Intertitle

In films, an intertitle, also known as a title card, is a piece of filmed, printed text edited into the midst of (i.e., inter-) the photographed action at various points. Intertitles used to convey character dialogue are referred to as "dialogue intertitles", and those used to provide related descriptive/narrative material are referred to as "expository intertitles"https://en.wikipedia.org/wiki/Intertitle
