How to Add Karaoke-Style Captions in After Effects
Karaoke-style captions highlight each word as it's spoken - the look viewers expect on TikTok, Reels, and Shorts. Here's how to build word-by-word subtitle animations in After Effects, manually or with AI.
What are karaoke-style captions?
Karaoke captions (also called word-highlight or bounce captions) display a full line of text but emphasise the word currently being spoken - usually with a colour change, scale pop, or background highlight.
Unlike static subtitles that show a whole sentence at once, karaoke captions:
- Increase retention on muted autoplay feeds
- Guide the viewer through fast dialogue
- Look native to short-form social platforms
Manual method: separate layers per word
The pure AE approach splits every word onto its own text layer, then keyframes colour or opacity per word. Accurate but extremely time-consuming.
- Transcribe dialogue and note word timings (stopwatch against audio).
- Create one text layer per word.
- Set in/out points to match speech.
- Keyframing: active word = brand colour; inactive = grey.
Time estimate: 2-4 hours for a 60-second clip. Not practical for client work at volume.
Using After Effects text animators
AE's Range Selector and text animators can highlight characters when you have per-word timing data. You still need a source of word timestamps - either manual markup or imported JSON/SRT with word-level data.
This method suits experienced AE users who want custom expressions. Most editors prefer a plugin that handles timing automatically.
AI workflow: word-level transcription + highlight presets
The practical approach for karaoke captions in 2026:
- Transcribe with word timestamps - AI returns when each word starts and ends.
- Pick a highlight animation - spotlight, highlighter bar, or colour pop.
- Set colours - base text + active word highlight colour.
- Apply to timeline - plugin generates timed text layers in a subtitles precomp.
Cuemark includes spotlight, highlighter, impact, and cascade animations designed for word-level timing. Change highlight colour and font without re-transcribing.
Popular karaoke caption styles in AE
| Style | Look | Best for |
|---|---|---|
| Spotlight | Active word scales up, rest muted | Talking-head Reels |
| Highlighter | Coloured bar behind active word | Tutorials, explainers |
| Impact | Bold pop on key words | High-energy clips |
| Colour highlight | Word changes to accent colour | Brand-safe corporate |
| Cascade | Words appear in sequence | Lyric-style content |
Pro tip: Use a pill or box background behind captions for readability on busy footage. Pair with a highlighter animation for maximum clarity on mobile.

What are karaoke captions?
Karaoke captions show the current spoken word in a different colour or style while the rest of the line stays muted. They are standard on TikTok, Instagram Reels, and YouTube Shorts.
Can After Effects do word-by-word animation?
Yes. After Effects supports per-character and per-word text animators. Caption plugins automate this by combining word-level transcription timing with preset highlight animations.
