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.

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.

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.

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.

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.

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.

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.

Gen-4 generates clips of 5 or 10 seconds. Pick the duration in the studio before generating.

Gen-4 is one of several leading video models on Ronana, alongside Seedance 2, Google Veo, Sora 2, 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.
