Rat Sniping ... This guys ATN 4k Pro video is QUITE Excellent.

ATN 4K scopes, recording in just 1080p, that is such a mind scrambler for me, not least as i am a a somewhat knowing person know that there are true 4K sensors that will do just fine in such a scope. ( i have one of those in a 4K PTZ camera )

The SOCs to support such a sensor are also there in spades.

Anyways nice target rich environment

They use 4K sensors, and that allows a 2x punch in with no quality loss, and another 2x with negligible loss, hence the 3-14x scope has worse quality on at 14x then at 10x.

Yeah Steve Allan mentions this in his comparison between it and the Pard 008
 
Digital zoom is, by definition, always lossy.

Not quite.

Since the video you are getting is always 1080p, a 4K sensor is only giving you 50% of the available resolution, or in other words it is downscaled for certain magnifications. On the 3-14x, you have a 4K downscaled image at 3x (highest quality), a 1080p crop out of a 4K image at 6x (no quality lost for 1080p output), an upscaled 720p image at 12x (quality is degraded), and a slightly more degraded image at 14x. At max extended magnification of 36.8x an image roughly 360p is presented.

I do video production as a side gig to pay for all my pew, pew goodies. 😀
 
I wasn't talking about post production editing. When you use digital zoom in a camera or scope, the resolution gets worse because you are not optically magnifying the object/subject, you are simply viewing/"magnifying" a smaller area of the sensor. So, you actually are using less pixels to create the image no matter what the resolution of the screen on which you are viewing it.

You are completely wrong.

It's not the resolution of the screen, as ATN scopes don't have 1080p screens, it's the resolution of the video recording output.

I highlighted from the ATN page in crayon so it's more clear. 

If they used an 8K sensor instead of 4K, they'd be able to make a 3-28x scope with the same quality as the current scope, they'd just spend more processing power down scaling the image using typically bilinear or nearest neighbor algorithms.

I hope this helps the explanation, as I'm not good at breaking things down I do daily with other electrical engineers. I'll try to find one of those good YouTube videos they use to break down technology, kinda like the How It's Made TV show.
 
I think you are missing my point. When you use digital zoom as opposed to optical zoom, you lose resolution, therefor it is lossy. Less information being used to fill the viewing screen. It doesn't really matter what the sensor or display resolution is. This effect is obvious in the videos and pictures where digital zoom is used.

I think this concept is just above your head. I will try and explain is once again, but it will take you opening your mind to something that you are not familiar with, instead of sticking to the digital zoom is lossy belief. So let's start with, digital zoom is lossy, and I will prove you right in this circumstance.

If you take a 1920x1080 sensor and produce a 1920x1080 video, then zoom 2x while still creating a 1920x1080 output video, this is a form of lossy zoom. Pixels will be duplicated or dithered (producing a false pixel through a math equation, that is in between the two original pixels).

But if you start with a 3864x2218 sensor and do a downscale of the original sensor resolution to 1920x1080 for a 1920x1080 video, this has no loss is quality. Now zoom into it 2x, a 2x zoom is the same as dividing the original resolution by half. That leaves a 1932x1109 resolution which is still greater than the 1920x1080 video you are producing, so you have no loss in quality.

This is my last comment on how digital zooms work. Hopefully this was educational to some, and just a rehash to others.

Enjoy! 😀
