OpenToonz

Open-source Animation Production Software−to Develop and Create All Together

What is OpenToonz?

  • This is software for producing a 2D animation.

    It is based on the software "Toonz", which was developed by Digital Video S.p.A. in Italy, customized by Studio Ghibli, and has been used for creating its works for many years. Dwango launches this OpenToonz project, in cooperation with Digital Video and Studio Ghibli.

  • This software can be used by anyone free of charge, no matter whether the purpose of use is commercial or not.
  • This is available as an open source, so that users can modify its source code freely.
  • We aim to develop a new platform for connecting the academic research into frontline animation production.

Characteristics of OpenToonz

How it has been used in Studio Ghibli

Since the software "Toonz", which is the original version of OpenToonz, was first used for some cuts of Princess Mononoke, it has been used in the ink and paint, color design and digital composition process(*) of almost all of works of Studio Ghibli. After "Arrietty/The Secret World of Arrietty", it was customized inside the company, and evolved to become more usable according to its production style.

Functions to meet on-site needs

OpenToonz is equipped with the unique functions that have been improved repeatedly based on the opinions of production staff, including the scanning tool "GTS" specializing in animation, which was developed in Studio Ghibli. For details, see "Introduction of the functions unique to OpenToonz" written below.

Effect development kit (SDK)

Dwango newly developed SDK, a plug-in effect for image processing for OpenToonz. By using SDK, anyone can add effects to OpenToonz. Video expression researchers can receive swift feedback from on-site workers, by developing and releasing their outcomes as plug-in effects.

The effects developed by Dwango are also released

By using the plug-in effect SDK, the effects developed by Dwango's machine leaning research and development team are released. They include the effect of automatically changing picture styles by applying the deep learning technology and the effect of producing affected incident light like those in classic works before the digitization of the production environment.

  • Filming

    • Equipped with the time sheet-type interface
    • Effects can be synthesized easily with the GUI using the node tree.
    • Images can be handled with the real scale considering resolution [dpi] (units, such as millimeter, are specified)
    • It is possible to use more effects by using the plug-in.
  • Other features

    • Compatible with both raster and vector images
    • Equipped with the function for the interconversion between the sequence image of the colored binarized TGA and the OpenToonz format, to secure the compatibility with existing workflow.
