Add a consistent, timed text layer to an existing picture-locked NodeTool timeline. Use for titles, lower-thirds, captions, callouts, and end cards, not workflow building or video rendering.

Write a shootable, precisely timed commercial beat sheet and store it as a NodeTool storyboard, with a consistent entity roster behind every shot. Use when someone needs ad structure — hooks, beats, timecodes, VO — rather than a finished render.

Turn a confirmed product or feature brief into a shootable 30–120 second explainer storyboard with a consistent entity roster. Use for explanatory product videos, not workflows, pipelines, or finished renders.

Turn a product page URL into a finished launch commercial — research, storyboard, rendered stills and clips, voice, music, an assembled timeline — delivered as an editable NodeTool project with the real cost. Use when someone asks for an ad, a launch spot, a promo or a commercial from a product page or website.

Animate typography, clips and transitions on a NodeTool timeline, and check the result by looking at rendered frames. Use for title cards, kinetic text, lower-third motion, clip entrances and exits, transitions between shots, and track layering. Not for writing the copy, cutting the picture, or rendering video.

Turn confirmed track metadata into a shootable, beat-synced music-video treatment and NodeTool storyboard. Use for music videos and promos, not workflows, pipelines, or finished renders.
