- Footage can store custom proxy parameters (width/height/crf/preset/ extension/audio) that override the global settings; they are serialized with the project and used by every generation entry point via Footage::GetEffectiveProxyParams() - Proxies now include the source audio streams (AAC) unless disabled; the proxy filename records the audio flag and offline audio rendering decodes from the proxy when present - ProxyTask resolves ffmpeg from the new FFmpegPath config key first, then PATH, then common install locations (e.g. Homebrew on macOS), instead of relying on PATH only; the error message points at the preferences when no executable is found - ProxyTask::BuildArguments() is extracted for testability - Add ProxyIncludeAudio and FFmpegPath config defaults - Add regression tests for the filename audio marker, config-backed params, ffmpeg resolution, argument building, and custom-param persistence
