The Replay Module
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, light on CPU usage, but does require additional memory (up to 5.6 GB for full HD @ 30 fps). 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.
Right click the module to open its popup menu. The following additional menu entries are available.
Set the delay in seconds.
