I've read your post several times, Phoenix, and I'm still not clear what you're asking. (Maybe I'm just dense.)

What is it you're trying to save time doing?

It sounds like you might be talking about rear projection -- an old movie technique in which a movie is projected from behind on a semi-transparent sheet so that the person in front of it seems to be standing on a street in Paris, for instance, instead of in a movie studio.

Is that it?

If so, that's possible but it's also a process that even Hollywood has long abandoned, for a number of reasons. Green screening and C Chroma Key are much simpler and, with today's technology, so much more effective.

While recording a video, for streaming,
I have a video clip running that will show by use of chroma key as a background
Total effect similar to a news broadcast where background is a moving picture
What I am trying to figure out is
can I pause that background momentarily during the recording?
Then, restart it...
Sort of like a slideshow in the background... Intel i5-9400F / B 360M MB (MS-7B19) 2.9 Ghz /

What you can do is freeze tje video at the desired moments.
Move to the point you want the video to freeze.
Make sure that that point is "selected" showing the red line on the right spot.
Right click the mouse with the pointer in de video clip
Select Edit video in the menu

Sounds good.
Will try to do it that way.
Thank you.
