-Time synchronization automatically copies your host machine's date and time settings over to the guest machine's hardware real-time clock. Synchronization is performed every time the guest operating system reads the hardware clock, which often happens once on every boot.
+Time synchronization automatically copies your host machine's date and time settings over to the guest machine's hardware real-time clock. Synchronization is performed every time the guest operating system reads the hardware clock to calibrate its own internal clock, which usually happens once on every boot.
 
 * **Disabled:** do not perform time synchronization.
 * **Enabled (local time):** synchronize the time in your host machine's configured timezone. Use this option when running a guest operating system which stores local time in the hardware clock, such as DOS or Windows.

+Video
+=====
+
+The *Video* page contains settings related to the emulated machine's 2D and 3D video cards.
+
+Video⁠
+------
+
+Video card to emulate. Only video cards supported by the machine's expansion buses will be listed.
+
+The *Configure* button opens a new window with settings specific to the selected video card, such as the amount of installed video memory.
+
+Voodoo Graphics
+---------------
+
+Emulate a **3Dfx Voodoo** or **Voodoo 2** 3D accelerator, connected to the PCI bus and to the video card selected above.
+
+The *Configure* button provides the following settings:
+
+Voodoo type
+^^^^^^^^^^^
+
+Type of Voodoo card to emulate. The following choices are available:
+
+* **Voodoo Graphics:** the original Voodoo model, with a single Texture Mapping Unit operating at 50 MHz.
+* **Obsidian SB50 + Amethyst:** a variant of the Voodoo Graphics, equipped with a second Texture Mapping Unit like the Voodoo 2.
+* **Voodoo 2:** the second Voodoo model, with two Texture Mapping Units operating at 90 MHz, as well as SLI support.
+
+Framebuffer memory size / Texture memory size
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Amount of video memory to give the Frame Buffer Interface and Texture Mapping Unit(s), respectively.
+
+Bilinear filtering
+^^^^^^^^^^^^^^^^^^
+
+Apply bilinear filtering to smooth out textures displayed on screen.
+
+Screen Filter
+^^^^^^^^^^^^^
+
+Apply a filter to make the picture resemble the digital-to-analog converter output of a real Voodoo card.
+
+Render threads
+^^^^^^^^^^^^^^
+
+Allows the Voodoo workload to be split into multiple threads. 2 render threads are recommended for host systems with more than 2 CPU cores.
+
+SLI
+^^^
+
+Add a second Voodoo 2 card to the system, connected to the first one through Scan Line Interleave (SLI).
+
+Recompiler
+^^^^^^^^^^
+
+Enable the Voodoo recompiler for faster emulation.
+
+.. note:: A host CPU with SSE2 support is required for the recompiler. SSE2 is present in most CPUs made since 2005.
