Positioning and size

The caption block is a first-class canvas element:

The safe zone: the union of the platform UI bands leaves one clear centre bandyourseverywheretop bar ~10 %caption block ~22 %icon rail~15 %union of thesix platform UIs
  • Drag it vertically and horizontally (the block stays center-anchored on its x-position; line wrapping never changes while you move it).
  • Resize with the mouse wheel or the corner grips (50–200 %).
  • The preview shows the real line grouping and the currently spoken word highlighted — what you see is the timing the render burns in.
TIP

Keep the block inside the middle of the frame. Every platform draws its own UI over the bottom and one side, and the Video tab's safe-zone guides show exactly where — a caption that clears them clears every platform.
