The Replay Module
One or more Replay modules can be added by selecting Modules | Add | Replay. This module offers basic replay capability by offering the ability to scroll back 30 seconds in time. 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.
