Scroll Sequence
Core has nothing like this: Cover can fix a background, Video plays on its own clock. This block draws a sequence of images on a canvas and plays it with the scroll — pinned on screen while it plays, or as it passes in the content — or by itself, or following the pointer. Frames come from the media library, a folder of numbered images or a video (taken frame by frame in the browser). Text appears and leaves at chosen points, with a progress bar and a frame counter; frames load in a spread-out order so scrubbing works from the first moment. Visitors who prefer reduced motion (and anyone without JavaScript) see a still poster with the texts listed over it.
Ready-made patterns
Inserter → Patterns → Moduly. The 60 day-to-night frames are illustrations bundled with the block. Keep scrolling: the first one is pinned for four screens.
