Sky quantization in analog air captures

[Poutnik]

I use Huffyuv for captures.
Time by time I can see in my analog TV air captures quantization of sky luminance ( discrete gradient ).
Is it normal because of RGB<>YUV conversions ?
Or is it more probably quantitied already as TV station record ? (MPEG2-4) ?

I'd say it's in your feed.

There are probably very few conversions you are going thru. And since the color depth is already relatively low, I'd be surprized that color space conversions cause this issue. In fact, there is a color blur going 4:2:2<->4:4:4 which I would think would have the opposite effect.

Spatial smoothing or DTC compression would do this.

At least that's what I think. :)
