All the while not understanding that projecting a video of unknown resolution onto a large screen in the courtroom could have the same effect as zooming the image.
- MillenialMan 5y agoThat's not really true. Video upscaling is probably going to be linear interpolation, which is very unlikely to add meaningful artifacts, but an intelligent zoom that tries to add visually meaningful information may change the apparent content.
- paulgb 5y ago> Video upscaling is probably going to be linear interpolation This is probably true of the technology that's currently in the courtroom, but not for much longer, e.g.[1]. Apple have even done research on this[2], although I can't find anything that says it's currently in use on the iPhone/iPad.

- Krisjohn 5y agoSeeing the mess my 4k "smart" TV makes of 1080p video with parallax scrolling (say a car driving between two rows of trees, filmed from the side), I think we're well past linear interpolation in consumer devices with upscaling.
- boole1854 5y agoCounterpoint: projecting a video onto a large screen is just well-understood optical physics whereas the iOS "video up-scaling function" is a black box.
