You can reach Safe Network Recording Settings tab by clicking Tools > Options > Safe Network Recording.
Safe Network Recording is used for option “Use Safe Copy”. Safe Copy option is encoding to a network path in a safe way such that Ingest will encode to a local temporary folder and few seconds after the encode started it will start copying to final network location.
Metus INGEST saves the auto-split parts of the encoded video in local workstation, and in a few seconds after the encoding started, it will automatically start transferring the split files to final network location. There will be no loss of data even if the network shuts down, as the split files are cached in local workstation until transferring to network has completed successfully for each split part.
