Detailed feature breakdown

How Captions, Audio & AI Voice works inside Lyra Video Editor.

This section explains the actual workflow, controls, and buyer value behind this feature.

Caption layers with detailed style controls

The caption feature supports generated caption words and imported SRT timing. Captions can be styled with reveal modes, word counts, highlight effects, stroke, shadow, alignment, direction, case transforms, and text animation options.

  • SRT upload turns subtitle files into editable caption layers.
  • Generated captions can carry word timing and reveal behavior.
  • Highlight and text styles help match brand and social format needs.

Audio upload and voice generation

Creators can add uploaded audio or generate AI voiceovers through text-to-speech provider settings. Audio assets can be placed on timeline tracks and managed alongside video, image, caption, and text layers.

  • Audio upload supports voiceovers, music, and sound effects.
  • Text-to-speech options can use provider and model settings configured by the workspace.
  • Audio layers are part of the same timeline workflow as visual layers.

Mixing controls for timeline output

Audio and video items include practical controls such as volume, mute, fade-in, and fade-out. These controls are important for short social videos where voice, background audio, and clip sound need to be balanced before export.

  • Volume and mute controls are available on media layers.
  • Fade controls support cleaner intros and endings.
  • Audio settings remain connected to final render output.
