Best place to save video files too when using iCloud

Hi,

I have a Mac and am editing with Davinci for the first time..
What is the best place to save your video files so that they don't take up space in your iCloud? iCloud only takes up to 2Tb.
I used to save them to the desktop but realised that wasn't the best idea.
Any recommendations for the best workflow?

Thanks in advance,

Richard
