Video editing software designed for motion effects and versatility.

In addition to essential features like basic cut editing, animation, sound mixing, external library extensions, project management, and text editing, our software offers a wide range of powerful tools.

It also supports layer-based editing, which differs from traditional track-based editing. This approach makes it easier to apply multiple effects to individual assets, providing greater flexibility and creative control.

Installation

First, install dependencies.

npm install

and, Download ffmpeg and ffprobe into ./bin, in a folder named for the target you are building. Only the folder matching your machine is needed to run the app locally; npm run build reads whichever one it is packaging for.

bin/
  darwin-arm64/{ffmpeg,ffprobe}     Apple Silicon
  darwin-x64/{ffmpeg,ffprobe}       Intel Mac
  win32-x64/{ffmpeg.exe,ffprobe.exe}
  yt-dlp

Compatible binaries can be downloaded from https://github.com/cartesiancs/ffmpeg4nugget

The macOS builds must be native. An x86_64 binary runs on Apple Silicon through Rosetta 2 at roughly half the export speed, and nothing in the app will say so. Check with lipo -archs bin/darwin-arm64/ffmpeg, which must print arm64. The build also has to carry libx264, libx265, libvpx-vp9, prores_ks and the VideoToolbox encoders; ffmpeg -encoders lists them.

next, Permission grant is required. Please enter the command below to grant permission for bin folder.

chmod -R 777 bin

Running

npm run dev
npm run start

Releasing

npm run build:osx signs, notarizes and uploads the macOS build to a draft GitHub release. Publishing that draft runs [mirror-r2.yml](.github/workflows/mirror-r2.yml), which copies the release to Cloudflare R2 and updates the manifest the website's download button reads:

• https://download.cartesiancs.com/cartcut/latest.json: version plus the Apple Silicon and Intel .dmg URLs
• https://download.cartesiancs.com/cartcut/latest.txt: the version alone, as plain text

The GitHub release is the source of truth, and in-app auto-update still reads it. To mirror a tag that was published before the workflow existed: gh workflow run mirror-r2.yml -f tag=v0.5.3.

Roadmap

Our ultimate goal is to empower creators to produce motion graphics effortlessly. We hope they can achieve stunning motion effects without relying on heavy software like After Effects.

Please refer to the [roadmap file](./docs/ROADMAP.md) for more details.
