Generate captions in 50+ languages
Captions sync to your speech automatically with 98% accuracy, and you can pick from dozens of templates or customize typography, colors, and animations to match your style.
Generate AI B-roll that matches your transcript
The AI reads your transcript and inserts relevant clips from the built-in stock library or your own uploads. A simple slider controls how often B-roll appears.
Remove silences, filler words, and bad takes
Smart Trim analyzes your audio and removes dead air, filler words, and bad takes in one click, with Natural, Fast, or Extra Fast modes depending on how tight you want the edit.
Emphasize key moments with zoom
Magic Zoom adds emphasis at key moments based on your transcript, with four styles (smooth, crash, expo, linear) and AI-suggested placements you can adjust or add to manually.
Clean audio and correct eye contact
AI removes background noise and adjusts your gaze so you look directly at the camera, even when reading from a script. Both run with one click.
Save your brand kit for one-click consistency
Store your typography, colors, and caption styles once in a Brand Kit, then apply them instantly to any video for consistent output across content series or multiple clients.
