-    CRF and target bitrate are now driven by `--quality`. For programmatic renders, `RenderConfig.crf` and `RenderConfig.videoBitrate` still accept overrides.
+    CRF and target bitrate default to the `--quality` preset. Use `--crf` or `--video-bitrate` for fine-grained overrides; `RenderConfig.crf` and `RenderConfig.videoBitrate` accept the same overrides programmatically.
