Extend the length of a Runway video.
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 Extend on Pixio lengthens a Runway Gen-3 video: you provide an existing clip (and optionally a prompt to steer the continuation), and the model extends it forward (or backward where supported) while preserving look and motion. Use it when you have a Gen-3 clip that you want to make longer without re-generating from scratch.

| Mode | Input | Best for |
|---|---|---|
| Extend | Existing Gen-3 clip + optional prompt | Lengthen the clip; prompt guides continuation |
| Option | Values | Notes |
|---|---|---|
| Input | One video (Gen-3 output or compatible) | Check Pixio for max duration and format |
| Direction | Forward (typical); backward if supported | Extend from end (or start) |
| Credits | Per run or per second | Check model card in Pixio |
Credits depend on length added (or per extend run); check the model card in Pixio for current rates.
Gen-3 Turbo Extend doesn’t create new video from a still—it continues an existing clip. The model keeps the scene, character, and motion style and generates the next segment. Use an optional prompt to describe what should happen next (e.g. “camera continues to pan right”). For wider framing or aspect-ratio change, use Gen-3 Turbo Expand (Outpaint) instead.
| Scenario | Best choice |
|---|---|
| Lengthen a Gen-3 clip | Gen-3 Turbo Extend |
| Widen frame / change aspect ratio | Gen-3 Turbo Expand (Outpaint) |
| Generate new video from image | Gen-3 Turbo (Image(s) to Video) or Gen-4 |
| Long-form from scratch (e.g. Seedance extend) | Seedance 2 Pro Extend |
"Camera continues to pan right; subject walks out of frame."
"Same motion and lighting; character turns to look over shoulder."
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 Extend 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.
