Professional video tool

AI Video Caption Generator

Auto-transcribe spoken video, style timed subtitles, and export a new clip with readable captions burned in.

Lucidpic turns speech into timed captions and renders them directly into a reusable video output. Choose a caption template, tune the position and phrase length, preview the transcript, and create a captioned copy while keeping the original video.

Linked, non-destructive outputCaption Tool costs 1 credit when you render the captioned video.

How it works

A focused workflow, not another blank canvas.

Each tool asks only for the controls that matter to the job and saves a new reusable media result.

  1. 01

    Choose a video with clear speech

    Select an uploaded or generated video from your Lucidpic library. Clear dialogue with limited background noise produces the most useful transcript.

  2. 02

    Transcribe and style the captions

    Generate the transcript, review the timed text, choose a caption template, set the position, and control how many words appear in each phrase.

  3. 03

    Render and review the video

    Burn the styled captions into a new video, then check wording, timing, line breaks, safe areas, and contrast before publishing.

Know the limits before you publish.

  • Automatic transcription can mishear names, brands, accents, overlapping speech, or dialogue under loud music. Review the transcript before rendering.
  • Burned-in captions become part of the video pixels and cannot be toggled off by the viewer.
  • Caption timing and line breaks may need adjustment for fast speech or unusual pacing.
  • The workflow creates open captions in a new video; it does not export a separate SRT or VTT subtitle file.

Practical details

Frequently asked questions

How does the AI video caption generator work?

Choose a video, let Lucidpic transcribe its spoken audio, review the timed text, select a visual template and layout settings, then render a new video with captions burned in.

Do I need to write captions manually?

No. Caption Tool automatically generates a timed transcript from the video audio. You should still review names, brands, punctuation, and any words affected by noise or accents.

Can I choose different caption looks?

Yes. Choose from the available caption templates, then tune position and phrase density to suit the video format and pacing.

Can I control how many words appear at once?

Yes. The tool supports between one and six words per caption phrase, which helps balance fast word-by-word emphasis with calmer multi-word subtitles.

Are captions permanently added to the video?

Yes. The captions are burned into a new video output, so they remain visible on any platform. The original uncaptioned video stays available in your library.

Does the tool export SRT or VTT subtitle files?

No. The current workflow creates open captions rendered into the video rather than a separate subtitle file.

What videos transcribe most accurately?

Videos with clear speech, limited background music, minimal overlapping dialogue, and a good recording level generally produce the cleanest transcript.
