The document discusses using text screens and credits in a trailer to explain the story and announce production details. It describes how the first two screens set up the plot through a cliffhanger and the next two introduce the director and main protagonist. Further screens credit two actors and announce the release date, social media links, distributor and producer. The text is edited in After Effects to add a glitch effect, which is created by downloading a glitch video, adding it to adjustment layers linked to the text layers, and keyframing color changes to multiple text copies for a glitching color effect.
