Quick answer

To add animated captions to a video, upload your clip to AnimateCaptions, let it auto-transcribe and time-sync each word, then pick an animated style that reveals or highlights words as they're spoken. Customise the highlight colour, font, and position, and export a burned-in MP4 rendered at full resolution. The word-level timing from the transcript is what drives the animation.

Step by step

How to add animated captions in 5 steps.

Auto-synced word timing to a burned-in animated MP4.

  1. 01

    Upload your video

    Drag an .mp4 or .mov into the browser. Clips up to 2 minutes and 500 MB are supported on the free tier.

  2. 02

    Let it transcribe

    Deepgram Nova-3 transcribes the audio automatically and time-syncs every word — the timing the animation rides on.

  3. 03

    Pick an animated style

    Choose from 32+ animated presets. Each one reveals and highlights words in sync with the speech — word-by-word pop, colour highlights, scaling, and more.

  4. 04

    Customise the animation

    Change the highlight colour, font, size, stroke, and per-line position. The live preview plays the animation exactly as it will export.

  5. 05

    Export the animated MP4

    Export a burned-in MP4 rendered with Remotion at full resolution — the animation is baked into the frames, no quality loss.

Common questions

Animated captions — FAQ.

What are animated captions?

Animated captions are on-screen subtitles that move in sync with speech — typically revealing or highlighting one word at a time, scaling, or changing colour as each word is spoken. They hold attention better than static text, which is why short-form creators use them.

How do I add animated captions for free?

Upload a video to AnimateCaptions, let it auto-transcribe, pick an animated style, and export. The free tier has no credit card; free exports carry a small watermark, and paid plans from $7.99/month remove it.

Can I control the animation style?

Yes. There are 32+ animated presets, and you can change highlight colour, font, size, stroke, and the position of each line before exporting.

What makes word-by-word captions effective?

Revealing one word at a time keeps the viewer's eye moving and reinforces the spoken audio, which improves retention in the first few seconds — the window that decides whether a clip gets pushed.

Are the animated captions burned into the video?

Yes. The animation is rendered into the video frames and exported as a standard MP4, so it plays identically on every platform with no separate file.

Does adding animation reduce video quality?

No. Exports are rendered server-side with Remotion at full resolution, so the animated captions are added without re-compressing or downgrading your video.
