Word-by-Word Dynamic Captions That Stop The Scroll
More than 80% of social feeds are scrolled on mute. VidFrame AI syncs dynamic animated subtitles directly to the spoken narration track, styled with safe-zone margins that never collide with Instagram or TikTok interface buttons.

Why Subtitles Matter For Social Retention
Social platforms prioritize average watch duration. Clear, dynamic subtitles provide visual momentum that keeps viewers watching until the final second.
Audio Waveform Sync
VidFrame AI extracts millisecond-accurate timestamps for every word in the synthesized script, ensuring the visual pop matches the spoken voice identically.
Safe-Zone Guaranteed
Captions are programmatically kept above the caption drawer, below the top profile header, and left of the right-hand action column on both Reels and TikTok.
Automatic Aspect Scaling
Whether you render a 9:16 vertical short or a 16:9 widescreen landscape video, font sizes, line wrapping, and margin heights adapt automatically.
VidFrame AI vs. Manual Subtitle Apps
No need to export video files to CapCut or Submagic just to burn in captions.
