01 · The short answer
What this Tamil subtitle generator does
Upload a video, choose Tamil, and AIVideoCaption writes the subtitles and times every word to your voice. You check them, pick a caption style, and download an MP4 with the captions burned in or an SRT file. No typing, no guessing where each line should start.
- Every word timed
Each word gets its own start and end time, so captions change exactly when you speak instead of drifting behind.
- Tamil or Roman letters
Write it in Tamil script, in Roman letters, or Tamil with the English words left in English.
- Keywords that pop
AI picks the words that carry the meaning (names, numbers, the big idea) and templates make them bigger or brighter.
- MP4 and SRT
Burned-in captions for Reels, Shorts and WhatsApp, and an SRT file for YouTube and editors.
