Single message
One idea, held for as long as it takes to land
One thing your product or service does, one audience, one thing to do next. The script carries a single argument from the opening frame to the closing card, and the animation is built to keep that argument moving rather than to show every screen you have.
Product walkthrough
A job inside your software, step by step
A sequence through your interface: where somebody starts, what they press, what changes on the screen and what they end up with. Screens are rebuilt as vector artwork wherever a step needs elements to move on their own, so the pace follows the explanation rather than a recording.
Extended piece
Several features or audiences in one script
More than one idea in a single piece, with the structure to keep them apart: chapters, a returning device between sections, and a close that pulls them together. Cut-downs for separate features and a captioned version for silent playback are made from the same build rather than started again.
