Questions, answered
What is Runway Gen-4?
Gen-4 and Gen-4.5 are Runway's flagship AI video models, known for cinematic image-to-video with consistent characters and scenes. On Ronana you can use them alongside Runway's Aleph video editing model and Act-Two motion capture, all in the same studio as Seedance, Veo, Kling, and the rest of the lineup.
How do you use Runway Gen-4?
Open Ronana's studio, choose Gen-4 or Gen-4.5 as your model, and write a prompt. Add a reference image to drive image-to-video, pick your settings, then generate. The clip lands in your library to download or upscale. No install required.
Do I need a Runway subscription to use Gen-4?
No. On Ronana, Runway's models run through Runway's official API and bill from your Ronana credit balance, so you don't need a separate Runway plan or account. One set of credits covers Gen-4, Aleph, Act-Two, and every other model on the platform.
Is Runway Gen-4 free?
A Ronana account is free and the in-browser upscaler is free, but Gen-4 video generation runs on credits. Every plan includes a monthly credit grant that works across all models. See the pricing page for details.
How much does Runway Gen-4 cost?
Gen-4 is billed from your shared Ronana credit balance; longer and higher-resolution clips use more credits, and Gen-4.5 prices differently from Gen-4. Choose a plan on the pricing page; you can cancel anytime.
What resolution does Runway Gen-4 support?
Gen-4 and Gen-4.5 generate at 720p on Ronana, with several aspect ratios. Generated clips can be sharpened to HD with the free in-browser upscaler after generation.
Can Runway Gen-4 use reference images?
Yes. Gen-4 is an image-to-video model at heart: it animates from a reference image, keeping characters and scene details consistent. Runway's Aleph model on Ronana goes further, editing an existing video from a text instruction.
How long can Runway Gen-4 videos be?
Gen-4 generates clips of 5 or 10 seconds. Pick the duration in the studio before generating.
How does Runway Gen-4 compare to Seedance, and Veo?
Gen-4 is one of several leading video models on Ronana, alongside Seedance 2, Google Veo, Kling, Vidu, and Wan. You can switch between them in the same studio and use whichever suits a shot. Gen-4 stands out for consistent characters and controllable image-to-video. Shared credits work across all of them.
