The number of simultaneous recordings and the type of recording formats will depend

on the processing capabilities of the computer.

The interface above appears by clicking the Cog Button next to MultiCorder in the main interface.

All available capture inputs are listed within the MultiCorder window. Tick the capture inputs you wish to record and click Start.

The following options are also available:

Recording Format

AVI, MKV, MP4 and FFMPEG are available as recording options in MultiCorder.

For more information about these formats see Recording Setup.

Fault Tolerant Recordings

It is recommended that a fault tolerant recording format is selected when using MultiCorder.

This means in the event of a power outage, the recording will still be recoverable.

See Fault Tolerant Recordings for a list of options available.


Select the folder to place the video files. This will need to be a fast storage device as listed above under the system requirements.
The more cameras that are recorded simultaneously, the greater chance of dropped frames if the storage device is unable to keep up.


Select and audio source to include with each recording. This can either be the embedded audio in the capture source, or Master to record the main audio mix.

New File Every

Split the recording into a new file every x Minutes.
