RunAleph

RunAleph is a free online platform that lets users edit and generate videos using Runway Aleph, a next-generation AI video model built on advanced Gen-4 technology. It allows creators to transform existing videos with simple text prompts, making professional-level video editing accessible to anyone. With no downloads and no editing experience required, RunAleph helps users create high-quality visuals directly from their browser.

At its core, Runway Aleph focuses on in-context video editing, meaning the AI understands the content, lighting, motion, and composition of a video before making changes. Users can add, remove, or transform objects, restyle scenes, relight environments, or even generate new camera angles like wide shots or over-the-shoulder views—without reshooting footage. This gives creators more flexibility and creative control while saving time and production costs.

RunAleph also supports video-to-video generation, allowing users to reimagine scenes, apply new styles, or change the mood of a clip using a single prompt. With features like motion transfer, still images can be brought to life by applying movement from other clips. The platform also includes background and subject isolation without the need for a green screen, preserving fine details for clean and professional results.

Used by filmmakers, marketers, educators, and content creators, RunAleph is ideal for cinematic storytelling, product and ad videos, social media content, and visual effects experimentation. Its clean output includes no watermark and supports private generations, making it suitable for both personal and professional use.

And the best part? RunAleph offers a free plan that includes 20 credits to generate videos, allowing users to explore Runway Aleph’s powerful AI video editing capabilities at no cost and start creating instantly.
