AI Caption Generator FAQs

What is an AI caption generator?

An AI caption generator listens to the audio in your video, transcribes it and places the words on screen, timed to the speaker. invideo does all three automatically, then styles the text with animation instead of a plain subtitle bar. The captions land on the timeline as an editable track, so you can fix a word or restyle a line without retyping anything.

How do I add captions to a video on invideo?

Go to the Trends tab on your dashboard and select Dynamic Captions. Pick one of the 10+ caption styles, upload a video or choose one from your existing invideo projects, and invideo transcribes and syncs the text for you. Preview it, edit the transcript or styling if you want, and export in up to 4K.

Is AI caption generator free on invideo?

Yes, you can generate captions on the free plan. Free accounts include a monthly allowance of generation credits and exports carry a watermark. Paid plans remove the watermark, raise the credit limit, and increase export resolution. Full details are on the pricing page.

What languages does it support?

invideo transcribes and captions in 50+ languages, including English, Spanish, French, German, Portuguese, Hindi, Arabic, Japanese, Korean and Mandarin. You can caption in the language spoken in the video, or translate the captions to reach a different market without re-recording anything.

What caption styles are available on invideo?

There are 10+ animated presets, including scroll text, bold text behind, scribble effects and gradient overlays. Each one is a starting point rather than a fixed template. Font, colour, size, position and animation are all editable, so you can match a brand kit or change the look per video.

Can I edit captions on the timeline?

Yes. Captions sit on their own track in the invideo editor. Edit the transcript, move or restyle individual lines, or ask the agent for a change. When you trim the video, the captions re-time to match.

Do captions help with video engagement?

Yes. Most social video is watched on mute, so captions are often the only way the message lands. Adding them can improve watch time and completion rate on short-form platforms, and they make your content accessible to viewers who are deaf or hard of hearing, or watching in a second language.

How accurate is the auto-transcription?

It handles fast speech, strong accents, background noise and multiple speakers well. Accuracy drops on heavily overlapping dialogue or very poor audio, which is why the transcript is fully editable before you apply a style. Fix any names or jargon in the transcript and the timing stays intact.

Use invideo MCP to create and add captions for videos with LLMs

Connect invideo to the LLM you already use through MCP. Ask it to caption a video, edit the style or translate in a different language, and it gets the work done in the same chat and creates it on a timeline as well.
