Salvageable video that only recorded on left side of screen?

[Leonakitty]

Hey there! So, I recently bought a 49" monitor and never thought to check settings before recording a video. After the event was over and a day later I went to edit the video clips I noticed they are all like I only recorded the left half of my screen. Since then I have adjusted my settings to record the entire screen but in the mean time, is there any possible way to adjust those video clips to show the other half of the screen? Or are they all trash now? I have saved them in hopes that anyone may know how to adjust so they will show the whole picture.

That part of the screen has not been recorded. It's not part of the video, so it's gone.
