Caption Style
Karaoke-Style Captions: Sync-Along Subtitles for Videos
Karaoke captions keep all words visible on screen and highlight each word as it is spoken — the most readable, engagement-friendly caption style for long-form content.
What Are Karaoke Captions?
Karaoke-style captions display all words in a page simultaneously and highlight each word individually as it is spoken, creating a traveling highlight that moves through the text like a classic karaoke machine. All words are visible from the start of each page — the highlight is the only thing that changes. This makes karaoke the most readable caption category because viewers can see the entire phrase, read ahead, and follow along without text constantly appearing and disappearing. The highlight mechanism is driven by word-level timestamps from cloud AI transcription, ensuring frame-accurate sync between the spoken audio and the visual highlight. Four highlight sub-styles are available: Scale (active word grows larger), Background (colored block behind the active word), Bounce (active word jumps vertically), and ColorChange (active word switches to the highlight color).
How It Works
Karaoke captions work by rendering all word groups in a page from the start of the page's duration, rather than staggering their appearance like the Build category. Each frame, the computeHighlightValues() function compares the current playback frame against each word group's start frame (wg.from) to determine which word is active. The active word receives the selected highlight sub-style transformation, while all others display in their default state. This per-frame calculation ensures frame-accurate highlight sync that behaves identically in the live preview and exported video. The highlight color and sub-style are stored per-page in the composition data.

Karaoke vs. Pop Captions: Understanding the Key Difference
Karaoke and Pop are the two most commonly confused caption categories, and understanding the difference helps you choose the right one for your content. Karaoke keeps all words in a page visible simultaneously and moves a highlight through them as they are spoken. Pop shows one word at a time: the previous word exits as the next word enters. The practical difference is significant. Karaoke is better for content where context matters: podcast dialogue, educational explanations, song lyrics, and any content where the meaning of the current word depends on understanding the surrounding words. Viewers can see the whole phrase, read ahead, and follow along without missing context. Pop is better for content where focus matters: motivational content, product demos, high-energy clips where you want the viewer's full attention on exactly one word at a time. The visual isolation of Pop creates intense focus but sacrifices the reading comfort of seeing the full phrase. For lyric videos specifically, karaoke is almost always the right choice. The tradition of karaoke machines is to show the full lyric line with a moving highlight, and viewers instinctively understand this format. Pop captions for lyrics force the viewer to hold each word in memory while waiting for the next, which breaks the singalong experience.

Customizing Karaoke Highlight Styles for Maximum Impact
VideoCaptions.AI offers four highlight sub-styles for karaoke captions, each creating a different visual effect. The Scale sub-style enlarges the active word by approximately 110-120% of its normal size, creating a gentle emphasis that draws the eye without disrupting the layout. This is the most popular sub-style and works well across all content types. Background adds a colored rectangle behind the active word, creating high-contrast highlighting that is particularly effective for lyric videos and content where the highlight needs to be immediately obvious. The background color can be set independently from the text color. Bounce makes the active word jump vertically with a spring animation, adding playful energy suited to music and entertainment content. ColorChange switches the active word's text color to your chosen highlight color while all other words remain in the default text color. This is the most subtle option and works well for professional and educational content where you want highlighting without visual disruption. For any sub-style, choose a highlight color that contrasts with both your text color and the video background. High-saturation colors, bright yellow, cyan, or magenta, produce the most readable highlights over varied video backgrounds. The live preview in VideoCaptions.AI shows exactly how each sub-style and color combination looks before you commit to an export.

Yes. Each page has its own highlight color setting. You can use different highlight colors for different sections of your video. The highlight color and sub-style (Scale, Background, Bounce, or ColorChange) are set in the clip inspector panel for each page.
Karaoke works for any speech speed. The highlight tracks whatever speed words were spoken, driven by word-level AI timestamps. For very fast speech, the highlight moves quickly through the text. For slower speech, it moves more deliberately. If any timing feels off after transcription, you can manually adjust individual word timing in the editor.
Yes, karaoke is designed specifically with lyric videos in mind. Upload your music track, transcribe the lyrics with AI, review and correct any misheard words, then select karaoke mode. The word-by-word highlight follows the vocal timing frame-accurately, creating a professional lyric video without any manual timing work beyond reviewing the transcript.
