One or more Replay modules can be added by selecting Modules | Add | Replay. The module stores all frames in memory and is therefore very fast, but make sure you have enough memory available. For 640*480 @ 30 fps you need about 800 MB available RAM. The formula to get the memory requirement per replay module in MB is
vertical resolution * horizontal resolution * frames per second * 3 * 30 / 1000000.
If there's not enough memory available, the module will be disabled and you cannot select a video source. Due to limitations in 32 bit software, the max. amount of memory available for VidBlasterX, and so the replay modules, is 4 GB.
A description of all controls, commands and options is listed below (right click the module to get access to its popup menu).
