AI Upscale….I used to be able to view my video side-by-side with the upscaled preview for 3 seconds…this no longer works in 4150? When selecting ‘Preview’ a large screen shows up with the original video…selecting ‘Render 3 sec’ does nothing….no other options to select either. I have reinstalled the software, rebooted, still same issue. Worked fine in previous version. Any advice?
