Introduction

🎬 Clapper is an open-source AI story visualization tool.

Clapper can interpret a screenplay and render it to storyboards, videos, voice, sound and music.

Please note however that the tool is at an early stage of development, for the moment it is not supposed to be really used by "normal" people (some features don't work, there are no tutorials etc).

Public alpha access

A public instance of Clapper is currently hosted on Hugging Face, you can try it at Clapper.app

Bounty Sponsors

Those generous sponsors are paying for code bounties:

Moon (github, twitter, website)

Want to contribute?

For users or corporations

Sponsor specific features

If you wish to sponsor the project, help attract new developers, or promote a specific feature faster, you can open a bounty for a specific ticket (eg "fix music segment duration", "add support for Adobe Premiere Pro export", "finish .fbx integration") and open-source community members will be able to submit pull requests to solve them.

I propose to use Boss.dev to do this as it has lower fees than other platforms: boss.dev

If you submit (to pay) or take on (to earn) a bounty, please post a message in the GitHub thread and/or on Discord to help everyone coordinate around it.

I am currently working to add documentation to help onboard new developers, this should help new people taking on bounties.

For developers

Licence

Clapper is under a GPL v3 licence, see the LICENCE file for more information. This is a similar licensing to apps like ComfyUI or Blender.

Installation

Prerequisites

As a prerequisite you need to have git lfs installed (see the .gitattributes file at the root of project):

git lfs install

Clapper has been tested with Node 20.15.1.

To make sure you use this version, you can use NVM to activate it:

nvm install
nvm use

If you find that Clapper is working with a more recent (stable) version of Node, or have a better version management to suggest, please open a ticket.

Installing and running the app

npm i
npm run dev

Making sure everything is working properly

There are no tests yet (I will create a ticket for that), but until then you can run the following command to make sure all the types are consistant and properly set:

npm run build

Running the app with Electron

An Electron build is in progress.

There are still some things to debug and figure out, but if you are a developer you can try it out by starting Clapper through Electron like this:

npm run electron:start

If that doesn't work for you (issue with node-gyp, setuptools, distutils etc) you might have to run:

python3 -m pip install --break-system-packages setuptools

You can also build Clapper for your operating system by typing:

npm run electron:make

You might see a DeprecationWarning message written in red at the end but that's only a warning, just open ./out/make to check if the build worked.

Code conventions

I haven't setup Prettier or a Linter yet.

Testing

@jbilcke-hf is working to add tests, and will also act as the "QA engineer".

To run all the tests (unit and e2e) please run:

npm test

This is not instantaneous: playwright may seems to do nothing for a while at first.

Unit tests

Note: I've just added Vitest so we only have like 2 tests for now.

To run the test without watching, type: npm run test:unit:ci

To run the tests with watching, type: npm run test:unit:watch

End-to-end tests

Note: I've just added Playwright, but we don't really have tests yet.

Please note that due to the app needing to build during 30~60s (depending on the speed of your computer), running those tests may take some time to execute.

npm run test:e2e

More Playwright commands: npx playwright test Runs the end-to-end tests.

npx playwright test --ui Starts the interactive UI mode.

npx playwright test --project=chromium Runs the tests only on Desktop Chrome.

npx playwright test example Runs the tests in a specific file.

npx playwright test --debug Runs the tests in debug mode.

npx playwright codegen Auto generate tests with Codegen.

We suggest that you begin by typing:

`npx playwright test`

Architecture

For convenience, you can access and inspect any of the services at runtime (in the browser's JS console) by typing useUI.getState(), useIO.getState() etc
