Is there any way to upscale local files permanently using Nvidia's RT VSR?

I'm currently working on a volunteer project to help fix the existing lecture recordings, as well as upcoming ones at my Uni. The obvious problems are the usual - crappy audio and crappy video.

I focus on Math, so a clear, readable whiteboard is super important to me in lecture recordings, which often doesn't happen because not all professors are good with recording equipment.

I used RT VSR while streaming one such lecture and I noticed that the text on the board was far more readable. Not perfect by any means, but a much better experience than before.

I can't just tell every student to go get a computer with a 30/40 series GPU in it if they want to enjoy a readable whiteboard in a crappy recording, so I was thinking of just upscaling the recording file itself.

Normal upscaling would require a ton of computational time that the Uni isn't willing to dedicate resources to, given the scale at which videos are uploaded daily across the Uni, plus the backlog, but maybe with RT VSR, upscaling the files could work more efficiently even if I just throw my own GPU at it for the Maths lectures and re-upload them to our platform?

I don't know the specifics but I have seen workarounds on GitHub to make RT VSR work with local files in MPC-HC and such, so maybe there is a way I don't know about to do that?

Any help would be appreciated in this project!
