Synfig Studio

Synfig Studio is a free and open-source platform designed for creating 2D animated videos. It offers a timeline-based interface that allows users to create animations using vector graphics.

One of its notable features is the bone system, which enables the creation of natural movement in animations, similar to what is available in OpenToonz. Users can animate their cutouts using bitmap images or vector artwork. Additionally, Synfig Studio provides the Skeleton Distortion layer, allowing for complex deformations in bitmap artwork.

With Synfig Studio, animators have access to a powerful set of tools for creating captivating 2D animations. The open-source nature of the software makes it easily accessible for users, while its timeline-based workflow streamlines the animation process. Whether you're working with bitmap images or vector artwork, Synfig Studio offers the flexibility to bring your animations to life with smooth and natural movement.
