JVC RS1000 / 2000 Anticipation Thread

[Dylan Seeger]

@avsmike hi, USB firmware updates? that would be great, even more than 4k supports

I've seen a few people laugh at this feature being touted as an upgrade. All I'll say is that this is a new platform for JVC and I wouldn't be surprised at all if we see several firmware updates over the next year for these new native 4K models. Having a USB-A port will be extremely handy. RS-232 is just a pain in the you know what to use. Most people don't own PC's with a 9 pin RS-232 port which forces people to use USB adapters and most of us here know about the variability in compatibility these adapters have.

Pre - order pricing for the new JVC's ends this Sunday the 14th - you have been warned !

I just noticed this write up of a pre-production review of the N5 (RS1000) on a German website:

I already knew from previous tests that this lens is very sharp down to the corners. But now it has to prove with discrete 4K resolution and therefore more than four times as many pixels. And that made it good.

Sure, it does not quite reach the quality of the mega lens of the already tested big brother JVC DLA-NX9B, but it comes amazingly close and up to the corners painted all eight million pixels as clear, tiny squares. Only with strong lens shift, the sharpness to the edge of the lenses naturally lessened slightly. Thus on test pictures even scripts with only a few pixel resolution could be read crystal clear.

It looked damn sharp at Cedia.

About 72 hours left to get a new JVC at pre - order prices !

[AVSCraig]

Only about 48 hours left to pre - order a new JVC. Email us over the weekend to get on the list !

Preorder will be extended until projectors ship to us.

Just when I thought I had successfully resisted the siren song of pre-order pricing in the name of patient resolve... Someone better lash me to the mast until we have passed those sirens calling from the shore!

I've seen a few measurements taken from the N9 over the past few weeks. JVC must be giving them strict guidelines on what can be made public knowledge. Out of the 3 or 4 pre-production write ups I've seen, I'm only seeing color gamut coverage CIE charts given out. No word on calibrated lumen output, contrast or any other type of objective measurements. The NX9 can do 103% of the P3 color gamut, but at what cost to light output? I surely hope it's not actually the 20-30% reduction in lumen output talked about at CEDIA and IFA.

Are there even any finished production units with finalized firmware available to measure ? I doubt it.

[Dylan Seeger]

Firmware is one thing, but the native performance of the light engine should be relatively close to what the production units are going to be. Unless major hardware changes have been made since the pre-production units were manufactured then I highly doubt we'd see a big difference in lumen output and contrast compared to a finalized production model.

I agree. I would have loved for JVC to set a limit of 15% light loss and whatever the DCI coverage came to be, let that be the number. I don't care if it does not reach 100%. I would much rather have 98% and only 15% light loss vs 103% and 30% light loss. Too much light loss and it becomes unusable. I tried to explain this to JVC, but not sure the factory gets it. We will have to see where this ends up. If it is 103% and 20%, I can live with that, but if it is 30%, I doubt I use the filter.

[Dylan Seeger]

The odd thing is that I thought JVC's engineers understood that given the eshift models got to about 99-100% of the P3 gamut. It seems they were doing just that; more saturation with minimal light loss. A 10-15% loss of lumen output is/was acceptable to most to gain color saturation. I doubt most people will use the filter if a 25-30% drop in brightness happens. After all, HDR is about specular highlights and cutting off 25%+ of your usable brightness doesn't make much sense to me whereas the ~10% light loss seemed like an acceptable trade off. So I don't know if this is about bragging rights (so on paper it's better than what Sony offers) or if they're doing it for some other reason.

Hi Dylan,

There is at least one other reason I can think of, which is to make sure that it’s always possible to cover 100% of P3 for all units at all times. Some units have an undersaturated gamut from day one (most often due to a wrong hue for a too yellow green, which makes all the points between green and blue (including cyan) undersaturated at 100% sat. I think this is why THX uses the filter even for rec709. Other units are fine when new, but can get undersaturated at 100% sat over time. Nothing that a good calibration can’t take care of for the most part (as there is little to no actual content between 90% and 100% sat), but still annoying if you are after absolute color accuracy.

So yes, getting 100% with the filter and 90% without is fine if all units can achieve this and if that remains the case over time, but it’s not really okay if you end up with 80% without the filter and only 90% with it. Some can’t even reach 100% of rec-709 without the filter after a few thousand hours!

So I know this isn’t a popular stance but I for one applaud JVC’s decision to extend gamut cover with the filter enabled, if a stronger brightness loss with the filter translates into a proportional increase in gamut cover. If we lose 30% to get 103% of gamut cover instead of a 10% loss to get 97% (as in the current eshift models), then of course I agree it doesn’t make much sense. We’ll see!

According to Ricky, the native gamut on the new models doesn’t reach P3 red anymore without the filter, so that might explain some of the additional light loss if it’s not only a green filter.

Another reason is that there are more and more UHD Bluray titles reported as being mastered to BT2020 (including films, possibly because they were mastered to be shown in Dolby Vision for the cinema which is BT2020, not DCI-P3), so if there is indeed content above P3 in these titles (which remains to be seen), then it makes sense to slowly get towards the actual standard, which is BT2020... by 2020.
