Building a video editor around the way designers already work

Composa is built on a simple belief: the skills designers use in Figma or slides should carry over to video editing.

The problem

Moving a design into video usually means starting over

Two things break when designers move into video. Their Figma or slide-making skills no longer map to the editor, and the design itself becomes a flat asset without its original layers or controls.

The product

If you can use Figma or make slides, you can make video

Composa keeps the canvas and property controls designers already know, then adds the timelines and media tools needed for video.

01 · Compose

Design on a canvas you know

Paste a design from Figma, then arrange its layers with the same canvas controls, layout models, and property panel designers expect from a design tool.

02 · Add media

Put video and audio on one timeline

Import video and audio, then place them on separate tracks under one playhead.

03 · Animate

Animate like it’s Keynote

Start with Build in, Action, and Build out, then use the motion gizmo, keyframe diamonds, easing, and property controls to refine the result.

Key decisions for V1

What makes V1 lovable?

The first version was centered on one flow: paste a design from Figma, add video and audio, animate it, and export one video.

  1. 1
    Keep the design mental modelThe canvas, layers, property controls, and motion presets should feel familiar before someone learns anything new.
  2. 2
    Prove one complete loopFigma-to-video parity is the direction. V1 earns it by making the design, media, motion, and export loop coherent end to end.

Competitive research

A video-first canvas can compete across creative workflows

I looked beyond traditional video editors to tools for animation, asset creation, explainers, and text-based editing. The opportunity is to bring those jobs into one editable canvas and timeline, building from the familiar motion model already in V1.

Competitive audit and market opportunity
These references point to four ways Composa could expand: familiar presets for animating objects, asset generation within the canvas and timeline, screen capture with annotations and voiceovers, and text-based edits connected to video. Together, they suggest a video editor that supports more of the creative work around a finished video.

Designing media for V1

A video editor needs more than a timeline

The canvas and timeline established the editing model, but a credible video editor also needs media and audio effects. I used Sequence as a reference and translated its controls into Composa’s design system.

Media effects

Translate the useful controls from the reference into a system that belongs beside Composa’s canvas properties.

Audio effects

Give audio the same legible, direct-manipulation model as the rest of the editor.

Where it stands

Shipped and available in public beta

Composa is live in public beta for you to try. I intend to launch publicly soon and track signals on how it’s received as I decide whether to keep growing it as a side project or turn it into an open-core, founder-led business.

Reflection

What I learned

Building Composa taught me to put a working product in front of people to test the opportunity, and how to build production-scale software efficiently with AI workflows.

Build to validate

I saw a gap between design and video, then built a public product people could try. The strongest signal comes from putting the idea in front of the market.

Work faster and more efficiently with AI

I learned to give AI agents clear tasks, test their work, and review changes before shipping. Turning that into a repeatable process helped me move faster between design and code while staying responsible for the product.
