Audio and podcasting decision
Translate-Dub.com
A capable technical user can build a useful single-user replacement in about a week using off-the-shelf ASR/translation/TTS APIs and FFmpeg; the vendor's main advantages are product polish and voice models, not structural moats.

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 Translate-Dub.com alternatives, with the arithmetic →
What a replacement has to do
- Upload a video → transcribe audio → translate transcript → synthesize translated speech → render captions and mux audio into output → generate watermarked preview → accept payment and deliver final file.
What it still won’t have
- Proprietary voice models or any custom-trained voices the vendor may use
- Polished UI/UX, caption style presets and voice presets
- Optimizations for scale, latency, and multi-format social outputs
- Commercial testing and edge-case handling for many languages and accents
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a single-tenant web service (React frontend, Node.js/Express backend, Postgres for metadata, S3-compatible storage, FFmpeg for muxing) that: 1) accepts MP4/MOV/WebM uploads and stores originals; 2) calls a speech-to-text API (or local Whisper worker) to produce a timed transcript; 3) calls a translation API to produce translated text and generate SRT/VTT timings; 4) calls a TTS API to synthesize translated audio and aligns it to the video timeline; 5) renders styled burned captions via FFmpeg and produces a short, watermarked preview and a full unlocked download after payment; 6) integrates Stripe for one-time payments and emails delivery links after successful checkout. Out of scope: training custom voice models, advanced lip-sync beyond time alignment, multi-tenant billing dashboard. Include error handling, retries for external APIs, background job processing (e.g., Bull/Redis), unit and integration tests, and Docker-based deployment scripts and simple monitoring (health check, basic logs).

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.
