Runway Aleph
Professional Video-to-Video Editing

What is Runway Aleph?
Runway Aleph is a professional in-context video editing model designed for advanced video-to-video transformations. Built by Runway as their flagship editing solution, Aleph represents a paradigm shift in AI-powered video editing by enabling text-driven modifications while preserving the original motion and timing of source footage.

Prompt Compatibility
Aleph requires prompts that focus on transformations and changes rather than describing existing content. Best practices include focusing on modifications (e.g., "transform into watercolor style" rather than "video of a person walking").
Best Practices:
- Focus on modifications, not descriptions
- Include camera movement descriptions
- Add temporal elements ("gradually", "smoothly", "suddenly")
- Specify lighting/atmosphere changes
Transformation Types:
Style transfers, object additions/removals, lighting adjustments, weather changes, artistic effects. Optional reference images can guide style or appearance.

Workflow guidance
Practical notes for teams routing this model inside Cliprise—written for planning and QA, not as performance guarantees.
Best use cases
- Relighting or restyling plate footage while keeping performer motion intact.
- Iterative storyboards derived from existing takes instead of regenerating from scratch.
- Director revisions when timing is locked but visuals need exploration.
Prompt ideas
- Describe edits relative to on-screen action (“swap jacket color,” “warm evening grade”).
- Anchor prompts on preserved motion (“keep choreography, change backdrop”).
- Layer references when asking for stylistic alignment rather than brand-new motion.
Best practices
- Export trims that isolate the seconds you truly need—Aleph shines when edits target clear beats.
- Document seeds when creative directors approve a look so revisions stay consistent.
- Keep backup masters before destructive replacements downstream.
Limitations
- Not meant for fully synthetic worlds without base footage.
- Heavy occlusion changes may require multiple passes or companion tools.
- Always validate licensing for supplied footage before transforming.
How it compares
Runway Gen4 Turbo remains the generation-forward lane for fresh clips from prompts or references. Aleph is better when you already have footage worth preserving and only need guided transformations—mix both inside Cliprise depending on production phase.

FAQ
- Aleph versus Gen4 Turbo—how do I choose?
- Start from footage + transformation prompts → Aleph. Need net-new motion from prompts → Gen4 Turbo or another VideoGen pick.
- Can Aleph replace my NLE?
- Treat it as a specialized transformation step—audio finishing, conform, and delivery still belong in traditional editors.
- What footage works best?
- Stable plates with readable subjects typically iterate faster than noisy handheld clips.
