Auto Caption Generator
Auto caption generator tuned for performance video ads, not random vlogs. When you need Facebook ads captions for paid social tests, Sovran transcribes your voiceover with frame-level accuracy, styles captions in your brand colors, and burns them in for every ad variant in one pass.
Frame‑accurate sync, no manual tweaking
Captions land on the exact frame the word is spoken. No more dragging timeline blocks five frames left.
Brand‑styled, not stock TikTok captions
Set caption font, color, stroke, and animation once. Every ad variant uses the same caption style without redoing it.
50+ languages, accurate transcription
Auto-caption Spanish, German, Portuguese, French, and more. Switch language without retyping a single word.
One render, all aspect ratios
Captions reflow for 9:16, 1:1, and 16:9 automatically. Stay safe inside the action zone on every platform.
Test caption variations like ad copy
A caption rewrite often beats a new edit. Run caption variations through testing alongside hooks and CTAs.
Captions on every video, every render
Auto-caption fires on bulk renders, not just one-offs. Facebook ads captions stay applied when you ship a hundred captioned video ads as fast as you ship one.
