The Render Panel
The Render panel is separated from the main StoryLiner panel, for convenience. Note that it is nevertheless possible to make it a sub-panel (see Rendering Settings in the add-on Preferences)
When pressing one of the rendering buttons, the set of images to compute is built and the StoryLiner render queue starts. 2 progress bars are displayed, one for the progression of the edit and the other one for the shots.
The process can be interupted at (almost) any time by pressing the Excape key on the keyboard. The rendering is then paused and can be either continued or canceled.
