CelAction2D - Short Review

Design Tools



Product Overview of CelAction2D

CelAction2D is a professional 2D animation software widely recognized for its use in producing high-quality, high-volume animations for films, TV series, and commercials. Developed by CelAction, a London-based company, this software has been a cornerstone in the animation industry since its initial release in 1999.



What CelAction2D Does

CelAction2D is designed to streamline the 2D animation process, allowing animators to create smooth, realistic, and expressive animations efficiently. It does not include drawing tools; instead, it focuses on animating assets created in other software such as Adobe Photoshop, TV Paint, Illustrator, or Flash. This separation of drawing from animation enables teams to divide tasks between designers (who create the assets) and animators (who focus on posing and timing).



Key Features and Functionality



Rigging and Animation

  • CelAction2D uses a rigging system where character models are rigged into a skeleton, allowing for easy manipulation and reuse of animations. The software supports advanced Inverse Kinematics (IK) tools to pose characters accurately and efficiently.
  • The skeleton’s movement can be automatically inbetweened and deformed, making the animation process faster and more consistent.


Effects and Compositing

  • The software includes over 60 built-in effects that can be easily applied, animated, and edited within the scene. This enriches the visual quality of the animation with minimal effort.
  • CelAction2D allows for compositing different layers of the character, including adding shadows, highlights, and other effects to create a more realistic and appealing look.


Scripting and Automation

  • Version 4.1 of CelAction2D introduces significant enhancements to its bespoke scripting language. Macros can now take user input, set and manipulate variables, and use animation stored within the character rig to construct customized poses or movements. This makes it easier for animators and riggers without prior programming experience to automate tasks.


Audio and Lip-Syncing

  • The software allows for the simultaneous playback of audio samples in the exposure sheet, facilitating precise timing and lip-syncing. Audio samples can be color-coded and automatically mixed together for ease of use.


Rendering and Export

  • CelAction2D offers real-time preview of animations in low resolution, with the option to render them at any resolution, including 4K. The software supports multiple camera views and can export animations in various formats, including PAL, NTSC, and HDTV.


Integration and Compatibility

  • The software interoperates well with other industry-standard tools, allowing for seamless integration into existing production pipelines. It can import 3D CGI models and position them in a fully three-dimensional space, and even export movement data to Adobe After Effects.


User Interface and Productivity

  • CelAction2D features a user-friendly interface with dockable tool panels that support multi-monitor setups, enhancing productivity and the ability to handle complex projects. The library tool allows for the efficient storage and reuse of assets such as drawings, characters, and skeleton models.

In summary, CelAction2D is a powerful tool that combines advanced rigging, automation, and compositing capabilities with a user-friendly interface, making it an indispensable asset for animation studios and professionals aiming to produce high-quality 2D animations efficiently.
