ADD CHINESE SUBTITLES
中文
Reach Mandarin-speaking audiences worldwide — burn Chinese subtitles into your videos with character-accurate AI transcription.
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
Whisper applies CJK character-level tokenization for Mandarin Chinese, producing simplified or traditional characters natively rather than pinyin romanization. The model is trained on a substantial Mandarin corpus including Putonghua and Taiwan Standard Chinese, handling tonal disambiguation effectively for accurate subtitle generation.
Hard-Burned Output
FFmpeg with libass burns Chinese 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 CHINESE SUBTITLES MATTER
The global Mandarin-speaking diaspora — over 50 million people in Southeast Asia, North America, and Australasia — actively consumes bilingual content that bridges Chinese and English. Simultaneously, Chinese creators pursuing cross-border content strategies on YouTube need burned-in subtitles to serve diaspora viewers who may not catch every spoken word in Mandarin.
Serve Chinese-speaking audiences outside mainland China
Diaspora communities in Singapore, Malaysia, Canada, and Australia actively seek Mandarin-language content on YouTube and other global platforms. Hard-burned Chinese subtitles ensure your videos are accessible to viewers watching in second-language environments where audio comprehension is harder.
Publish content that works in both language markets
Creators producing code-switching content — mixing Mandarin and English — face especially difficult subtitle challenges. Whisper handles language-mixing in a single audio track, and Autosubbed burns the resulting mixed-script subtitles directly into the video, producing a single file that works on both YouTube and bilibili-derived platforms.
Create accurately captioned Mandarin learning material
Mandarin is the most-studied second language in the world. Educational channels teaching Chinese need subtitle accuracy at the character level — a mistaken character changes meaning entirely. Autosubbed's CJK tokenization produces character-accurate output that teachers can rely on without manually auditing every subtitle block.
WHY AUTOSUBBED
WHISPER AI ACCURACY
OpenAI Whisper was trained on 680,000 hours of multilingual audio spanning 50+ languages. For Chinese, 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 Chinese 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 Chinese 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.
