Nice work making (and open sourcing) a notebook for Real-ESRGAN certainly will lower the barrier to entry for folks. I'd suggest adding some screenshots in the README and maybe make mention of how it compares with other options / tools.

Thanks, I'll improve the README with screenshots & more description soon!

Would be great if you could share TL;DR with how it works and other details

Real-ESRGAN addresses the challenge of blind super-resolution, aiming to improve the quality of blurry or pixelated images that have undergone unknown and complex degradations. I made a minimal notebook that can upscale videos to 4k on free google colab using Real-ESRGAN!
