Script has [WinError 2]

Working on downloading a script for da vinci resolve and everything has worked relatively fine until now. It is a “auto sub” maker and it reaches this error message in da vinci’s console when it is about to add the subs in. I am new to this sort of thing so if anyone needs more info then what I have said I understand and will respond with what I can but right now all I can say is that I am on windows 10 pro and da vinci 19 with powershell and ffmpegg although I have 0 idea how to use ffmpegg and I think this is what is causing my issues.

I uninstalled and installed ffmpeg and Now i do not think that is the issue I am facing. rather some other variable.
