About the comment on laptop video, that is not 100% true. Some higher end laptops do have more advanced video (such as Macbook pros there are others including some Windows ones), but yes many lower end laptops don’t and adding that to an existing one isn’t going to happen.
I don’t know the OP’s software, but one thing that might help him is to try editing in quarter res if the software supports that.
