Static captions vs kinetic captions
Static SRT-style captions tell viewers what was said. Kinetic captions — one or two words at a time, animated in sync with the voiceover — *control where the eye goes*. That single difference is worth 15–40% retention on most short-form formats.
Why this matters for 85% of viewers
85% of Reels and TikTok plays start muted. Without captions you have a wall-paper video. With kinetic captions you have a story.
