screen-recording
Professional screen and camera recording on codeonym's Arch workstation (GNOME 50 Wayland, AMD Vega VAAPI) with OBS Studio 32 and its plugin pack (advanced masks, composite blur, shaderfilter, source clone/record, freeze, 3D effect, stroke/glow/shadow, background removal, PipeWire app audio, Wayland hotkeys, advanced scene switcher, move transition), showmethekey for keystroke overlays, OpenScreen for Screen Studio–style auto-zoom demos, and GNOME cursor tweaks. Use when the user wants to record a tutorial, demo, course, talk or stream, set up or configure OBS scenes/profiles/filters, needs zoom-on-click or cursor highlighting, keystroke display, or wants to clean up a finished recording.

# Screen recording (OBS · showmethekey · OpenScreen)
## Toolkit on this machine
| Tool | Use it for | Launch |
|---|---|---|
| **OBS Studio 32** | Scenes (screen, cam, screen+cam), filters, recording, streaming | `obs` |
| OBS plugins | see `references/obs-plugins.md` — what each does and how to use it | inside OBS |
| **showmethekey** | On-screen keystroke overlay (Wayland-compatible) — capture its window in OBS | `showmethekey-gtk` |
| **OpenScreen** (AUR `openscreen`) | Auto-zoom on clicks, smooth cursor, backgrounds — polished product demos | `openscreen` |
| **GNOME cursor settings** | Bigger cursor + Ctrl ripple ("locate pointer") | `scripts/presenter-mode.sh` |
| **Kdenlive / ffmpeg** | Editing and delivery | `video-editing` skill |
## Wayland reality check (important)
- OBS captures the screen through **PipeWire + the GNOME portal**: *Screen Capture (PipeWire)* source; GNOME asks which screen/window on first use.
- **Live zoom-follow-mouse inside OBS does not work on Wayland** (plugins/scripts need X11 cursor coordinates; GNOME 50 has no X11 session). Options:
1. **OpenScreen** — record, then it auto-generates zooms on clicks (Screen Studio style). Best for product demos.
2. **Manual zooms in OBS** with *Move Transition* (hotkey → animate a zoomed crop of the screen source) — best for live/tutorial flow.
3. **Zooms in post** in Kdenlive with keyframed *Transform* (see `video-editing` → `kdenlive-workflow.md`).
- Global hotkeys need the **obs-wayland-hotkeys** plugin (uses the GlobalShortcuts portal), otherwise they only work while OBS is focused.
## Scripts
| Script | What it does |
|---|---|
| `check.sh` | OBS + every plugin, PipeWire/portal stack, VAAPI encode, showmethekey/OpenScreen, cursor settings, existing OBS profiles |
| `presenter-mode.sh on [size] \| off \| status` | Bigger cursor + Ctrl ripple for recording; `off` restores your previous settings |
| `finish-recording.sh <rec.mkv> [--trim-start S] [--trim-end S] [--target -14] [--denoise]` | Lossless remux to MP4, trim, loudness normalize, and a small review copy |
## Guides
- `references/obs-setup.md` — the recommended profile (VAAPI, CQP, MKV + auto-remux), scene collection layout, mic filter chain, hotkeys.
- `references/obs-plugins.md` — each installed plugin: what it's for and a concrete recipe.
- `references/recording-workflow.md` — pre-flight checklist, recording technique, and post-production pipeline.
## Rules of thumb
1. Record **MKV** (crash-safe) with *Automatically remux to MP4* on.
2. Encoder: **FFmpeg VAAPI H.264**, CQP 18–20 — the CPU stays free for the apps you demo.
3. Canvas 1920×1080; scale your apps so text is readable at 1080p (VS Code font ≥ 16, browser zoom 125 %).
4. Separate tracks: mic on track 1, desktop audio on track 2 (Advanced audio properties) — fix balance in the edit.
5. Presenter mode on, notifications off (*GNOME → Do Not Disturb*), clean desktop.
