There is a setting that can treat 25p as 24p using reclock or videoclock. I have tried reclock. Now I would like to try videoclock. Can someobe point where to download videoclock? I have been looking around and only reference I got is using JRiver

I would still test the GPU using stress test software just to be sure. Corruption/instability issues are not always heat related, though that's indeed the most common cause. For example, if there is a problem with one of the VRAM chips, it can go completely unnoticed until something actually tries to use that memory location. madVR is quite video memory hungry, especially in 2160p.

I just ran OCCT, didn't have any issues...

It may be something else but this is a common issue when overclocking my video RAM just a bit too much.

Your issue might be bad video RAM. madVR uses the GPU heavily, especially with high resolution content, maybe this heats up weak RAM enough to start causing errors.

edit: oops, this advice is a bit late.

Export HKEY_CURRENT_USER\Software\madshi\madVR to a reg file or alternatively give madVR access to write the bin file by giving all users permission to write files in that directory (probably ideal)

Like I said, this also happens without upscaling, so 1080p24 windowed, where I got rendering times of 10ms... before I used SVP, so madVR had to render 60 frames instead of 24, so this is now less than half the load I used to have...


also when I play the 1080p content with 2160p resolution set in 1080p windowed mode I get white pixels, but playing the exact same 1080p content with 1080p resolution set in fullscreen mode I don't get white pixels... So the GPU has about the same load and does the same thing, but only if I have 2160p resolution set, I get white pixels, no matter what kind of load is on the GPU...

I will try default settings later, I hope that will fix it, so I can start to figure out what is causing it...

Honestly, it still sounds like bad video RAM to me, not madVR interacting badly with LAV or the GPU drivers or something. Maybe some part of RAM that is only used when you are running 4K frame buffers or something. Bad video ram can result in odd problems, reproducible white spots that only show up in some games, some benchmarks, some resolutions, etc. are common symptoms of bad video ram in my experience. It doesn't sound related to heat/load in your case but do you have a few 3D games you could play in 4K to test with?

Good luck, if you do figure it out please let us know!

Nothing will BSOD. Everything should work, at least for anything other than a 480X it would seem.

Can you make a screenshot? (You can do it with PrintScreen in windowed mode.)

MAK
the driver image "enhancement" are applied when using DXVA. so check these settings.

Your question about using "mkv to 4k in HDR" does not make sense. Also your projector does not support 4k, nor does it support HDR. It's a 2008 model. It seems to have HDMI version 1.3.

For 4k support you need a 4k capable projector, at least 1.4 version HDMI and for HDR support you need HDMI 2.0(a). You also need a GPU with suitable HDMI output and enough processing power.

How are you expecting to make it work with a 8 year old projector?

ok, I just finished my madvr gpu comparison. Here are a conclusion of my observations:


RX480:

- If you guys want to go for the AMD, I would definitely wait for the custom design card. The fans of the standard cards are a bit noisy.

- The rx480 is comparable to the GTX970 in terms of power consumption, while getting a bit better performance

- had problems with jumping render queues (but no glitches or dropped/repeated frames

- couldn't get HEVC files running with dxva2 copy back enabled. Worked only with software decoding

- RX480 displays near perfect 23,976fps (1 framedrop every 6 hours)




GTX 1070:

- performance gain of 4-93 % against the RX480. In most cases it is between 20-40 % performance again while using same or even less power.

- the MSI custom design often keeps in passive fan mode. If under heavy load the fans are running, but not audible from the outside the computer case.

- playing a FullHD, HEVC 10 Bit file, the GTX hada power consumption of only 60 W and fans kept in passive mode while RX480 used 190 W with loud fan noise.

- The MSI GTX1070' dimension where to big (279 x 140 x 42 mm) for my fractal design node 605 case. So i had to get the motherboard out of the case to finish my comparison. If you like to go for a GTX 1070 while using a small htpc case, I would consider to look for a smaller card (My personal favorite is the Palit 1070 Jetstream)

-running a movie with 23,976 fps without dropped/repeated frames is only possible with a custom resolution (same as with my old GTX 970)



I am torn between the performance and the price of the GTX1070. Performance wise it would be a keeper, but the price of 479 € for the Palit Jetsteam GTX1070 is a bit high. (MSI's GTX 1070 even more; 529 €)

I'll wait for the GTX 1060 and then I'll made my decision. Hopefully I can get one and add it to this comparison.

Thank you very much for this comparison! I put in an order for the EVGA GTX 1070 for my HTPC. I've always had AMD cards for my HTPC before, but I prefer the efficiency on the GTX 1070. I was hoping for GTX 1060 reviews today but unfortunately NDA is not lifted yet. Looking at the specs 1060 vs 1070; GTX 1060 has 66.7% (1280 vs 1920) of the CUDA cores of the GTX 1070 but has only 30W less TDP (that is 80% of the 150W's of the GTX 1070), which probably means less efficiency. If the price holds true it will probably be more performance for the price though. Availability at a decent price concerns me though so that also weighed for ordering the GTX 1070.

if you are talking about HDR sample files yes madVR can play them on any display.

decoding and processing these files needs a powerful GPU and CPU if a HEVC hardware decoder isn't present.

But sometime random thing happens. For e.g. 16.3 has random flicker horizon lines (the kind like in the horror movie effect) while playing video with madvr. If it didn't appear right after installing but only after a few days/weeks i may very well, unable to troubleshoot and be annoyed to death.

it is clear, you do not understand the question.
I want to see 4K material downscaling to 1080p, but wanted to know if he can use the HDR processing of madVR (if there is information in the metadata file) and be able to view the improvements even partially.

Native Gamut is large is extensive compared to the rec 709 .. and accepts 10bit 4.4.4 signals. It can be used to view the effect HDR (partially?)
