The :mod:`pygame2.sdl.video` C API contains fundamental objects and functions for accessing and manipulating the screen display, image surface objects and overlay graphics.
The PySDLSurface is the most important object type for the :mod:`pygame2.sdl.video` module. It is used to hold information about the 2D pixel buffer information of any visible object for the :mod:`pygame2.sdl` modules.
PyOverlay is a low-level overlay graphics class for :ctype:`PySDLSurface` objects. It support direct operations on the YUV overlay buffers of the graphics objects.
