Sam is launching a new open-source tool and needs a short video for his README, X post, and product page. He opens DevClip, pastes the README, and selects a launch demo format. In minutes, the app turns his text into a storyboard, narration, captions, and a polished export he can share the same day.

Instead of spending an evening in a complicated video editor, Sam makes a few quick edits to the script and swaps one scene to highlight the best feature. The final MP4 is branded, captioned, and ready for social channels. For Sam, the value is speed and professionalism; for the business, it means a repeatable creation workflow that drives frequent exports and paid upgrades.

Technical Needs

Frontend in Next.js with React and TypeScript.
Backend API in Node.js with NestJS or Fastify.
Job queue for rendering workflows using BullMQ and Redis.
Media processing pipeline using FFmpeg for compositing and transcoding.
PostgreSQL for core application data and job metadata.
Object storage on AWS S3 or Cloudflare R2 for uploads and rendered assets.
Observability with Sentry, OpenTelemetry, and a log aggregation service like Datadog or Grafana Loki.

Integration Points

Google OAuth and email auth via Auth.js or Clerk.
OpenAI or similar LLM API for script and scene generation.
ElevenLabs or OpenAI TTS for voiceover generation.
AWS S3 or Cloudflare R2 for asset storage and downloads.
Stripe for subscriptions and usage-based billing.

Data Storage & Privacy

Store only user-provided content required for generation and editing.
Encrypt sensitive data at rest and use TLS in transit.
Provide data deletion and export workflows for GDPR and CCPA requests.
Separate workspace assets from billing and auth data with strict access controls.
Define retention policies for raw uploads, generated audio, and rendered videos, with automatic cleanup of abandoned drafts.

Scalability & Performance

Use asynchronous rendering so the UI remains responsive during long jobs.
Cache generated storyboard outputs to avoid regenerating unchanged inputs.
Scale render workers horizontally based on queue depth.
Use CDN delivery for previews and final exports to reduce download latency.

Potential Challenges

Accurate technical narration can be wrong or oversimplified; mitigate with user review, highlighted uncertain phrases, and manual edits.
Media rendering can be slow under load; mitigate with job queues, worker autoscaling, and estimated completion times.
Copyright and asset ownership may be unclear for imported images or logos; mitigate with upload warnings and asset provenance notices.
Voice output may sound unnatural for developer terms; mitigate with pronunciation overrides and voice sampling.
Large uploads could increase storage and bandwidth cost; mitigate with file limits, compression, and lifecycle cleanup.

Build a web app called DevClip for software developers to turn prompts, markdown, README files, and docs URLs into short polished videos.

Core features:
1. Auth with email and Google.
2. New project flow: choose input type, paste text or import markdown/URL, choose video goal (launch demo, tutorial, product update), aspect ratio (16:9, 1:1, 9:16), and voice.
3. AI storyboard generation: split content into scenes with narration, visual suggestions, and estimated duration.
4. Editable scene list: reorder scenes, edit narration text, adjust durations, regenerate a single scene.
5. Branding: upload logo, pick brand colors, choose font, set default CTA.
6. Export pipeline: render MP4, generate SRT/VTT captions, show progress and retries, provide download and share link.
7. Project dashboard with drafts, exports, and version history.

Data model:
Users, Workspaces, Projects, Inputs, Scenes, Assets, BrandKits, Renders, Shares, BillingSubcriptions, AnalyticsEvents.
Each Project has title, sourceType, sourceContent, selectedFormat, voiceId, brandKitId, status, createdAt, updatedAt.
Each Scene has projectId, orderIndex, title, narration, visualType, durationSeconds, captionText, status.
Each Render has projectId, resolution, aspectRatio, status, progress, outputUrl, subtitleUrl, errorMessage.

Tech stack:
Next.js 14 or 15, TypeScript, Tailwind CSS, shadcn/ui, PostgreSQL with Prisma, Redis with BullMQ for render jobs, S3 or R2 for assets, FFmpeg for media processing, Auth.js or Clerk for auth, Stripe for billing, Sentry for errors, OpenAI or similar LLM API for generation, ElevenLabs or OpenAI TTS for voiceover.

Primary screens:
Landing page, signup/login, dashboard, new project wizard, project editor with storyboard and preview, branding settings, export modal/progress screen, share page, billing page.

Implementation requirements:
Make the UI clean, fast, and accessible. Use autosave, optimistic updates, and clear empty states. Build responsive layouts for desktop first, but make the editor usable on tablet. Include seeded demo data and a few example templates. Create API routes or server actions for project creation, storyboard generation, scene updates, render jobs, and share links. Use background workers for rendering and return job status via polling or realtime updates.

Start with a working MVP that can create a project, generate scenes, edit them, and export a mock or placeholder render if full media compositing is not yet ready.
