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 Polish well

BurnSub uses OpenAI's Whisper-Turbo (Whisper code: pl), which has been trained on hundreds of thousands of hours of Polish speech. Accuracy on clear-audio Polish content is typically 92–97%.

Step-by-step: Polish subtitles for LinkedIn

  1. Open BurnSub. No signup needed — just drop your LinkedIn-format video.
  2. Pick Polish from the language dropdown so Whisper-Turbo transcribes accurately.
  3. Wait 30–60 seconds. The model runs locally on your GPU (or CPU as fallback).
  4. Edit captions if needed — every line is editable before burning.
  5. Pick a style from the recommended LinkedIn presets above.
  6. Burn + Download. WebCodecs encodes your video on your hardware. No upload at any step.

Frequently asked

Is auto-caption accurate for Polish?

Whisper-Turbo's accuracy on Polish 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 Polish 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 Polish, paste the translated SRT back in BurnSub, and burn. Native translation is on the roadmap.
