Gen-3 Turbo Expand (Outpaint)

Pixio briefing

How to get the best out of Gen-3 Turbo Expand (Outpaint)

Prompt to Motion

Best when you want to direct the whole shot from language.

New scenes, camera intent, atmosphere-first ideation.

Reference Control

Best when the first frame or reference look needs to stay locked.

Keyframes, product shots, character continuity, style anchoring.

Scale to Finals

Best when the clip already works and you want more control instead of a reroll.

Continuations, polish passes, cleanup, stronger finals.

Gen-3 Turbo Expand (Outpaint)

Gen-3 Turbo Expand (Outpaint) on Pixio expands a Runway Gen-3 video beyond its current frame—e.g. turn a horizontal clip into vertical (or vice versa) or add content on the sides. You can let the model fill the new area seamlessly, or provide a text prompt or outpainted first-frame image to guide what appears. Use it when you need a different aspect ratio or a wider view without re-shooting.

Use this when

You have a Gen-3 clip and need a different aspect ratio (e.g. landscape → vertical for social, or vertical → landscape).

You want to outpaint—add content beyond the current frame edges—with seamless or guided fill.

You’re reformatting for platform (e.g. 16:9 → 9:16) and want the model to generate the new areas.

You have an outpainted still of the first frame and want the video expansion to match it.

Why expand vs extend

Extend (Gen-3 Turbo Extend) lengthens the clip in time. Expand (this tool) widens or reframes the clip—new pixels at the sides (or top/bottom) to change aspect ratio or add space. Keep subjects centered in the original for best expand results; avoid heavy text or graphics in the frame. You can expand multiple times (e.g. create a wide canvas) then composite.
