• OpenAI is building five new “Stargate” data centers with Oracle and SoftBank. “I thought I told ya that we won’t stop” vibes.

• AI replaces human subtitlers in SDH. We don’t want to see jobs replaced by AI—but in this field, it’s doing outstanding work.

• Huawei’s new superpods and superclusters put raw power on display. How powerful are they? Enough to escalate the hardware arms race.

0) Why This Matters

Streaming platforms, webinars, product demos—video is everywhere. With subtitling/dubbing now one of AI’s strongest use cases, a well-architected workflow can turn one English upload into global-ready content within hours.

1) Architecture

2) End-to-End Workflow

1. Trigger

   • Upload new video → webhook fires.

2. Transcription

   • Whisper creates English transcript with timestamps.

3. Glossary Injection

   • Pull company glossary (brand names, product terms) from Supabase.

4. Translation

   • LLM translates into target langs (Spanish, French, Japanese, Arabic).

   • Add confidence_score field per sentence.

5. Dub

   • TTS engine generates localized voice track.

   • Optionally clone speaker’s tone.

6. Subtitles

   • Sync translations back to .srt with original timestamps.

7. QC Layer

   • Any line with confidence_score <0.85 sent to human subtitler.

8. Distribution

   • Upload subtitles + audio tracks to YouTube/Vimeo.

   • Slack digest: “🌍 New video localized in 4 languages.”

QC Prompt
