Blocking Lock via Position Reference

A continuity technique addressing the cross-shot half of Continuity Is the Creator's Responsibility (Not the Model's): lock character/car/object blocking using an external position reference — a position-log screenshot, a hand-drawn diagram, or colored position markers — uploaded to Claude so it can be referenced when drafting each new shot's prompt. Prevents subjects from 'teleporting' between shots that are otherwise generated independently.

Position Log from Video Frames

Position Log from Video Frames

The position-reference image doesn't have to be generated fresh — it can be pulled directly from a video already generated for the scene. Screenshot a frame from an approved video (e.g. one showing a car correctly parked) and reuse that frame as the fixed spatial reference — the "position log" — for every later shot in that location.

This pairs with Video-Sequence Generation for Frame-to-Frame Consistency: because a generated video's frames are already internally consistent, a frame pulled from it makes a more reliable position reference than a separately-generated still.

Usage

After a video generation nails an object's placement in a location, pause and screenshot that frame, then reuse it as the interior/exterior positional reference for all subsequent generations in that scene.

Diagram and Marker-Based Variants

When purely textual position language fails to control blocking — cars or actors drifting or 'teleporting' between shots — the fix is a visual reference rather than a better-worded prompt. Two low-tech variants are used alongside screenshotting an approved video frame as the position log:

Both work because spatial/visual instruction outperforms verbal description for blocking control — the model matches a drawn mark or line far more reliably than it parses 'park facing north, three car-lengths from the curb.'
