Automatic Subtitle Generation

Over 75% of short-form videos are consumed on mobile with muted audio. Explayner generates synchronized subtitles automatically:

Open the Captions tab, enable Add subtitles, and choose Original language or English (translated) for foreign audio, or scene narration for prompt videos.

Styling & Safe Margin Wrapping

  • Style Presets: Choose from bold kinetic presets, minimal lower-thirds, or boxed neon captions.
  • Safe Margins: Subtitles automatically wrap and scale to avoid platform UI overlays (TikTok buttons, YouTube Shorts titles).
  • Edit Captions: Click 'Edit captions' to adjust word boundaries or fix proper nouns, then click 'Apply captions & re-render'.
