Plasma Studio is a multimedia handling application that features video editing capabilities, raw photo editing, vector graphics, animations, audio editing, recording and streaming, and 3D modeling. It is fully hardware accelerated, implements up to 16bit surfaces, and it is implemented via a QML libstudio library that can be used by any application to offer the same features. It allows to work via a node-based workflow, what-you-see-is-what-you-get editing, or through a code view.
