I can't begin to list the 500 to 1000 dollar models. Since you want to edit video how about the one my son has? It's the Asus at link.

It's currently a little over 1K but has ranged in price from 980 to 1100.

There is no laptop I know that edits video well and gets more than a few hours on battery. You have to pick power or battery time.

I think it's much lighter than our older model Asus which was 7.3 pounds.
This one is 5.6 pounds.
