Invasion of the Body Snatchers 4K UHD (1978)

[brian9229]

I have a very small sub-collection(Wish it could be bigger)of uhd's I actually label 'print worthy'. These are uhd's that imo genuinely look straight up like prints on my projector, and this uhd was added to that collection immediately after the first watch, I've seen it 4 times now, it's just filmic gorgeousity!!

In the screens posted earlier comparing the Arrow to the Capelight disc, it would seem as though the German disc is better. The Arrow almost consistently has Chroma splotches and macroblocks in the comparison. I don't know if the HDR to SDR could have caused this or it is actually part of the encode. I can pick up either or with only a little price difference so I'm a bit stumped.

I'm not sure I agree.

The guy’s forehead looks worse in Capelight, and the bricks in the background appear better in Arrow.

Her face doesn’t look great in Capelight either

Even when Capelight handles chroma blocking better in a shot, the grain still seems more resolved in the Arrow.

If you don't agree we can schedule a time and place

I've noticed a trend in these super grainy movies where splotches of usually reddish/magenta hues pop up in high bitrate situations. They largely seem to vanish under less competent encodes where high frequency detail blurs a bit, so maybe that's what I'm seeing here then. It does appear that the Arrow resolves more detail in most shots. Is this Chromatic Aberration then? Just a necessary evil with high bitrate encodes I suppose.

No that's not chromatic aberration, which I think was explained to you before. And I don't know what you're looking at or assessing to be these colour artefacts but the Arrow is presenting the dye clouds, the naturally occurring blobs of colour in the film grain, with greater fidelity while the Capelight is casting out chroma noise *related solely to the disc-based compression process*, being these random blocks of colour that infest the image.

Look at the very first example, the hand picking the flower. See how the thumbnail is a uniform tone on the Arrow while the Capelight's encoding mushes the lunula at the base of the nail and has weird pink blocks extending beyond that? Look at where the forefinger meets the flower, the orange colour of the petals is literally bleeding onto the finger with some orange blocks. Look at where the edge of the petal below meets the green leaf, it's literally just a bunch of orange blocks on the Capelight. That is shitty chroma compression in action and it's a trademark of Capelight's UHD encodes.

Dye clouds really are the last bastion. It's like Grain2 but more disliked than Grain1. (Please stop nuking either)

[Geoff D]

How anyone would actually prefer the digital randomness of Craplight's compression vs the more organic look of Arrow's I don't know.

I was mistaken about the chroma blocking. Didn't know about the dye clouds. I should've just let the meister respond.

I had no idea about Dye Clouds, guess you learn something new everyday. Now knowing this absolutely the arrow is better then since it preserves the original elements more faithfully. Thanks for the info Geoff always a pleasure to learn something from you

One thing that betrays the capelight being not right: look at the caps with the flower, bottom left corner. The branch is brown on the arrow whereas the capelight's encode makes it a part of the foliage and paints it green.

[cybersoga]

Arrow has the best encode.

Proven time and time again

[Jompa]

Yes. I don't remember any compression issues on my Arrow UHD when i saw it. It has 93 mbps in average bitrate.

The Arrow being better isn't just bitrate. Encode quality first, bitrate second.

Amazing how three dimensional the Arrow caps look in comparison. That extra dedication goes a long way even if it looks small at a glance. Sloppy encodes flattening things is so icky!

Even though they have the exact same HDR grade, you can see in the top right that the HDRMax values are almost consistently higher on the Arrow, presumably because it retains more high-frequency detail.

Will confirm with an HDR graph later.

[ko8ebryant24]

While they are obviously very similar, on average, the Arrow has slightly higher values. Even when the Kino's maximum value on the same frame is higher, the Arrow still maintains a higher or equivalent average (https://slow.pics/c/Qa07yBWt?canvas-...ge-fit=contain). This difference may not be noticeable, but it is noteworthy in terms of encoding quality.

[Show spoiler]

The DV metadata plots are identical.

What do you exactly mean by encode? Do you mean restoration work like do a 2/4k scan or something?
