How To
How to Create Karaoke-Style Captions
Word-by-word highlighting synced to speech — create karaoke captions with AI in under 5 minutes.
Step-by-Step Instructions
- 1
Upload your video or audio
Import the file you want to add karaoke captions to. The tool works with both video and audio-only files. For karaoke-style results, clear audio with distinct speech produces the best word timing.
- 2
Transcribe with Whisper AI
Let Whisper generate word-level timestamps. The precise timing of each word is what makes karaoke highlighting work — the highlight moves from word to word based on exactly when each word is spoken.
Tip: Use the small model for the most accurate word boundaries. Karaoke quality depends heavily on precise timing.

Switch to karaoke category
In the caption settings, select the karaoke category. All words appear on screen from the start of each page, and a highlight color sweeps through each word as it is spoken in the audio.

Choose your highlight style
Pick a highlight color and sub-style. Scale makes the active word pop larger. Background adds a colored fill behind the active word. Bounce gives the active word physical emphasis. Color change swaps the text color on the active word.

Fine-tune timing and export
Preview the karaoke effect in real time. Adjust individual word timing if the highlight feels early or late on any word. When satisfied, export as MP4 with the karaoke captions burned in.
01
What Are Karaoke-Style Captions?
Karaoke-style captions display all words on a page simultaneously and highlight each word in sequence as it is spoken. This creates the classic karaoke effect — text is always visible and readable, with a moving highlight that tracks the speaker's position. Unlike build-style captions where words appear one at a time, or flash captions where all words arrive together, karaoke maintains a constant text presence that viewers can read ahead of. The highlight provides the dynamic visual element, drawing the eye to the current word without hiding the surrounding context. This makes karaoke the best choice for content where viewers benefit from seeing the full sentence — interviews, podcasts, educational lectures, and song lyrics. The word-by-word highlight also creates an inherent visual rhythm that makes captioned content feel more engaging than static subtitles. VideoCaptions.AI computes highlight values per-frame using Whisper's word-level timestamps, so the movement is frame-accurate and smooth even at high speech rates.
02
Choosing the Right Highlight Sub-Style
VideoCaptions.AI offers four karaoke highlight sub-styles, each creating a different visual effect. Scale enlarges the active word slightly, making it pop out from surrounding text — this is the most popular choice and works well across all content types. Background adds a colored rectangle behind the active word, creating a strong visual marker that is highly readable even on busy video backgrounds. Bounce applies a quick physical bounce animation to the active word, adding playful energy that suits casual content and music. Color change swaps the text color of the active word, which creates a subtle but elegant highlight suitable for professional and corporate content. Each sub-style can be combined with a custom highlight color, giving you full control over the look. Consider your content's tone when choosing — scale and background are universally effective, bounce adds energy for music and entertainment, and color change maintains a polished feel for business content.
