FAQ

Where should I start?

Follow the first FFmpeg encode for a complete beginner workflow, then choose a codec and encoder for your playback and editing targets. Codec pages describe formats; encoder pages describe the programs that write them. A codec name alone does not tell you the profile, chroma format, HDR support or browser compatibility.

Why Encode Wiki?

Multimedia compression has no easy entry point: Wikipedia covers individual topics, and the rest of the knowledge is scattered across forums, Discord servers and old guides. Encode Wiki puts codec explanations, encoder settings, practical guides and dated experiments in one place. It includes material migrated from the community Codec Wiki, with provenance and license kept; in older articles, “Codec Wiki” means that original project.

How old is too old for a benchmark?

Encoders change quickly, so a comparison is only as current as the versions it tested. Check an article’s encoder versions, presets, metric implementation and hardware before reusing its conclusions, and expect old presets and fork-specific flags to behave differently or not exist in current releases. Comparing encoding quality explains what a fair comparison needs.

Where are more resources?

The resource page lists upstream specifications and tool documentation first, then community tutorials. The tutorials explain workflows well, but several were written for older plugin interfaces and encoder versions.

How can I contribute?

Open a merge request against master in the GitLab project. Cite primary sources for technical claims and say which tool versions you used for commands. The repository’s CONTRIBUTING.md covers the details; the contribution guide summarizes it and explains what changed from the old Codec Wiki process.
