Screenshot Comparisons 4K

I know they are full sized, I always look at the full size versions of Andreas screenshots as well, but even in full size the UHD and BD caps are far better than the ones on caps-a-holic.

The UHD/BD cap comparisons on caps-a-holic are way too big on my screen. Makes the images look heavily compressed/soft/noisy.

Don't have that problem with the DVD vs BD caps on caps-a-holic, only the BD vs UHD ones.

I can't tell either. Does that mean I have to get new glasses too?

So what does that mean when I CAN actually tell a difference like in this comparison.

Yes.

That you are obviously just trolling the UHD forum (which isn't news to me btw). Because the difference in detail, more often than not with the Braveheart caps, is actually rather similar to your example, if only you would look/compare properly. (And I didn't zoom anything here.)

The braveheart UHD is much clearer. There's some nasty aliasing on the BD that isn't present in the UHD.

As for the trolling comment all I can say is F.U

and if you think those two comparisons are similar then you are obviously a fanboy.

Yeah, obviously. Because I never argued against any UHD release here, never said I prefer the BD, never used terms like gimmick HDR on Lego or Pacific Rim, wasn't one of the first to point out that Dredd, let alone the terrible Yuma, has less detail, didn't say Suspiria isn't really worth it, didn't only recently argue against the filtered Gladiator or said (even in this thread) that I prefer the BD of Bourne Legacy, didn't say that I hate the look of Fury Road. Yeah, I'm obviously a fanboy.

Depending on the similarities between the Braveheart Bklu-ray and UHD, it is possible that both are based on the same 4K scan?

I think the BD is about 10 years old (if the Sapphire release was the same through it's re-issues), so I'd imagine this is a new 4K scan.

The geometry of the image is rather different between the two so it's unlikely to be the same one. Different masters from the same scan/restoration often feature differences in framing, but the internal relationship of the image generally stays the same. However if the images look slightly skewed or warped compared to each other, that's typically indicative of a new scan, since it's caused by slight physical variances either introduced during the scanning stage or due to the use of a different film element.

Harry Potter and the Goblet of Fire

I think the additional HDR caps are more interesting with this one than the mouse-over. Both look rather soft and I won't recommend glasses if one can't see a difference detail wise here (there still is such with some though - the last one maybe being the best example).

BD (upscaled) left, UHD-BD (madVR/SDR/200 nits) right

Disclaimer as to why the UHD-BD images may appear to be too dim:

[Show spoiler]Please note that the UHD-BD shots have been converted from HDR to SDR using special techniques, which drastically compresses the dynamic range of the original image (the color bit depth has been compressed as well). The UHD-BD shots are therefore not an accurate representation of the original HDR image - dynamic range, colors (tone and intensity) and contrast should be taken with a big pinch of salt and the main focus should be on comparing details. Typically, the image will appear too dark (which is by design when the caps are done at 200 nits), may lack a certain "pop" and may at times also appear "boosted" when compared to the BD shots. The SDR conversion should still give you a good idea of the actual image of the UHD-BD though and one should also be able to at least catch a glimpse of the increased dynamic range. The BD shots have been upscaled for comparison purposes, but other than that should be accurate.

#3 1000 nits (but no matter what I do, I don't like what they did with the title)








#3 1000 nits (just because of the imo rather ugly colors @200)




#3 1000 nits


#3 1000 nits


#3 1000 nits


#3 2000 nits


#3 2000 nits




#3 3000 nits
this scene has some crazy HDR and is close to being unwatchable even @200 nits (that is especially with the close-up of his face, which I didn't include) - same goes for parts of Harry vs HWMNBN
(with the close-up, I also got some purple/pink color artifacts at his mouth, which I couldn't get rid of, but I didn't include this, since I don't know if this was only caused by the SDR conversion)














noteworthy difference here:






this scene looks noticeably better/less processed and one can also tell by the cap:










#3 1000 nits, #4 3000 nits


#3 1000 nits, #4 3000 nits


#3 1000 nits, #4 3000 nits




#3 1000 nits

That is some great work you’re doing, dude.

[cleeve]

Thank you for the comparisons, andreasy.


Looks like pretty much nonexistant improvements in detail in this one. The UHD actually looks softer to me in a few shots. I'd imagine the HDR implementation would be impressive though.

[Vangeli]

Wow, the HDR is pretty insane with the Harry Potter movies at times. I'm eager to get a considerably brighter display.

Yes, pretty much. I also didn't really expect any improvements detail wise here and was actually pleasantly surprised that there were some with Azkaban.

Anyway, the HDR alone should be worth it, if you like these movies (and have an according display). With Potter I also don't care whether it's revisionism or not - it simply looks better to my eyes and suits the movies pretty well imo.

@andreasy969: Is timecode 16.02 on Batman Begins DNR'd too?

[Bishop_99]

Great work andreasy969. It must take up a good a lot of time to get all of these screenshots, but thank you for making this such a great thread. It's truly a great way to see the differences between the BD and UHD disc. Greatly appreciate these screenshots.

Yup. One of the main offenders starts about there and reaches its climax with Alfred.





While I'm at it, here's another scene that stood out to me when watching the movie and I think hasn't been posted (in form of a cap I mean) yet:





There are also many more where I think it's a mix of lighter DNR with the image just being "too hot", but it doesn't look nice to me at any rate ... (might look better in HDR though)

I actually think I'll never watch the UHD again and will resort to the BD, even though that's a pitty sometimes - very much preferred the colors with some scenes and at times also the improved compression/reduced noise in dark areas.

Thanks, very much appretiated. It think it actually takes too much time sometimes, but I'd like to see them myself (with BD reviews I most of the time just looked at the caps), can do them, so I do it. The many caps are "my problem" and most of the time "just happen" for several reasons.
