Hey, Benjamin.
That doesn’t look too too bad. Why not try to get creative and work with the mistake instead of trying to fix it?
Maybe slap a Gaussian blur on there. Or try to focus eyeballs on the speaker’s face (rather than the distracting wall) by adding a vignette.
I have a plugin called “FilmStyles” (I paid maybe $50 for it and got a dozen or so effects), and I have used the “35 mm DOF” effect to add a slight blur around the edges of an image (you can choose how big/shape the blur). There’s also an effect called simply “FilmStyles” that allows the option of adding a soft glow to the entire image; that effect is often helpful for softening mistakes. https://filmstyles.dvcreators.net
Just a thought. Make lemons out of lemonade.
