Why it matters
Less busywork, more videos
The key word stands out
In “Smart” mode the AI highlights one word, number or name in each line — eyes catch the meaning, not just the letters.
Adjust with your finger
Drag the caption anywhere in the frame, pinch to resize, pick a color from the palette or right from the frame with the eyedropper. Edit the text too.
