Gen-4 Aleph
Runway's most reference-capable Gen-4 variant. Generate video from multiple image and video inputs simultaneously — the choice for reference-heavy creative briefs and visual consistency requirements.
What is Gen-4 Aleph?
Gen-4 Aleph is a specialized variant in Runway's Gen-4 family focused on multi-reference generation. Where Gen-4 Turbo optimises for speed and Gen-4.5 for quality, Aleph is designed for workflows that require multiple visual reference inputs to be synthesised into a single coherent output.
You can provide multiple image references — character shots, environment images, style examples — alongside a video reference clip. The model incorporates all of these into the generation, producing output that reflects the combined visual context of your references rather than just the text prompt alone.
This is valuable for brand-consistent production, character-driven content, and any scenario where maintaining visual consistency with existing assets is a requirement. Gen-4 Aleph bridges the gap between text-to-video generation and reference-anchored production workflows.

How to generate video with Gen-4 Aleph on project.video
Open the composer
Navigate to your project.video dashboard and open the composer. Gen-4 Aleph is available in the Runway model section.
Select Gen-4 Aleph
Choose Gen-4 Aleph when you have reference images or videos that need to inform the generation. The composer shows all available input slots.
Upload your references
Add multiple image references — subject shots, environment images, style examples — and optionally a video reference clip. These form the visual context for the generation.
Write your prompt and generate
Describe the output you want in your text prompt. The model synthesises your references with your prompt to produce a coherent, reference-guided output.
Technical specs
Best use cases
Brand-consistent campaign video
Supply brand asset images — product shots, approved color environments, visual style references — and a style reference video. Gen-4 Aleph synthesises them into output that stays on brand.
Character continuity across clips
For campaigns featuring a consistent character, provide multiple reference images from different angles. Gen-4 Aleph maintains character consistency across generations better than text-only descriptions.
Style matching for content series
Provide an existing video from your content series as a reference alongside new scene images. Gen-4 Aleph generates new clips that match the established visual style of the series.
Mood board to video
Collect your creative brief's mood board images and use them directly as multi-image references. The model translates your visual inspiration into a generated output rather than requiring you to describe it in text.
Example prompts
These prompts pair best with reference images and video inputs in the project.video composer.
"Fragrance brand film: a figure in tailored clothing moves through a sun-drenched Italian courtyard, consistent with provided character and environment reference images, matching motion style from reference clip, 16:9"
"Tech product launch video: device floats on dark surface, light plays across surfaces consistent with provided product references and brand style images, slow rotation, 16:9"
"Interior design showcase: camera drifts through a space that reflects provided material samples and architectural reference images, morning light quality from mood board reference, 16:9"
