Hi there,
I just built the svn version and everything runs fine, but i have no option to render. It is supposed to be under the “file”-dropdown-menu, isn’t it? I don’t see any “render” button.
I had to disable avcodec for compilation, but i should be able to render images i guess…
It is in the File menu accessible from the triangle in the upper left of canvas windows. You can also right click on the canvas outside any layers to get the menu. Synfig currently has a gimp-like interface.
