservation of quality is a requirement, lossless compression is the green option.Īlthough lossless formats have been well adopted for images, documents and other media types, the adoption of lossless formats for audiovisual recordings has been much slower. Although uncompressed digital storage is an option, uncompressed data generally contains no fixity mechanisms and generates e-waste at a much faster rate than lossless formats. 
pages) and lossless images are more ubiquitous (.png). Nowadays most digital office documents use lossless compression (.docx. In cases where digital loss is not acceptable, lossless data compression has been changing the way the world stores and transmits its data. An open effort to standardize open formats.
