How to Add Captions and Subtitles to Videos with AI

Automatic captions are a transcript draft, not an accessibility guarantee. Correct language first, timing second, style third.

Workflow

1. Generate a transcript in VEED, Captions, OpusClip, or Pictory.
2. Correct names, jargon, numbers, punctuation, and speaker changes while listening to the source.
3. Add meaningful sound cues and identify speakers when the viewer cannot infer them visually.
4. Adjust line breaks around phrases, keep reading speed reasonable, and avoid covering faces or interface controls.
5. Export a reusable SRT or VTT plus a burned-in social version when needed.
6. Check synchronization at the start, middle, and end after every platform transcode.

Separate two deliverables

Animated word-by-word captions may improve social retention but can be tiring or incomplete as an accessibility track. Preserve a clean subtitle file with full language, and keep decorative emphasis optional.

For translated subtitles, use the source transcript and glossary from the video translation workflow, then obtain native review.
