We don't have a video link. However, you can try the BRC PositivePay file Creator - QB Desktop  and/or the BRC PositivePay file Creator - QB Online in trial mode for 30 days to see how it works for you. The trial is fully functional and there is no charge or registration needed to start the trial. Just download and install to start the trial.

I have not used the Treasury positive pay product and so don't know exactly how the tools compare. I did review their site and it appears that both tools do basically the same thing.
