std::shared_ptr< openshot::Frame > GetFrame(int64_t frame_number) override
This method is required for all derived classes of ClipBase, and returns a new openshot::Frame object...
A Keyframe is a collection of Point instances, which is used to vary a number or property over time.
This class shifts the pixels of an image up, down, left, or right, and can be animated with openshot:...
