@B.H.V: Regards upscaling, i wonder how it would do with some Really Nasty, Busy Background or lot of Random Highlights like Water Drops and Stuff, or even worse Glitter and Stuff like That. Guess that would be about the Worst you could Throw at it. Anything with a Well Blurred out/ Soft Background and Clean Lines should do quite Well for Upscaling, especially if they keep working on it all the Time.
Here's a quick screen record of Topaz VEAI comparing the before and after of raking leaves. Again, not perfect but in my opinion more useable than the original file and pretty decent coming from a 1.4. In the video, it shows the two side by side at normal viewing, and then zoomed in 50% and 100%. At normal viewing, it's more than useable in my opinion. Sometimes, I use anti-moire filters to fight extreme aliasing when I shoot, but I mostly use them on my Sony RX10 IV in the HFR modes since they have more lineskipping and moire compared to the Chronos 1.4.
