How to Add Captions to Any Video with AI
A lot of social video is watched on mute — captions aren't decoration, they're the difference between a view and a skip. Here's how to caption any video in one request, styled exactly how you want.

The old cost was real: typing captions by hand or wrestling subtitle files and timing. With an agentic editor, captions are one line of a request — and they arrive styled, timed, and burned in. If your captioned clips start life as long recordings, see how to turn long videos into clips.
What Caption Styles Does Valmera Support?
Valmera captions support karaoke word-pop, fade / pop / slide-up entrance animations, sizes from S to XL on a continuous scale, bottom / middle / top placement, and any color — all timed word-by-word from a Deepgram nova-3 transcript.
Use chat to request a style or correction; the full reference is in the captions docs. Review the rendered captions against the audio, especially names, numbers, overlapping speech, and the first and last word of each phrase. Correct the transcript, render again, and check readability at the intended viewing size. Captions are burned into the Studio MP4; a successful edit record alone does not establish that every word or timing is right.
The Workflow
Upload the video
Any talking video up to 14GB: a Reel, a tutorial, a podcast clip, a product demo. MP4, MOV, MKV, or WebM.
Describe the caption style
Color, size (S–XL), position (bottom, middle, top), karaoke word-pop, and an entrance animation — fade, pop, or slide-up. Copy an example request below to start.
Review the preview
Check accuracy and look. The agent transcribed, timed, styled, and rendered in one pass — previews use a fast proxy, and the final export renders from your original full-quality file.
Fix anything by talking — or in the transcript
"Make the captions 20% bigger." "Move them to the middle." A wrong word gets fixed right in the editable transcript panel, and the captions re-render.
Export
Download the captioned MP4, ready for any platform. Ask for a 9:16 vertical version in the same session if you need one.
Example Requests to Copy
Got a Word Wrong? Edit the Transcript
You never juggle SRT or VTT files with Valmera — the transcript itself is the subtitle source, and it's editable. Open the transcript panel, fix the word the model misheard — a product name, a technical term, a mumbled number — and the captions re-render with the correction, already timed to the audio. No exporting, re-syncing, or re-uploading a subtitle file.
Captions also pair naturally with a reframe: ask for a 9:16 version and the same captions render on the vertical cut. Captioning uses credits from a paid plan. Account creation and uploads are free; processing and revisions determine editing usage.
