Leonardo AI is an image-first generative platform that offers video through a selection of models, while Runway is a video-first platform built around its own Gen models and editing tools. For motion work, Runway is the more direct video tool, and Leonardo is better for building and styling stills you then animate. Styleframe (styleframe.ai) is not a replacement for either: it complements them inside an After Effects or Nuke workflow when you need keyframe-level control over the result.

Leonardo AI

Leonardo AI is a generative platform centered on image creation, with custom model training, editing, upscaling, and a motion feature that turns images into short clips. It differs from Runway in that its video side draws on a model picker (one comparison lists Google Veo 3.1 and Sora 2, plus community-trained styles) rather than a single in-house video engine. Pick it if your starting point is concept art, style frames, or branded imagery and video is a secondary step.

Runway

Runway is an AI creative suite built mainly for video, with text-to-video, image-to-video, in-context editing, and a node-based workflow builder. It differs from Leonardo in that its Gen model line (Gen-3, Gen-4, Gen-4 Turbo, and Gen-4.5 in one review) shares a consistent look, and it ships video-specific tools like Motion Brush, video inpainting, and a timeline. Pick it if moving footage is the main deliverable and you want longer, more coherent shots from a single platform.

How They Differ for Motion Work

Clip length and resolution

One comparison puts a single Runway Gen-4 generation at roughly 18 seconds at 720p, with an Extend option and a built-in upscaler that reaches 4K for extra credits. The same source puts Leonardo's Motion clips at about four to five seconds, with resolution depending on the model; Veo 3.1 inside Leonardo is described as native 1080p with synced audio. These figures change as both products update, so check current limits before planning a shot list.

Consistency across shots

Runway's single model family makes it easier to cut shots together without regrading, since the clips share a look. Leonardo's flexibility is useful for exploring styles, but each engine interprets prompts differently, so matching a sequence takes more test runs. If you are building a multi-shot piece that has to hold together, that difference matters more than any single clip's quality.

Style control and customization

Leonardo's strongest argument is custom model training. If you need a repeatable illustrative or brand style across hundreds of stills, it gives you more to work with than Runway does. Runway counters with workflow tooling: its node-based builder lets you chain generative steps into repeatable pipelines, which suits teams producing video at volume.

Free access

One comparison notes that Leonardo's free plan includes 150 daily tokens, while Runway's free access relies on one-time credits. For casual testing, Leonardo's daily refresh makes it easier to experiment over several days before committing.

Which Should You Choose?

Choose Runway when the output is video that needs to play as a continuous shot, when you want built-in editing like inpainting and Motion Brush, or when you need a direct route to 4K. Choose Leonardo when you are developing look and style first, training a custom model, or generating key art you will animate elsewhere.

Many artists will use both. Leonardo can produce a consistent set of style frames, and Runway can animate them. Neither tool gives you frame-accurate direction of what happens between two defined poses, which is where motion designers usually have to step in manually.

Where Styleframe Fits

Styleframe is built for the part of the pipeline these two tools leave loosely controlled. Instead of prompting and hoping, you drive generations with reference images, video clips, and keyframes, so the motion between your start and end frames follows your design. A typical setup is to create style frames in Leonardo or another image tool, use them as references in Styleframe, and bring the result into After Effects or Nuke as an image sequence. The compositing stays in your existing pipeline.

Styleframe also covers adjacent tasks such as reference-driven style transfer, background removal, and 4K upscaling, so it can take over pieces of the cleanup work you would otherwise send back through a generator. It does not replace Runway's text-to-video or Leonardo's image training; it gives you a more controlled route when a shot has to match a storyboard.

Final Take

Leonardo AI and Runway answer different questions. Leonardo is the better fit for image generation, custom style models, and exploring looks across multiple video engines, while Runway is the stronger choice for dedicated video generation, longer clips, and integrated editing. If you are a motion designer or compositor, decide first whether your bottleneck is style development or shot generation, pick the tool that matches, and plan to finish the work in After Effects, Premiere Pro, or Nuke, where you keep the control that matters.
