 This allows you to verify which recordings are in progress, troubleshoot egress issues, and confirm that recordings are being processed correctly.

-## Tuning recording encoding
-
-By default, LiveKit Egress records with the built-in `H264_720P_30` preset: 1280×720 at 30 fps, 3000 kbps H.264 MAIN video and 128 kbps AAC audio. For a one-hour meeting this produces a file of roughly **1.4 GB**, which is often heavier than necessary for talking-head content and screen sharing.
-
-The `RECORDING_ENCODING_*` settings let operators override this preset without modifying the source. Values are passed straight through LiveKit's `EncodingOptions.advanced` to the GStreamer pipeline (`x264enc` for video, `faac` for audio), so there are no hidden conversions — what you set is what the encoder receives.
-
-### How values map to GStreamer
-
-| Setting                               | GStreamer element | Property                           |
-| ------------------------------------- | ----------------- | ---------------------------------- |
-| `RECORDING_ENCODING_WIDTH/HEIGHT`     | capsfilter        | `video/x-raw,width=W,height=H`     |
-| `RECORDING_ENCODING_FRAMERATE`        | capsfilter        | `framerate=F/1`                    |
-| `RECORDING_ENCODING_VIDEO_BITRATE_KBPS` | `x264enc`       | `bitrate=kbps` (kilobits)          |
-| `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S` | `x264enc`     | `key-int-max = interval × fps`     |
-| `RECORDING_ENCODING_AUDIO_BITRATE_KBPS` | `faac`          | `bitrate = kbps × 1000` (bits)     |
-
-The H.264 profile is fixed to MAIN and the x264 `speed-preset` to `veryfast` by LiveKit (real-time constraint) — lowering the framerate is therefore the main lever to save CPU, while lowering the bitrate is the main lever to shrink the output file.
-
-### Reference profiles
-
-Rough 30-minute file-size estimates assume video + audio bitrate multiplied by duration. Actual sizes vary with content (static talking heads compress better than heavy screen motion). Egress CPU figures are indicative, measured on a single Ryzen laptop core saturated by the default preset (= 100 %); scaling is roughly linear with `framerate × bitrate` but the absolute numbers depend on the host hardware.
-
-| Profile                | Resolution | FPS | Video (kbps) | Audio (kbps) | Keyframe (s) | ~ size / 30 min | Egress CPU (vs. default) | Suitable for                                        |

-### Caveats
-
- **Screen-share readability — think bits/frame, not bitrate**: at 720p, text legibility starts to break down below ~40 kbits/frame (= `bitrate ÷ framerate`). The recommended preset (600 kbps × 15 fps) sits at exactly that threshold, comfortable for talking heads with occasional slide sharing. The same 600 kbps at 30 fps would only deliver 20 kbits/frame and visibly blur dense slides — which is why **lowering framerate is a more screen-share-friendly lever than lowering bitrate**. For deck-heavy or IDE-share meetings, prefer the **Slide-heavy** profile (900 kbps × 15 fps ≈ 60 kbits/frame).
- **Motion handling**: the `veryfast` x264 preset is set by LiveKit and cannot be overridden here. Low-bitrate settings will therefore show more artefacts on fast motion than an offline re-encode with a slower preset would. This is the other reason FPS reduction is the safer tuning lever for meeting recordings.
- **Audio**: AAC at 64 kbps stereo is transparent for voice but starts to compress music noticeably. Keep 128 kbps if you expect music playback in meetings.
- **Codec choice**: H.264 MAIN is hardcoded on purpose. Switching to HEVC or VP9 would increase egress CPU cost 2×–5×, defeating the goal of this tuning.
