AI video editing with Lucy — change one detail or the whole style

What Lucy is

Lucy is a family of generative models for video editing, developed by Decart. Unlike models that create a clip from scratch, Lucy works on video you have already shot and changes whatever you describe in words — no need to film it again.

The idea is simple: you upload a finished clip, say what should change, and get back a reworked version in which the motion and the framing stay natural. That makes Lucy handy for content creators and marketing teams, and for anyone who wants to quickly rework or reshape footage they already have.

In genkiki.com Lucy is available in two variants in the Video → Video mode — one for precise, targeted changes and one for a full style makeover.

Versions and capabilities in generiram

The two variants cover different jobs — pick one depending on whether you want to change a single detail or the look of the whole video.

VariantModesWhat it is for
Lucy Edit ProVideo → VideoPrecise editing from a description — changes one specific thing (clothing, an object, the setting, the lighting) and leaves everything else untouched
Lucy RestyleVideo → VideoTransforms the whole video into a new visual style (animation, painting, retro) at an affordable price

Lucy Edit Pro

The precision editor of the family. You describe exactly what should change — the colour of a piece of clothing, an object added or swapped, a different setting or lighting — and Lucy Edit Pro applies only that change, keeping the rest of the frame and the motion. It is the right pick when the clip is fine overall and you only want to fix one detail.

Lucy Restyle

Instead of a targeted change, Lucy Restyle transforms the whole video into a new style — animation, drawing, painting or a retro look — while keeping the action and the motion of the original. An affordable option when you want a completely new look for a finished clip.

What it is good for

  • Changing a detail in a finished clip — clothing, an object, the background or the lighting — without filming again.
  • Restyling video into a new look (animation, painting, retro) for social media and advertising.
  • Quick variants of the same clip with a different visual look.
  • Refreshing existing footage when reshooting is not an option.
