The Most Powerful AI Tool You’re Not Using
Perfect character consistency is finally here with AI
Hey —
If you’re using Runway Gen-4 and you’re not using the Reference Image feature…
You’re missing the most powerful tool in AI video right now.
Here’s what it actually does:
You upload a reference image, and Runway uses it to guide everything—
Style. Subjects. Layout. Camera angles. Mood. Even character identity.
It lets you:
Paste a character from one image into any scene, perfectly stylized
Keep subjects consistent across multiple clips and angles
Merge characters into new worlds while keeping them realistic
Build scenes that feel like they’re from the same film, not scattered clips
Lock in a visual “language” that AI would normally forget in seconds
Why this matters:
Most creators are still prompting blindly—hoping for something close to what they imagined.
This feature flips that. It gives you control.
It’s how you go from random generations to cinematic worlds and repeatable characters.
I’ve been using it to anchor entire visual flows, and the results are wild—true consistency across scenes, shots, and even lighting styles.
This is part of a project I’ve been working on quietly—here’s a quick look:

Talk soon,
