Make the screen scaling 5%. After rendering, the computer should automatically turn off

I made a panorama using a screen resolution higher than standard Shotcut. When zooming out to 10%, the screen was still big and I couldn’t use some filters that go beyond the screen, there are many of them. In this mode, the “size, position, rotation” filter worked very poorly for me, I can’t explain it better.
It is necessary to make the computer automatically turn off after rendering.
All time filters were glitching for me, animation keys were disabled and it was impossible to restore them. But this is better than nothing.
Not once did a window pop up about lack of RAM in Windows 10. Shortcut hung or threw an error and stopped rendering.
It is necessary to make it possible to disable the binding of interface windows, so that it would be possible to leave them anywhere.

All this can be related to my software and equipment.
