Star Trek: Deep Space 9 S01 AI Upscale 4K (2020) project, commonly known as Project Defiant
The documentary What We Left Behind (2019) provided a glimpse of what a studio-led 4K remaster could look like by rescanning specific film sequences. Fan projects in 2020 used these professionally remastered clips as a "base" to further upscale to 4K, proving that AI could achieve sharp results with both live-action and CGI.
: Documented on ExtremeTech , this project completed its run in May 2020. It focused on using Topaz Video Enhance AI to combat the "blurry" look of the original digital effects.
