Runway Gen-1 Guide: Features and How to Use

The Evolution of Video-to-Video AI: A Deep Dive into Runway Gen-1

When generative artificial intelligence first captured public attention, the focus was heavily skewed toward text-to-image tools. However, the creative landscape shifted dramatically when Runway—one of the co-creators behind Stable Diffusion—introduced Gen-1.

Unlike traditional models that build videos purely from scratch using text prompts, Gen-1 pioneered a revolutionary approach: video-to-video translation. By applying the composition, style, and structure of text prompts or reference images to existing source footage, Gen-1 opened up brand-new possibilities for creators, filmmakers, and digital artists.

What Makes Runway Gen-1 Unique?

At its core, Gen-1 is a content- and structure-guided video diffusion model. Instead of requiring complex CGI pipelines or tedious frame-by-frame manual editing, the model allows users to reshape an already recorded video using simple descriptive text or input images.

As Runway famously put it, it is akin to “filming something new, without filming anything at all.”

The Five Core Generation Modes

Gen-1 delivered versatility through five distinct operating modes, each tailored to specific production needs:

• Stylization: Seamlessly transfers the artistic style of any image or text prompt onto every single frame of a source video while maintaining the original motion.
• Storyboard: Instantly transforms rough 3D mockups, blockouts, or basic prototypes into fully stylized and animated renders.
• Mask: Allows users to isolate specific subjects or regions within a video and apply selective text prompts or changes, leaving the rest of the frame untouched.
• Render: Converts untextured, raw 3D or CGI renders into hyper-realistic or stylized outputs using guiding input images.
• Customization: Unlocks higher-fidelity, specialized output by training or tailoring the model to specific video assets.

Impact on Modern Content Creation

The introduction of Gen-1 changed how pre-production and visual effects (VFX) workflows operated. By allowing creators to rapidly prototype concepts, test out different visual styles, and visualize scenes before committing to costly physical shoots or heavy rendering hours, it democratized high-end video production.
