Pop-on Captions

A captioning display style in which a complete caption appears on screen as a single block, remains visible for a readable duration, and is then replaced in one transition by the next block. Pop-on captions let viewers "glance and grab" an entire sentence at once, which viewer studies consistently find more manageable than scrolling styles during fast-paced content. Pop-on is the dominant style in post-production captioning but is harder to achieve in live captioning due to latency constraints.
