How to get the best out of 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.
Modes in Pixio
| Mode | Input | Best for |
|---|---|---|
| Expand / Outpaint | Video (± prompt ± first-frame guidance image) | New aspect ratio; fill new areas seamlessly or with guidance |
Options
| Option | Values | Notes |
|---|---|---|
| Input | Video (e.g. max 10s, min 620×620px) | Landscape → 768×1280 vertical; vertical → 1280×768 landscape; square can choose |
| Guidance | None, text prompt, or outpainted first-frame image | Prompt or image improves control over new areas |
| Credits | e.g. 25 for ≤5s, 50 for longer (varies by plan) | Check Pixio for current rates |
Credits
Credits depend on input duration (e.g. ~25 for ≤5s, ~50 for longer); check the model card in Pixio for current rates.
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 (e.g. create a wide canvas) then composite.
