Why captions are non-negotiable
Great captions aren't decoration — they decide whether your video gets watched at all.
Most people watch on mute
On feeds, the sound is off by default — captions are often the only way your message lands.
They lift retention & saves
Word-synced captions keep viewers reading to the end and coming back.
Everyone can follow along
Captions make your videos accessible to viewers who are deaf or hard of hearing.
Tips for captions that hold attention
Keep it to 2–3 words on screen at once — easy to read at a glance.
Go high-contrast — bold text with a strong outline or box reads on any clip.
Sync to the beat — word-by-word timing pulls the eye and holds attention.
Pick one accent color and stick to it — consistency looks intentional.
