ADD KOREAN SUBTITLES
한국어
K-content has gone global — burn Korean subtitles into your videos and serve international fans who expect captions on every upload.
THREE STEPS TO SUBTITLED VIDEO
Upload Your Video
Drop your MP4 or MOV file directly into Autosubbed. Files up to 500 MB are accepted, covering footage from phones, cameras, and screen recorders — no conversion needed.
AI Transcription
Korean is well-represented in Whisper's training data, with the model producing native Hangul script output rather than romanized transcription. The agglutinative morphology of Korean — where grammatical particles attach to nouns and verbs — is handled correctly, producing readable subtitle segments rather than broken mid-morpheme splits.
Hard-Burned Output
FFmpeg with libass burns Korean subtitles directly into the video pixels at the frame level. The result plays identically on every platform, device, and player — no dependency on subtitle track support.
WHY KOREAN SUBTITLES MATTER
The global K-drama and K-pop phenomenon has created an unprecedented international fanbase actively seeking Korean-language content with accurate subtitles. International viewers watching Korean creators on YouTube and Twitch treat subtitles as a baseline expectation, not an optional feature — creators without captions lose a significant portion of this high-engagement global audience.
Give international fans the Korean captions they expect
Korean YouTube creators with international fanbases know their viewers follow along via subtitles. Hard-burning Korean captions ensures fans in the US, Europe, and Southeast Asia can read along accurately — without relying on YouTube's auto-caption system, which frequently mistranscribes Korean at high speaking pace.
Produce captioned Korean lessons for students worldwide
Korean language instructors on YouTube and Patreon need subtitle accuracy at the syllable block level — a single misrendered Hangul block changes the lesson entirely. Autosubbed delivers Hangul-accurate captions burned permanently into lesson videos, ready to publish without a separate caption upload step.
Caption fast-paced Korean variety content for global reach
Korean variety shows and entertainment channels move quickly, with rapid dialogue and overlapping speech. Whisper's speed-robust transcription handles fast Korean speech better than most ASR tools, producing subtitle timing that matches rapid delivery without cutting off sentence endings.
WHY AUTOSUBBED
WHISPER AI ACCURACY
OpenAI Whisper was trained on 680,000 hours of multilingual audio spanning 50+ languages. For Korean, this means state-of-the-art transcription accuracy that auto-detects the language without any configuration. No language hint required — upload and go.
UNDER 60 SECONDS
GPU-accelerated cloud processing means a 10-minute Korean video — transcription, SRT generation, and FFmpeg burn — is ready in under 60 seconds.
CUSTOM STYLES
Choose fonts, colors, weight, and positioning before burning. Match your brand or channel aesthetic — every style choice is encoded permanently into every frame.
PERMANENT HARD BURN
Unlike SRT tracks that platforms ignore or display incorrectly, Autosubbed uses FFmpeg to embed Korean subtitle text directly into the video pixels at the frame level. The result plays identically on YouTube, Instagram, TikTok, LinkedIn, and every other platform — with zero dependency on subtitle track support.
