Why this works for X / Twitter
X captions need to work in a square or horizontal player at small sizes. High-contrast white-on-pill styles dominate news clips and viral video reposts.
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 X / Twitter algorithm reward burned captions?
Burned captions are read directly by viewers (the words appear on screen) — no AI-detection step required. X / Twitter 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.
