Key Features of Runway Gen-4.5

Realistic Physics and Motion

Gen-4.5 is built to respect how the physical world behaves. Heavy objects settle instead of floating, liquids pour and splash in believable ways, and handheld-style camera moves feel like they were shot on real gear rather than drawn frame by frame.
PromptGenerated Clip
A slow tracking shot glides across a kitchen table covered with fruit, glassware, and a steaming mug. Morning light spills in from a window, casting soft moving shadows on the wooden surface.

Strong Prompt Adherence

Instead of losing track of characters or actions mid-shot, Gen-4.5 keeps the main story beats in focus. It follows instructions about camera movement, staging, and mood, so crowded scenes still look organized and intentional, not random.
PromptGenerated Clip
A long continuous shot of three friends walking through a busy night market, the camera following behind them as neon signs and steam from food stalls fill the background.

Stable Characters and Details

Gen-4.5 is tuned to hold onto fine details like hairstyles, fabric texture, and facial structure as the camera moves. That makes it easier to keep a main character consistent across shots without constant re-generation or heavy cleanup.
PromptGenerated Clip
A close-up of the same young woman on a morning train, warm light hitting her face as she turns slightly toward the window. The camera tracks her small movement, capturing the passing scenery as soft reflections shift across her features.

From Photoreal to Stylized

Whether you’re aiming for footage that could pass as a real shoot or a more illustrative, stop-motion-inspired look, Gen-4.5 keeps lighting, composition, and motion coherent while switching styles, so the sequence still feels like one story.
PromptGenerated Clip
The same city street first rendered as gritty photoreal footage, then as a warm, storybook-style animation, in one smooth stylistic transition.

Top-Ranked, Creator-Ready Performance

Gen-4.5 sits at the top of independent Video Arena rankings with an Elo score in the 1,200+ range, yet it still runs at roughly the same speed as the previous generation. As the latest evolution of <a href='/video-models/runway'>Runway</a> models, it’s designed for day-to-day production work, not just polished demos.
