What This Actually Looks Like
The Prompt
Example Prompt
Generate captions for a 10-minute tech startup pitch video featuring speakers with Singapore and Indian accents discussing fintech solutions for Southeast Asia
Example output — your results will vary
AI produces 95% accurate captions but mishears 'DBS Bank' as 'DVD bank', 'Grabpay' as 'grab pay', and 'Gojek' as 'go check'. Technical terms like 'blockchain' and 'cryptocurrency' transcribe correctly, whilst speaker transitions and timestamps are properly formatted.
How to Edit This
Correct all company and product names using find-and-replace, verify currency mentions (SGD, INR), and add chapter markers for each pitch section. Consider adding speaker identification tags for multi-speaker clarity.
Common Mistakes
Ignoring search intent behind keywords
Stuffing keywords without natural flow
Neglecting competitor analysis in SEO
Publishing without measuring initial traction
Using generic meta descriptions
