'Widescreen' just takes the same darned pixels and just pulls them like an elastic band to essentially result in even lower effective resolution than 4:3Īnd both can be Interlaced at 25 or 30 FPS or Non-Interlaced at 50 or 60 FPS and a few other frame rates such as cinema's 24 FPS. Please nobody complain that this is 'too complicated' as I have already left out tons of information and cut it down to the bare essentials.īoth formats are similar and often known as SDĪspect Ratio is either 4:3 or 16:9 but a confusing aspect is that in either case the encoded resolution is identical.

Note 2: Non-Interlaced is also known as 'Progressive' often abbreviated as 'P' which is where '1080P' comes from But even that will vanish as the trend increases of 'filming' new movies on digital at 60 FPS or more. Note 1: despite the improvement that UHD offers, there is some debate about the lack of 24 FPS which is what most movies have traditionally used on real photographic film. Ultra HD is UHD often called 4K and is the next jump in resolution that the world is moving to.

Though what is Ultra HD Blu-ray? I assume it's Blu-rays bigger brother?ĮDIT: And look at that guys, we're on page 11 now. I thought the second one, while decent just wasn't as good as the first (usually the case).
