Movie Maker

just a thought, I have two web cams for weather. Would it work if I fired up a second copy of movie maker and had it take the second camera video would it make a separate movie or would it screw things up?

that will not work
there is no facility to use a second set of time stamped images as the source

There’s always MovieSalsa that can do what you want.

I suppose, but having it all in the same program , it doesn’t eat up resources. However, I will keep that product in mind. thank you ( only 59 days and who is counting to the end of the year.)
