● Line Breaks: Help the user, break long sentences into 2 or 3 lines to make it easier to read on the screen.

● Timing Matters: In a comedy, drama and especially the informational video caption timing needs to match emotion.

● Consistent Styling: Maintaining the same font size, color and position within a scene.
