Runway Aleph AI Generator
Generated on PixelDojo with Runway Aleph. Produced by PixelDojo's generation pipeline.
Runway Aleph costs 7 credits per second of the video_duration you declare in the request, and that field does not have to match the actual length of your source clip. We tested it on August 26, 2026 with the schema's 2-second minimum, which cost 14 credits and finished in about 176 seconds, but the model still transformed and returned the full length of our source clip regardless. This page covers that billing behavior, the fact that Aleph needs an existing video rather than a starting image, and how it prices against PixelDojo's other video-editing tools.

Runway Aleph
The test, and the billing quirk it exposed
It needs a video, not an image
Runway Aleph's request schema has a video field and a prompt field. There is no image field at all, so it cannot animate a still photo the way VEO or WAN can. It transforms footage you already have.
The setup
We fed it a real 960x960, about 5-second product clip and a prompt asking for a warm cinematic color grade and light bloom, with video_duration set to 2, the schema's minimum.
What it cost
7 credits per second of the declared video_duration. At the 2 second minimum, that is 14 credits.
What it measured
About 176 seconds from request to finished file. The returned clip came back at 1088x1088, 30fps, about 5.02 seconds long, roughly 1.95MB.
The billing field is not a duration limit
We declared and were billed for 2 seconds, but the output was not trimmed to 2 seconds. It came back at the full length of our roughly 5-second source clip. The video_duration field sets the price; it does not cap or guarantee the output length.
Keyframe images add pinpoint control
Up to 5 keyframe_images can be sent alongside the video, each paired with a position of first, last, or a specific timestamp, for image-level control over the edit beyond what the prompt alone can steer.
One video-to-video test, August 26, 2026. Declared 2 seconds, billed 14 credits, about 176 seconds, and the full source clip came back transformed.
Why Choose Pixel Dojo for Runway Aleph
Professional-quality results with cutting-edge AI technology
14 credits at the schema minimum
7 credits per second times the 2-second minimum video_duration, measured on our August 26, 2026 run.
Restyles footage you already have
No image-to-video path here. It is built to transform an existing clip with a text prompt.
Keyframe images for extra control
Pin up to 5 reference images to specific points in the timeline alongside the transform prompt.
How It Works
How we ran the test, so you can repeat it:
Start from an existing video, not an image
We fed it a real product clip we already had. There is no image field in this schema to animate a still photo from.
Write the transform as an instruction
Our prompt asked for a color grade and light bloom while explicitly keeping the composition and motion unchanged.
Run it in the app or over the API
Generate from the Runway Aleph page, or POST to /api/v1/models/video-transform/run. Ours declared a 2 second video_duration, charged 14 credits, and took about 176 seconds.

Common Questions
Everything you need to know about Runway Aleph
What does Runway Aleph cost?
7 credits per second of the video_duration you declare, from 14 credits at the 2 second minimum up to 210 credits at the 30 second maximum. That field sets the bill; it is not a strict limit on how much of your source clip gets processed.
How fast is Runway Aleph?
About 176 seconds for our 2-second-declared test on a roughly 5-second source clip, measured on August 26, 2026. Turnaround moves with queue load.
Can I use a photo instead of a video as the starting point?
No. The request schema requires a video URL and a prompt; there is no image field. For animating a still photo, use an image-to-video model like VEO 3.1 or WAN instead.
Does declaring a short video_duration limit the output length?
Not based on our test. We declared 2 seconds, the schema minimum, and were billed 14 credits, but the returned clip still ran the full roughly 5 seconds of our source video rather than being cut down to 2.
How does it compare with Video Reframe or Video Autocaption?
Video Reframe changes aspect ratio at 1.5 credits per second. Video Autocaption burns in captions for a flat 5 credits. Runway Aleph is the most expensive of the three at 7 credits per second because it restyles the actual video content with a text prompt.
How do I call it from the API?
POST to /api/v1/models/video-transform/run with your API key, a video URL, a prompt, and a video_duration between 2 and 30.
