The image
Two retired Runway help articles are the documents at hand: "Gen-2 Motion Brush," archived by the Wayback Machine on 8 December 2023, and "Creating with Camera Control on Gen-3 Alpha Turbo," archived on 25 April 2025. Each page paired short instructional text with example outputs — a still with painted motion regions for Motion Brush, a still with a directional arrow overlay for Camera Control — showing the interface state at the time of capture rather than any finished production shot.
What the documents show
The archived Motion Brush page states the tool let a user "paint over the part of your image you'd like to add motion to," then set direction in the "horizontal (x), vertical (y), and proximity (z)" axes, with one option selectable per axis. The archived Camera Control page documents six named directions — Horizontal, Vertical, Pan, Tilt, Zoom and Roll — each with a numeric intensity from -10 to 10, and states plainly that "setting all values to 0 would not result in an output with static camera motion" unless the Static Camera checkbox was also used. Runway's own current documentation adds what the archived pages could not know: its live "Gen-2 Deprecation" notice states "Motion Brush is a feature specific to the Gen-2 model, and is not available on newer models," and the Camera Control article itself now opens with "This feature is no longer available," noting Gen-3 Alpha Turbo's retirement.
Production context
As documented, Motion Brush addressed a specific gap in early image-to-video tools — pointing motion at one element of a still, such as hair or water, rather than the whole frame — while Camera Control addressed simulating a virtual camera move from a single input image and a numeric intensity value, recommended "with a text prompt for the best outcomes" per the archived article. Runway's current documentation states these named, region- or value-based controls have been replaced by prompting against newer models, which the company frames as offering "improved prompt adherence."
Reference versus imitation
Both retired tools conditioned motion on user-drawn regions or numeric values applied to a single uploaded image, not on any external creator's footage or camera work; nothing in either document claims the simulated moves match a specific physical camera or lens. A production note that cites "Motion Brush" or "Camera Control" as a current Runway capability should be checked against the company's own retirement notices before being repeated as present tense.
- Is the cited Runway feature still listed as available in the company's current help center, or only in an archived snapshot?
- Was motion specified region-by-region, as a numeric camera value, or through a text prompt?
- Does the source document claim physically accurate camera motion, or only a directional intensity setting?
Runway's own deprecation notices are a documented example of a tool vendor retiring a named visual control and stating what replaced it, which is worth recording precisely rather than assuming a once-current feature name still describes the product.
