How captions work
Captions are word-timed: each word lights up as it's spoken. Pick a style in the composer (live previews) and a size — the size previews are true-scale, so what you see is what renders.
Platform safe zones
Every platform hides part of the frame under its own UI — TikTok's right rail and bottom bar, Reels' description zone, Shorts' controls. fibula maps these zones per platform and renders captions inside the safe area automatically when you export a platform variant. No more captions under the like button.
Brand Kit captions
Your Brand Kit can carry a caption look — font, colors, outline — applied across every clip. Each element (logo, handle, caption look) is individually optional, and you can drag the logo and handle anywhere on a live preview.
