How to get the best out of Runway Gen-4 Aleph
Runway Gen-4 Aleph on Pixio is Runway’s video-to-video and in-context editing model. Transform existing video: add or remove objects, change lighting, restyle the look, generate new camera angles, or create “next shot” continuations—all with text prompts and optional reference images. Max duration per run is typically ~5 seconds at higher credit cost; chain runs for longer edits. Use it when you have footage and want to change its style or content while keeping motion and timing.

Use this when
- You have existing video and want to restyle it (e.g. cartoon, painting, sketch) or change content (add/remove/replace objects, lighting).
- You need in-context editing: new angles, “next shot” in a sequence, or guided transformation from a restyled first frame.
- You want Gen-4 consistency—characters, objects, and locations preserved or coherent across the edit.
- You’re combining with other Runway tools (Act-One, Expand, 4K upscale) for a full post pipeline.
Modes in Pixio
| Mode | Input | Best for |
|---|---|---|
| Video to Video | Existing video + prompt (± reference image) | Restyle, change lighting, add/remove objects; keep motion |
| In-context edit | Video + prompt (e.g. “next shot”, new angle) | Continuations, new camera angles, guided transformation |
Options
| Option | Values | Notes |
|---|---|---|
| Duration | ~5s per generation (max per run) | Chain multiple runs for longer sequences |
| Credits | Higher per second (e.g. ~15/sec in some plans) | Check Pixio for current rates |
| Reference | Optional image | Restyled first frame or style reference to guide the transform |
Credits
Credits depend on duration and plan; Aleph typically costs more per second than image-to-video. Check the model card in Pixio for current rates.
Why Aleph fits post and restyle
Aleph doesn’t generate from a single still—it takes video in and changes how it looks or what’s in it. Use a (e.g. “make it look like an oil painting”) or a so the model carries that look through the clip. You can add/remove objects, change lighting, or generate a “next shot” that continues the action. Motion and timing stay intact; only appearance or content changes. Pair with Gen-4 image-to-video for new shots and Gen-4 Upscale for 4K delivery.
