Tutorial

Strength:Select the strength of the noise reduction to be done. Keep in mind that too much noise reduction might look unnatural!
Batch Size:The batch size is an optional parameter just for performance improvements and the best value depends entirely on your hardware. It controls how much tiles of an image are processed in parallel. Usually a batch size of 3 is almost always a good choice, higher values might perform a little bit better, so feel free to experiment.
