85% of TikToks, Reels, and Shorts are watched without sound. Captions are not optional, they're essential for reach and retention. But basic static captions are no longer enough.
Animated captions that highlight each word as it's spoken (karaoke style) increase viewer retention by 30-40% compared to static subtitles. Platforms have responded: TikTok and YouTube's algorithms now favor videos with high-quality captions as an engagement signal.
