Why this works for LinkedIn
LinkedIn videos need professional, brand-safe captions. Corporate-clean-pill or interview-clean-bottom are the only styles that look at home on a feed dominated by business posts.
Why Whisper handles Spanish well
BurnSub uses OpenAI's Whisper-Turbo (Whisper code: es),
which has been trained on hundreds of thousands of hours of Spanish speech.
Accuracy on clear-audio Spanish content is typically 92–97%.

Frequently asked
Is auto-caption accurate for Spanish?
Whisper-Turbo's accuracy on Spanish audio is typically 92–97% for clear speech. Background noise, heavy accents, and slang reduce accuracy. Every caption line is editable before burning, so you can fix anything Whisper missed.
Does the LinkedIn algorithm reward burned captions?
Burned captions are read directly by viewers (the words appear on screen) — no AI-detection step required. LinkedIn typically rewards videos with on-screen text because watch-time goes up. Burned subs typically out-perform soft subs on sound-off feeds.
Can I use Spanish subs on a video that's spoken in another language?
Yes — generate the original-language transcript first, then use a translation tool to render it in Spanish, paste the translated SRT back in BurnSub, and burn. Native translation is on the roadmap.
