GridIron Software has released X-Factor, an Adobe After Effects Professional v6.5 extension which speeds preview and rendering capabilities by using grid computing technology. Users install the software across multiple computers on a network, and X-Factor helps to process previews and rendering in the background - so After Effects Pro can continue to work while the processing is being done.

The Basic edition of X-Factor is bundled with After Effects Pro v6.5, and enables two additional computers to work - you can also download a Mac or Windows installer from the X-Factor Web site. X-Factor Plus scales to more computers and is available for $99 (around £55) per CPU. GridIron also offers X-Factor Unlimited, which can be used on an unlimited number of additional computers, for $1,995 (£1,100).
