Are you sure that Hotel Aremis is in HDR? I thought I'd read that it wasn't.

Edit: reading through the thread I see this was already addressed, sorry.

This was talked about a few posts ago.

Just for fun & curiosity, what's everyone's hour meter at?  I'm at 1200...

I forgot to look last time it was on, but I'm right around 1000 hours I think.

I don't understand the love for MadVR.  When you use an HTPC running MadVR you get a constant dropping of frames because video cards can't do the exact frame rate necessary for 24 fps.  It's soooo annoying.

Only because you don’t know how to set it up properly

There are a few active support threads for MadVR, highly recommended to post there to resolve your frame rate issues (provided your GPU is powerful enough for what you’re trying to do with it).

With nVidia you need to create custom refresh modes, either with MadVR or with CRU depending on the driver version. AMD GPUs used to be mostly fine from that respect but I haven’t used one for a while.

I went from a frame drop every 3mn to a frame drop every two hours, up to a few days.

Agreed, MadVR can be tricky to configure, but once it’s done there is no better source on the market today to play Bluray or UHD Bluray.

He's not getting dropped frames because the cards can't do "exact frame rate". It can and most GPUs are better at this than hardware players from the likes of Oppo and Panasonic. He's getting dropped frames because the GPU being used isn't fast enough to work with the settings being used. It's not madVR's fault.

Dylan, I think it's more the fact that movies require 23.976 frame rate but I've yet to see a video card (at least NVidia) be able to do that.  I can get mine to do 23.97531 which is close, but there will be still be dropped frames due to the rate mismatch - nothing to do with GPU.   And then even when you get your desktop frame rate close, you then play a movie that's 24.00fps and you're hosed.

There have been measurements done on Oppos and some of the other more expensive BD players. Guess what? Most of them were as good or worse than a relatively recently built GPU from nvidia or AMD.

Most of the time I'm watching a film I get this sort of performance. As you can see, with the sync rate shown, which is close to your best nuimbers seen, you only get a frame drop every 6.8 hours. A single frame drop hours after the movie would be done. So this is not the issue you're referring to:

Again, this seems more like an issue you're experiencing with render time resulting in dropped frames. This is due to a slow GPU and/or improper settings selected within madVR. What GPU do you have. Can you post a screenshot of the settings you're using? When you're using madVR next and you see dropped frames, press "alt + j". This brings up a OSD. What does the OSD say your render time is?

Well it seems now I'm actually doing well with the average movie.  I swear it wasn't this way a week ago.  I installed a new router yesterday and wondering if it's playing a role in any way.

Of course there's still a problem if the movie has a non-standard frame rate like The Fog:

I have an 8gb nVidia 1060.  PC is 4th or 5th generation i7 with 8gb RAM.   

I need to give madVR's tone mapping a shot.  While I love the convenience of a movie server (mine has 2000 HD movies and 370 UHDs) I absolutely LOVE how the UB820's HDR optimizer (in concert with my Lumagen) works.  Technically it's double tone mapping but it's the best image I've experienced.

Just tried madVR 92.17 and turned tone mapping on... it's converting to 709... I was expecting 2020.

That can be fixed by changing this setting to REC2020 (Or P3 if you want).

Oh, thanks, Dylan.  I didn't think to look under the calibration menu.

I just now saw this thread and glad I did as I got to read as things progressed with the 4500 overtime.

Love my 4500 guys and this coming Friday Dec. 14th from what I have seen in posts where some of you have had Chad B do his thing I'll be even more happy.

I looked tonight after my Single Malt / Deadpool 2 Superduper Cut Sunday !! My RS4500 is at 1074 hours.

Well, two things come to mind,

1) I hate that I've burned more hours than you given you've had yours longer.

2) It seems we have more in common than the same projector.

I average around 500 hours a year on my projectors over the last 16 years - all projectors. Pretty much just movies. But with the RS4500 it looks like my yearly average is closer to 660 hours a year.

I did do a " Kingsman " single malt tasting night a while back. I have 12 single malts. Every guest picked their own bottle. Every time someone drank on screen, we drank. Then we rotated bottles. It didn't take long for someone to say " wow - they drink a lot in this movie " ! 

My buddy brought a bottle of Kirkland brand 18 year old Highland single malt he'd picked up at Costco before coming over to watch Deadpool 2. It was very very good, and very reasonably priced ( like $40 something a bottle ). Recommended.

Mission Impossible : Fallout looked outstanding on my RS4500 ( although the movie is un-even picture wise ). The soundtrack was awesome too. Going to spin it up again for friends tomorrow.
