v1 onboarding demo, Option B (post-compositing): scenario and shot-list

The story (one save, and it's on your website)

A person gets a trip2g-backed vault, opens it in Obsidian, writes their first page, hits save — and the page is live on their own website a second later. No terminal on screen: the sync is the product's own Obsidian plugin (autoSyncOnSave), the browser shows the page on the real local instance.

Screen setup (all real, Xvfb :98, 2560×1440, no WM)

Window	What it is	Honesty note
Left (1260×1010 @ 40,60)	Obsidian 1.12.7 (real AppImage, isolated XDG_CONFIG_HOME), vault served by memcli instance demoB; trip2g sync plugin v0.6.1 enabled (community plugins on, autoSyncOnSave: true)	the push on screen is the plugin's own debounced auto-sync (2.5 s after the last edit); the toast is the plugin's real Notice
Right (1120×1010 @ 1360,60)	Chromium on http://localhost:24281 — the memcli-booted trip2g server (docker, trip2g-memory-demoB) rendering the vault	logged in once as the owner via a one-time ?hat= URL; page load and URL typing are real

No window manager: Option B captures the full screen once and crops each window in post, so windows just sit at fixed rects on a black root. The pointer is parked outside both windows — takes are keyboard-driven, so the crops never show a stray cursor (and there are no janky pointer teleports on camera).

Narration (ElevenLabs eleven_multilingual_v2, voice tvApEij8Hu2VscOrlzzV, 24.71 s)

A plain Obsidian vault on the left. On the right — my own website, served by self-hosted trip2g. I create my first page: a title, and one line of text. I hit save. The sync plugin pushes it to the server automatically. Now open the page — and it's live. Write in Obsidian, save, and it's on your website. Try it yourself — the repo is trip2g on GitHub. And if you like it, star it.

Beat sheet (times = seconds on the VO clock; the audio is the clock)

t (s)	VO says	On screen
0.0–6.6	"A plain Obsidian vault… my own website, served by self-hosted trip2g."	static two-window scene, Obsidian focused (empty New tab), browser on the vault Index
6.5	"I create my first page:"	ctrl+n (then a generous 1.4 s pause — a cold Obsidian drops the first keystrokes of the inline title otherwise)
7.9–9.0	"a title"	type My first live page, Return
9.3–11.3	"and one line of text"	type Hello world! This page went from Obsidian to my own website with one save.
11.6	"I hit save."	ctrl+s
~13.8	"…pushes it to the server automatically."	the plugin's debounce fires: "Pushed 1 files to server" toast
13.9–15.5	"Now open the page"	focus browser, ctrl+l, type localhost:24281/my_first_live_page, Return
~15.9	"and it's live."	the page renders: same title, same line, real server
15.6–21	"Write in Obsidian, save, and it's on your website."	hold on the two windows
21.3→	"Try it yourself — the repo is trip2g on GitHub…"	end card fades in (0.7 s): trip2g / github.com/trip2g/trip2g / "Try it yourself — ⭐ star it on GitHub"
24.7–26.5	(silence)	end card holds, cut

Word timings come from the ElevenLabs with-timestamps alignment (optB/vo-align.json); record.mjs schedules beats against wall-clock t0, and composite.sh computes the exact audio offset from the recording's ffprobe start_time — same deterministic sync approach as the first hero cut.

Option B post pipeline (composite.sh)

1. One 2560×1440 x11grab take (raw.mkv, crf 16) of the bare windows on the black root.
2. ImageMagick builds a static plate: fal.ai wallpaper (decorative only) + per-window soft shadow (blurred rounded rect) + white rounded frame with a grey 44 px title bar and red/yellow/green traffic lights (SrcAtop keeps the strip inside the rounding).
3. ffmpeg crops each window from the take, rounds its bottom corners (alphamerge), and overlays both crops onto the plate — product pixels untouched, only re-framed.
4. End card (endcard.html → headless-Chromium PNG, same wallpaper) fades in at VO 21.3 s.
5. VO muxed with the computed offset; master libx264 crf 17 veryslow, 2560×1440.
6. Silent README loop GIF: VO 5.4→19.0 s (create → save → push toast → live page), 14 fps, 1080 px, palette dither — 0.5 MB (≤5 MB budget).

Cuts

• Narrated MP4 (landing/social): docs/demo-video/v1-optB-post.mp4 — 2560×1440, ~29 s, 1.9 MB, VO + CTA end card.
• README loop GIF (silent, no CTA): docs/demo-video/v1-optB-post.gif — 13.6 s core loop, 1080 px, 0.5 MB.

One-time interactions on a fresh rig: Obsidian's vault-trust dialog (Trust author and enable plugins — the plugin must run) and a history clear in Chromium after the ?hat= login (keep cookies) so the one-time token never shows up in omnibox suggestions on camera.

Known blemishes (accepted)

• Obsidian shows its Linux window controls (−□×) inside the frame next to the added macOS traffic lights — honest capture of the real app, kept.
• The plugin's red "sync warnings" ribbon badge is visible in Obsidian's status bar — real UI, kept.
• The browser is logged in as the instance owner; the page itself is also publicly reachable (curl 200 without cookies).
• A cold-started Obsidian (<1 min uptime) drops the first keystrokes after ctrl+n — cost takes 1 and 3; warm the app before recording.
