+-- 008 — Extended codec controls for recorders.
+--
+-- Adds video bitrate, framerate, audio codec / bitrate / channels, and
+-- container format columns to recorders so the UI can offer granular
+-- control instead of the four-options dropdown. capture-manager.js reads
+-- these via env vars and builds ffmpeg args from them.
+
+ALTER TABLE recorders
+  ADD COLUMN IF NOT EXISTS recording_video_bitrate  TEXT,
+  ADD COLUMN IF NOT EXISTS recording_framerate      TEXT,
