Expand or outpaint a Runway video frame.
This model gets stronger as the shot becomes more explicit. Give it a subject, a move, a frame, and a mood so the output feels directed instead of guessed.
Best results start with a directed prompt or a strong first frame.
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.

| Mode | Input | Best for |
|---|---|---|
| Expand / Outpaint | Video (± prompt ± first-frame guidance image) | New aspect ratio; fill new areas seamlessly or with guidance |
| 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 depend on input duration (e.g. ~25 for ≤5s, ~50 for longer); check the model card in Pixio for current rates.
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.
Describe what should appear in the new areas (e.g. “continue the forest on both sides”, “sky and clouds above”). Or supply an outpainted first-frame image so the video expansion matches it.
"Continue the forest on both sides; same lighting and density."
"Sky and clouds above; match the horizon and time of day."
| Scenario | Best choice |
|---|---|
| Change aspect ratio / outpaint Gen-3 video | Gen-3 Turbo Expand (Outpaint) |
| Lengthen clip in time | Gen-3 Turbo Extend |
| Generate new video from image | Gen-3 Turbo (Image(s) to Video) or Gen-4 |
| Restyle existing video | Gen-4 Aleph |
Start with a strong first frame when consistency matters more than surprise.
Keep each prompt focused on one primary motion direction.
Use shorter runs for iteration, then scale up for finals.
For narratives, structure the idea as Shot 1 / Shot 2 / Shot 3 instead of one flat blob.
A strong video prompt gives the scene a subject, a move, camera behavior, and a mood to hold onto.
Start from language and push for camera intent, pacing, atmosphere, and shot design in one move.
Start from a frame or reference when consistency matters more than improvisation.
Continue or refine the clip without throwing away the visual language you already established.
Gen-3 Turbo Expand (Outpaint) works well when the prompt needs motion, framing, and visual direction, not just subject matter.
Use it for sequences that need a strong first frame, continuity, or a clearly controlled camera idea.
Treat each generation like a shot brief instead of a loose caption to get more cinematic outputs.
Start with either a directed text brief or a strong frame, depending on how locked the look already is.
Write the motion like a director: subject, action, camera behavior, environment, lighting, and tone.
Iterate fast on shorter runs, then move to stronger finals once the rhythm feels right.
Use it to build a stronger first frame, then hand that frame to the video model for motion and continuity.
Pair it with frame extraction, merge tools, or image prep so the motion workflow stays clean end to end.
