Isn’t the video in 480p to start? Why would you need to upscale it to that?
How does it look? Are you willing to share your upscale? I would be curious to see it in 1080p or at least 720p.
Also, there was someone who made this. Apparently they upscaled it to 4K and it looks absolutely incredible: https://www.youtube.com/watch?v=O6mA1U3lUVc
