How to make a video of a certain size in adobe premiere?

Question

Adobe Premiere

I have a video sequence captured, in the game I have a window, let's say 200x400, so I need to capture from that video series with such a size (200x400) so that it plays in that window and, accordingly, the video itself must be of that size, that is, cut a certain rectangle from the video sequence in a certain place and make a separate video of this piece out of this, how to do this, tell me?

Answer 1

In the top menu:
Sequence > Sequence Settings
and in the window that opens, change the resolution.
