Why this works for Instagram Reels
Reels users skew design-conscious. Minimal centered captions with subtle backgrounds outperform garish styles on Instagram's algorithm.
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%.

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 Instagram Reels algorithm reward burned captions?
Burned captions are read directly by viewers (the words appear on screen) — no AI-detection step required. Instagram Reels 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.
