ok thanks for your help

I've thought about moving my PC to my media room and running it as an HTPC with MadVR, but I just don't know much about how it works. I built the PC myself in 2015 and changed the original GTX 970 with a GTX 1070 when it came out (thought about changing to an RTX card so I could play Quake 2 with Ray Tracing in 1080p, lol). Anyways, I'm sure there is a thread that teaches about MadVR.

Question: can MadVR add HDR highlights to 1080p discs?

No, 1080p video format only outputs SDR. MadVR wouldn’t have any HDR highlights to play with. But that’s okay. MadVR will upscale 1080p to 4K, if you have a 4K video device and give you the best picture possible (IMO). So those 1080p videos will have never looked so good. I have a 1070 Nvidia GPU and am real happy with performance. My next PC will have a 2080ti to take advantage of upcoming MadVR PC improvements and let me run all MadVR performance options at their highest levels. That's the plan anyway.

Good deal! I saw a comparison of Interstellar on UHD vs Interstellar on Blu-ray upscaled with MadVR. The results, minus HDR, were very similar. Maybe I will my PC from my office to the HT room and play around with it.

I don't know much about madvr either but I'm interested as well. My understanding is you have to burn the movie into the pc before u can watch it.. how long does it take to burn a movie.. And for streaming you can only use custom curves correct?

30-60 minutes depending on your BD drive and total data or the disc. I have 2x BD drives, so I can open multiple makeMKV instances and run an extended back up session. I have the storage to back up complete directories and then make smaller .mkv files.

Yes, most will rip movie to hard drive (AFAIK). Select, Windows based media players are required for playback. I don't use custom curves since I output SDR2020 from MadVR. Not to hijack this thread, the best thing one can do is search out threads specific to MadVR usage. “VERY” in-depth stuff for non-technical people, with high learning curve. I’m a retired programmer, so this is just same old, same old to me. You’ll see why so many are excited about the upcoming MadVR-Envy VP. Most would probably be happier not having to deal with a Windows PC in the HT environment.

It’s a common misconception that the movie must be captured to the HDD to play through madVR.

It’s also possible to play a movie on a disc in madVR without ripping, with some other software on the HTPC.

You need the same disc drive capable of ripping the movie to the HDD and also a software called RedFox AnyDVD HD which performs the real-time decryption of the disc.

With AnyDVD HD running you are able to open the disc video in a madVR capable video player without first ripping it.

It has to do with reference point. With DTM, the bar has been raised.

Would sure like to see a shoot-out between DTM on JVC, Lumagen, MadVR-Envy, and any other contenders.

In celebration of all of our friends test driving the new JVC software, I did a double feature last night:

Blade Runner -The Final Cut and 2049, both in 4kHDR.

Settings:

UB820
Optimizer ON
+6 dynamic range
+1 brightness

X990
BT2020
7500k (Alt - High Bright - Red Gain -5 - Green Gain -20)
JVC Gamma B (dark level +5)
Contrast = +8
Brightness = 0
Low Lamp
Manual Iris = 0
Clear Black = Low
Enhance +2

To my eshift buds, give the JVC Gamma B a test drive. Bump up its dark level adjustment. See what you think this choice does for image dynamics and color.

lol, same Tom.

I used to (still would if time would allow) love to build PC's. I look at the price of Radiance Pro and ask 'why would i go that route for tone mapping?' The answer, lack of time ATM...

I would need to research the suitable components for HTPC to run MadVR and after the build is complete figure out how to tweak MadVR to work correctly with my setup. I can only imagine significant time investment to do it right...

The only problem with MadVR, other than having to build and set up the PC, is, it is only a solution for HDR DTM for disc. Does nothing for streaming content. That is why people are looking at solutions like MadVR Envy or Lumagen.

Actually, @Onkyoman guide is so good that anyone with minimal computer skills can easily design and mount an HTPC with madVR in a few hours:

I Googled MadVR Envoy and didn't come up with a good descriptor. What is it?

Those fimilar with Sony pro cameras and their "look", that's the best way I can describe the affect of JVC Gamma B curve manipulation... looks like a Sony camera lut. However, Gamma B is a little too dark compared to 2.4, so I set B's dark level to +5, excellent low end dialed in.

I know it gets old to say, even irrelevant according to some, but I love the visual experience of this setup. Maybe it is lacking the high light performance refinement seen with some DTM options, but the rest of the image and lower end dynamics entertain these eyes.

I use your settings on Page 1 on my x790. Should I alter them with those above? I do not have a 4K player as I rent discs and never purchase them.

Jack, no. These are for SDR/2020 from the ub820. For any normal SDR HD sources, stay with the 1st post info.

You can experiment with the JVC Gamma B option and High Bright option, but the other changes will not track well.

As I have only owned my 540 for 7 months or so, I find I have already changed Manual Iris from -6 to -3 (to compensate for aging bulb brightness?) I have @ 150 hours on PJ. I’m wondering if all the other JVC picture settings need to be addressed as well. Seems like too much work. Maybe an Autocal would be in order soon? Never tried DIY (meter driven) video calibration before. Yikes! What could go wrong?…famous last words.

Are you using high bulb?

So far I have measured 0 drop in my NX5 after 175 hours in low bulb.

And it uses the same bulb as your 540.

All viewing in Low bulb. But my hours are 225 not 150, just checked tonight.

Once you suffer the initial lumen drop in the lamp, the decay rate is reduced and lumen drop & color shift are more stable.

If you have never done an AutoCal, running it to resolve any gamma droop, is a worthy endeavor. At 150 hours, you're in the range where the lamp is stabilizing, such that the AutoCal session would require a long period of time before re-calibrating.

If you would be calibrating a projector for the 1st time, the Manni JVC cal thread is a good resource.

You might also consider investing in a visit from one of the numerous calibration professionals among our members.

I had quite a bit of experience calibrating my own displays in the studio and my previous Sony SDR projectors. However, given the degree of nuance with HDR, put the responsibility in the hands of someone with far greater HDR experience and JVC eshift experience, was a no brainer.
Tom Riddle and catav like this.

Variant to try... Test on Ready Player One 4kHDR

UB820
Optimizer = ON
Dynamic Luminance = +8
Brightness = +1
Dark Tone = 0 to +3 (adjust dark detail to taste)

X990
Color Profile - BT2020
Color Temp - High Bright - (Red Gain -5) - (Green Gain -20)
Gamma - JVC Gamma B (adjust dark level = +5)
Contrast = +2
Brightness = +2
Low Lamp
Manual Iris = 0
Clear Black = Low
Enhance +2

There is definitely an advantage to bringing the projector master contrast back to test pattern specs and pushing the ub820 dynamic luminance range up a few clicks instead.

The ub820 has so much range to allow the projector to be left dialed into test pattern setups, and just use the dynamic range to achieve realistic daylight scenes.

I looked at this a bit last night Neo. Have to agree; @Onkyoman has done a very nice job with this guide; and thank you for recommending it!

Nice guide, @Onkyoman ! This makes me want to build another PC! Maybe I should just get over it and take my PC out of my office and run some MadVR. I would probably need to change the case from the tower.

It has to do with reference point. With DTM, the bar has been raised.
DTM is the next chapter, but are there compelling differences between the current DTM solutions?

While it's still early in the feedback phase of the new JVC DTM software update, some of that feedback suggests the new DTM feature set controls lack the nuance and/or granularity, of the madVR or Radiance Pro alternatives.

So for me it begs the question, will the JVC DTM controls have the flexibility for owners to change/adjust parameters for some of the Low, Mid, High presets? For instance, if on a scale of 0 - +12, Low = +3, Mid = +6 and High = +9, what can be done if High = +11 would have been a better parameter setting option?

The ub820/9000 have Low, Mid and High dynamic range presets, but the user can over ride those presets and manually adjust anywhere along the -12 - +12 dynamic luminance adjustment range.

This not to say the available controls within the JVC DTM feature won't be a good upgrade over static ATM, albeit less flexible than the alternative DTM solutions.
