It has never been easier to control the speed and direction of a video! The new OpenShot Library (libopenshot), is a new, powerful video editing framework, which will power the future of OpenShot Video Editor. Time re-mapping is an advanced feature, but can be controlled with a few lines of code, and a simple animation curve. Take a look at this demonstration of the Blender open movie project, Sintel. I change the speed and direction multiple times, to demonstrate the power of a time curve. Enjoy.
