The Slomo Module
One or more Slomo modules can be added by selecting Modules | Add | Slomo. This module offers multi-channel replay and slow motion as well as clip support. It records video & audio from the selected sources to disk using very little CPU.
Right click the module to open its popup menu. The following additional menu entries are available.
Select a drive for the record buffer. Preferably each Slomo module will use a dedicated SSD as record drive, although it is possible to use a very fast PCIe SSD for multiple tasks. Data rates are high, e.g. for 720p50 video the write data rate will be 69 MB/s (1280*720*1.5*50). Keep in mind that the specified write speed for an SSD drive can drop significantly when it starts overwriting old data (when the record buffer is full) and/or due to thermal throttling.
Record Buffer Size
Select the percentage of free space on the record buffer drive to be used for recording. If the record buffer is full the old frames will be deleted when new frames are added. Also displays the corresponding recording time.
Select a drive to store clips. Preferably each Slomo module will use a dedicated SSD as clip drives, but the drive can be shared by more modules, especially if it's a fast PCIe SSD.
Clip Export Folder
Select a folder to store compressed video clips.
Option > Alpha
When Premultiplied is selected the recorded video will include the alpha channel. Note this increases disk requirements for bandwidth and capacity by 33%.
Option > Preserve Record Buffer
When checked the record buffer will not be erased at program exit but remain available for the next session.
