Dynamic captions

What are dynamic subtitles and why do they matter?

Dynamic subtitles go beyond simple text overlays. They animate word by word in sync with the audio, using motion effects, colour changes, and emphasis animations to create a visually engaging reading experience. Think of them as the evolution of static captions.

On social media, dynamic subtitles increase viewer retention by up to 40%. They give sound-off viewers a reason to keep watching, transform spoken words into visual content, and add a layer of production value that distinguishes professional clips from amateur ones.

Choppity generates dynamic subtitles automatically for every clip. The AI transcribes your audio with precise word-level timing, then applies your chosen animation style. The result is broadcast-quality animated captions without any manual keyframing.

Caption styles

Animated caption styles for every brand and platform

Choppity offers a library of dynamic subtitle styles. Word-by-word highlight illuminates each word as it's spoken. Colour burst adds an accent colour to keywords for emphasis. Bounce makes words pop onto screen with elastic motion. Fade brings words in smoothly. Typewriter reveals text character by character.

Each style is fully customisable. Change fonts, colours, sizes, and positioning to match your brand. Save your preferred settings as a preset and apply them to every future clip with a single click.

Different platforms favour different aesthetics. Bold impact text dominates TikTok. Clean lower-thirds work best on LinkedIn. Choppity's style variety means you can match the vibe of each platform while maintaining your visual identity.

Accuracy

AI transcription that powers accurate dynamic subtitles

Dynamic subtitles are only as good as the transcription behind them. Choppity's AI achieves over 95% accuracy for clear audio, handling multiple accents, speaking speeds, and audio environments reliably.

Word-level timing is critical for animated captions. Each word must appear at precisely the right moment — too early and the animation leads the audio; too late and it lags behind. Choppity's timing engine synchronises animations to within milliseconds of the spoken word.

The text-based editor lets you review and correct every word before export. Fix any transcription errors, adjust timing, and see the changes reflected in the animated preview instantly. This ensures your dynamic subtitles are both accurate and beautifully timed.

"In the past I've tried to get my YouTube video editor to create mass amount of short form content, but they struggled. Economically it didn't make sense and the quality wasn't great. Choppity has been an INCREDIBLE asset in scaling up my short-form video reach. Having ALL the clips automatically clipped, styled and ready to publish has been the biggest lever to growing my businesses."
