Runway 4K video upscale: increase resolution of your clip to 4K while preserving detail and reducing artifacts.
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-4 Upscale (4K) on Pixio is Runway’s 4K video upscale. You input a clip (e.g. 720p or 1080p) and the model increases resolution to 4K while preserving detail and reducing artifacts better than simple interpolation. Use it when you have a final cut and need delivery-ready 4K for broadcast, cinema, or high-res display.

| Mode | Input | Best for |
|---|---|---|
| Upscale to 4K | One video file (e.g. 720p, 1080p) | Increase resolution to 4K with detail preservation |
| Option | Values | Notes |
|---|---|---|
| Input | Video (typical formats) | Check Pixio for supported codecs and max duration |
| Output | 4K | Resolution target; aspect ratio preserved |
| Credits | Per second or per run | Check model card in Pixio |
Credits depend on input duration (or per run); check the model card in Pixio for current rates.
Most video models output at 720p or 1080p. For 4K delivery you either need a native 4K model (rare) or an upscale step. Gen-4 Upscale is tuned to retain detail and reduce artifacts—better than a simple resize—so your final export is suitable for high-res use. Run it as the last step after you’re happy with the edit and style.
| Scenario | Best choice |
|---|---|
| Upscale existing video to 4K | Gen-4 Upscale (4K) |
| Generate new video | Gen-4, Seedance, Kling, Veo, etc. |
| Restyle or edit video | Gen-4 Aleph or Grok Imagine |
| No 4K requirement | Skip upscale; use native resolution |
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-4 Upscale (4K) 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.
