✅ Option A — Short videos (under 30 min):
Upload to YouTube as unlisted → YouTube auto-generates captions → copy the transcript

✅ Option B — Any length, more accurate:
Go to https://huggingface.co/spaces/openai/whisper (OpenAI's free Whisper demo) or use AssemblyAI free tier
Upload your audio file → get accurate transcript in minutes

✅ Option C — Already have a script:
Skip this step entirely — paste your script directly into Step 2

✅ Translation prompt for Claude:
"Translate this script from Spanish to English. Keep the same conversational tone, sentence length, and energy. This will be used for a voice dubbing of a YouTube video — it needs to sound natural when spoken aloud, not like a formal translation. Script: [paste your script]"

Pro tip: Ask Claude to also add "[PAUSE]" markers where you naturally pause in the original — this helps sync the dubbed audio later.

1. Go to elevenlabs.io → Sign up free
2. Click "Voices" → "Add Voice" → "Voice Clone"
3. Record 60 seconds of yourself speaking clearly (any content)
4. Name it "My English Voice"
5. Go to "Text to Speech"
6. Select your cloned voice

✅ CapCut dubbing steps:
1. Open CapCut → New Project → Import your video
2. Select the video clip → click "Audio" → set volume to 0 (mute original)
3. Click "Audio" in toolbar → "Import" → upload your ElevenLabs MP3
4. Drag the dubbed audio to align with the video start
5. Use the waveform to manually sync key moments

Sync tip: Find 3 clear moments where your mouth movement matches a word — align those first, then the rest follows naturally.
