lib.video-gen

@lssm-tech/lib.video-gen

AI-powered video generation with Remotion: compositions, rendering, and design integration.

What It Provides

• Layer: lib.
• Consumers: bundles, video-studio app.
• src/docs/ contains docblocks and documentation-facing exports.
• Related ContractSpec packages include @lssm-tech/lib.ai-providers, @lssm-tech/lib.content-gen, @lssm-tech/lib.contracts-integrations, @lssm-tech/lib.contracts-spec, @lssm-tech/lib.design-system, @lssm-tech/lib.image-gen, ...
• src/docs/ contains docblocks and documentation-facing exports.

Installation

npm install @lssm-tech/lib.video-gen

or

bun add @lssm-tech/lib.video-gen

Usage

Import the root entrypoint from @lssm-tech/lib.video-gen, or choose a documented subpath when you only need one part of the package surface.

Architecture

• src/compositions is part of the package's public or composition surface.
• src/design is part of the package's public or composition surface.
• src/docs/ contains docblocks and documentation-facing exports.
• src/generators is part of the package's public or composition surface.
• src/i18n is part of the package's public or composition surface.
• src/index.ts is the root public barrel and package entrypoint.
• src/player is part of the package's public or composition surface.
• src/types.ts is shared public type definitions.

Public Entry Points

• Export . resolves through ./src/index.ts.
• Export ./compositions resolves through ./src/compositions/index.ts.
• Export ./compositions/api-overview resolves through ./src/compositions/api-overview.tsx.
• Export ./compositions/companyos/timeline — computeOwnersFirstArticleTimeline, OwnersFirstArticleTimeline, COMPANYOS_FILM_FPS, NarrationMeasure. The timeline is audio-led: beat durations (question circled on paper, match cut, decide line, silent decision, brand close) are derived from measured narration durations, not hardcoded frame counts.
• Export ./compositions/primitives resolves through ./src/compositions/primitives/index.ts.
• Export ./compositions/primitives/animated-text resolves through ./src/compositions/primitives/animated-text.tsx.
• Export ./compositions/primitives/brand-frame resolves through ./src/compositions/primitives/brand-frame.tsx.
• Export ./compositions/primitives/code-block resolves through ./src/compositions/primitives/code-block.tsx.
• Export ./compositions/primitives/progress-bar resolves through ./src/compositions/primitives/progress-bar.tsx.
• Export ./compositions/primitives/terminal resolves through ./src/compositions/primitives/terminal.tsx.
• Export ./compositions/primitives/transition resolves through ./src/compositions/primitives/transition.tsx.
• Export ./design/companyos-campaign — Remotion-local token definitions (companyOsCampaignFilmTokens) mirroring the companyos.design.room-for-work campaign palette. Remotion frames cannot read CSS variables from the host app, so semantic values are reproduced here as a token object.
• Export ./i18n/companyos-film — en/fr/es narration keys, story scripts, and locale helpers for the CompanyOS film (see below).
• The package publishes 42 total export subpaths; keep docs aligned with package.json.

CompanyOS film compositions

OwnersFirstArticle (in src/compositions/companyos/) is the first Remotion composition for the "Room for the real work" campaign. It targets an 8–12 s runtime and plays four beats: a question circled on the paper proposal (narrated), a match cut to the same proposal inside CompanyOS (narrated), a silent human decision, and the brand close. Product frames are labelled on screen as an illustrative reconstruction.

Props (OwnersFirstArticleProps):

• locale: one of 'en' | 'fr' | 'es'
• timeline: a pre-computed OwnersFirstArticleTimeline from computeOwnersFirstArticleTimeline
• audioSrc (optional): path to the final mix WAV under the studio public/ folder; omit for silent previews

The timeline must be computed from measured narration durations (NarrationMeasure.durationSec), not estimated. Durations come from the narration manifest written by the companyos:narrate script in @lssm-tech/app.video-studio.

CompanyOS film i18n (./i18n/companyos-film)

Provides localized copy and story scripts for the owners-first-article film.

• getCompanyOsFilmMessages(locale) — returns narration key/value messages for the given CompanyOsFilmLocale. Throws for unsupported locales; never falls back silently to English.
• getCompanyOsStoryScripts(locale) — returns CompanyOsStoryScripts (array of CompanyOsStoryBeat per story id).
• COMPANYOS_FILM_LOCALES — ['en', 'fr', 'es'] as const.
• companyOsFilmTranslations — translation specs registered with the shared runtime for all supported locales; keys are under video-gen.companyos-film.
• COMPANYOS_FILM_KEYS, COMPANYOS_STORY_IDS, CompanyOsFilmMessageKey, CompanyOsFilmMessages, CompanyOsStoryId, CompanyOsStoryBeat — exported types and key registries.

Translation content carries stability: 'experimental' and description: 'CompanyOS campaign film frames and narration (draft for native review)'. Native-speaker review is required before production narration is approved.

Recent Updates

• Replace eslint+prettier by biomejs to optimize speed.
• Resolve lint, build, and type errors across nine packages.
• Add first-class transport, auth, versioning, and BYOK support across all integrations.
• Add AI provider ranking system with ranking-driven model selection.
• Resolve lint/test regressions after voice capability updates.
• Add @lssm-tech/lib.voice package for TTS, STT, and conversational voice.

Notes

• Remotion composition API is version-sensitive — pin and test upgrades carefully.
• Renderer interface is the adapter boundary — do not leak Remotion internals.
• Depends on voice, content-gen, image-gen, design-system — coordinate cross-lib changes.
