Motion engine

Cinematic motion from a handful of stills.

This is the reason Etchly costs a fraction of generative video. Instead of paying a model to invent every second of footage, we generate a few illustrations and animate them with our own engine: depth, camera moves, reveals, characters and kinetic type.

Why stills plus motion beat per-second generation on cost

Generative video models such as Seedance, Veo, Kling and Sora bill by the generated second, typically between a few cents and about $0.75 a second through API providers in late 2026. Clips run 5–15 seconds, so a one-minute video is several generations stitched together, and any shot with a melted hand or a wrong prop has to be paid for again.

Etchly flips the math. A 60-second video usually needs around 16 illustrations at 1 credit each. Our engine supplies the movement, so the cost stays flat however long the camera lingers on a scene, and a re-render that reuses the same art is free.

  • About 16 illustrations for a 60-second video
  • Motion is rendered, not generated, so the price doesn't grow with every second of video
  • Re-renders that reuse art cost nothing

Depth, camera and parallax that feel shot, not slideshowed

Every illustration can be cut out into layers: subject, midground and background. The engine moves them at different speeds, so a slow push-in has real depth. Full-frame plates get Ken Burns-style pans and zooms timed to the narration, and cut-out characters can step forward from the scene.

Camera moves are directed per scene in the script, so a reveal lands on the exact word that calls for it and not on an arbitrary cut.

  • Multi-layer parallax from a single illustration
  • Push-ins, pans and drift timed to narration
  • Full-frame plates or cut-out subjects

Line art that draws itself, characters that talk

Line-art and engraving styles are vectorized, so the engine can etch them onto the screen stroke by stroke, the way an illustrator would. It's a signature look that generative video can't reliably produce, and it costs nothing extra.

For stories and dialogue, characters can talk with mouth movement synced to the voiceover, and on-screen titles, numbers and lists animate in with the words that trigger them.

  • Draw-on and etch animation for line art
  • Talking characters for dialogue scenes
  • Kinetic titles, numbers, lists and compare layouts

Rendered natively, about 10 seconds a minute

The engine is our own Canvas-based renderer, not a browser screen recorder. It draws every frame natively and encodes in parallel across render workers, so a 60-second 1080×1920 video renders in about ten seconds. The same engine powers the live preview in your browser, so what you scrub is what you download.

  • 1080×1920 or 1920×1080 H.264 MP4
  • Frame-accurate, word-timed animation
  • Live preview uses the same engine as the final render

When you still want true generative video

We're honest about the trade-off. If a shot needs photoreal people moving, real-world physics or live-action footage, a generative model is the right tool. For explainers, stories, countdowns, listicles, product walk-throughs and most social ads, animated illustration looks deliberate and polished, and it costs a fraction as much.

FAQ

Motion engine: questions

Is the motion AI-generated?

The illustrations are AI-generated. The motion is rendered by Etchly's engine: parallax, camera moves, draw-on line art, character animation and kinetic titles. That's why you don't pay for every second of footage.

Will viewers think it's a slideshow?

No. Layers move independently for depth, the camera is directed per scene, and reveals land on the words that trigger them. It reads as an animated, produced video.

Can I control the camera?

Yes. Each scene's motion is part of the scene plan. Adjust it directly, or describe the change in plain English, like “slow push-in on the storefront”.
