Apa yang Anda dapatkan

Caption quality that matches pro editors

Word-accurate timing

We use word-level timestamps from speech recognition or YouTube captions - each word appears exactly when it's spoken, not a second off.

Styled for short-form

Captions are sized, positioned, and styled to match modern Shorts aesthetics - bold, readable at a glance, never obstructing faces or key content.

Fully automatic

No SRT upload, no manual sync, no caption editor. Captions are generated and burned into every clip without you lifting a finger.

Multi-language support

We support 99 languages - if your video has spoken audio, we can transcribe and caption it.

High contrast rendering

White text with a black outline ensures captions are readable on any background - bright beaches, dark stages, or anything in between.

Burned-in permanence

Captions are rendered into the video file itself - they appear everywhere: feeds, stories, embeds - no platform support required.

Cara kerjanya

From transcript to burned-in captions

01

Transcript with word timestamps

YouTube captions or speech recognition produces a full word-level transcript - every word tagged with its exact start and end time in the source video.

18,432 words with timestamps
02

Caption segmentation & styling

The AI groups words into natural-reading segments that fit the screen. Font size, position (lower third), and style (Impact with outline) are applied to match pro short-form standards.

Caption segments styled
03

FFmpeg burn-in render

FFmpeg overlays the caption ASS/SRT stream directly onto the video pixels - permanently part of the file. The final MP4 plays with captions on any device, any platform, any player.
