Runway Gen-4 Aleph (first-party).
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.
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.

| 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 |
| 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 depend on duration and plan; Aleph typically costs more per second than image-to-video. Check the model card in Pixio for current rates.
Aleph doesn’t generate from a single still—it takes video in and changes how it looks or what’s in it. Use a text prompt (e.g. “make it look like an oil painting”) or a stylized first frame 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.
| Scenario | Best choice |
|---|---|
| Restyle or edit existing video | Gen-4 Aleph |
| Generate new video from image | Gen-4 (Image to Video) or Gen-4 Turbo |
| Cinema-grade from scratch or keyframe | Seedance 2 Pro |
| Quick draft from image | Kling or Gen-4 Turbo |
| 4K upscale | Gen-4 Upscale |
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.
Runway Gen-4 Aleph 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.
