Image and video decision
Joyflix
A competent engineer can build a limited text/image→video service, but matching JoyFlix's claimed scale, polish, proprietary models, and ecosystem features would be costly and operationally heavy.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Joyflix alternatives, with the arithmetic →
What a replacement has to do
- Enter text or upload an image → send prompt to a video-generation model → transcode/store result → play and download video
What it still won’t have
- Proprietary model improvements and any vendor-trained weights JoyFlix may run
- Polish: UI/UX, templates, and onboarding flows shown on the site
- Scale: 99.9% uptime SLA, and infrastructure for 1M+ videos/month
- Support, community, and paid features like credits system or API sales dashboard
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal self-hosted AI video generator web app using Next.js for the frontend, Node/Express for the API, Postgres for job/account metadata, AWS S3 (or compatible) + CloudFront for storage/CDN, and FFmpeg for video post-processing. Integrate a hosted text→video / image→video model endpoint (Hugging Face or Replicate) as the model provider. Core features in scope: 1) Prompt UI for text and image uploads; 2) Job enqueueing and status updates; 3) Model invocation and retrieval of raw outputs; 4) FFmpeg transcode, thumbnail generation, and S3 upload; 5) Simple job history page and download link. Out of scope: multi-tenant billing portal, credit-sales dashboard, advanced templates, enterprise SLA. Require: retriable background jobs, basic auth, error handling for model/API failures, unit tests for API endpoints, and end-to-end test for a prompt→video flow.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
