Create/insert a software sim that is smaller than stage size?

[Guest]

I have an existing project that is 960 x 720. I want to create a software simulation whose capture size is 800 x 450 and then insert it into my existing 960 x 720 project, centered on the slide. How can I do that?

On my blog you can find an old post "Create and use a Knockout Master slide" I did not test the work flow on the latest version however.  Have a look at:
