Nvidia just introduced a new AI upscaling tool called “RTX Video Super Resolution”. 
The new tool uses AI to improve the quality of video by removing compression artifacts and then upscaling video resolution from 1080p → 4K (in real time ?). 
It would be great if Topaz VAI can use the same technology to upscale video for better performance.
