Synfig Studio puts powerful 2D animation at your fingertips, allowing you to create film-quality animation right from your desktop in minimal time.
It uses a combination of bitmap and vector graphics to achieve professional-quality animations that all skill levels can produce. It fully supports numerous layer types such as geometric, gradients, filters, distortions, transformations, and fractal. You can also create cutout animation via bitmap and have full vector artwork control. Another nice feature to add that professional touch is that Synfig Studio supports basic sound syncing your newly created animation up to a soundtrack using the Sound Layer.
The basic goal with Synfig Studio is to eliminate the need to draw individual frames (frame-by-frame animation) to achieve movement allowing you to dramatically cut down the time needed for creation and the need for other outside resources.
