Why subtitles matter for short-form video
85% of social media videos are watched without sound. Without subtitles, you're losing most of your potential audience. But generic subtitles aren't enough — animated, eye-catching captions are what stop the scroll.
FluxNote's subtitle generator creates the kind of animated captions you see on viral content — karaoke-style highlighting, neon effects, and dynamic animations that keep viewers watching.
Subtitle styles that trend on social media
FluxNote includes 25+ subtitle styles designed for social media:
- Karaoke highlighting — Words light up as they're spoken
- Neon glow — Glowing text with color effects
- Box highlight — Words appear in colored boxes
- Gradient text — Smooth color transitions
- Minimal clean — Simple, elegant text overlays
Each style can be fully customized to match your brand colors and aesthetic.
How FluxNote's subtitles compare to manual editing
Manually adding animated subtitles in Premiere Pro or CapCut can take hours per video. FluxNote generates them in seconds with AI-powered word-level timing.
The result is indistinguishable from hand-crafted subtitles — but produced 100x faster.
