Upstream documentation tells you what a parameter means; tutorials teach a workflow. Read the documentation for the release you actually run, because a master or latest page can describe different defaults from your build.

Specifications and upstream tool documentation

Reference	Useful for
ITU-T H.273	Color-signaling code points. The in-force edition is 07/24.
FFmpeg manuals	Stream selection, encoders, filters, formats, and ffprobe. Your build’s -h output lists what it actually includes.
x265 documentation	Native x265 CLI/API controls and release notes. FFmpeg’s wrapper is a separate interface.
VapourSynth documentation	Core and Python APIs. External plugin dependencies are separate.
Xiph.Org documentation	Opus, Vorbis, FLAC, Theora and Ogg project pages.

Each tool page on this wiki ends with a full option table; Reading option tables lists them.

Community workflows

• Fansubbing Guide covers fansubbing, filtering, resampling and encoding. Its introduction says it is still under construction, so check individual examples and dependency versions.
• SilentAperture’s Advanced Encoding Guide covers source preparation, filtering and test encodes for high-quality encodes.
• lvsfunc documentation describes VapourSynth helper functions. The project warns that its public API may change at any time, so pin a package version for reproducible scripts.
• Kokomins’ anime/x265 article walks through x265’s psychovisual options (psy-rd, psy-rdoq, AQ, deblocking, no-sao) for anime. It dates from 2019, so check its values against current x265 defaults.

The old third-party x264 settings summary still explains many options well but is not maintained; use the x264 page and x264 --fullhelp for current values.
