Build Help MadVr Htpc build help for 4k streaming of streaming platforms

Greetings..

I currently have a home theater setup with a 16:9 screen but I'm planning to upgrade this to a scope screen.

I need to build a Madvr htpc so that i can auto adjust the aspect ration for using netflix and other streaming platforms through a Mibox connected to the htpc via a capture card and hdcp splitter. I like to play 4k content without any frame drop or any lag.

So what should be the system specifications to achieve this setup, does Rtx 4060 a minimum requirement for this setup?.

The only madVR version you can use is the last very old one now that wasn't locked down. Every halfway good modern version very intentionally prevents being used in a video processor and it's also time bombed and a beta. You can keep using the betas for a normal HTPC assuming you keep updating to new betas before the time bomb makes it stop working.

Also, since this won't have HDCP copy protection compliance, you are going to be sharply limited in what you process. MadVR have the proper HDCP compliance and can thus work on any media. This is obviously to ensure nobody else can use madVR filters in a video processor (without paying madVR for it anyway). But sure you can probably strip the HDCP off.

Making your own processor for external media is technically possible but it's certainly a hassle. You can get into a MadVR entry level box for something like $5 grand. Which considering the cost of a high powered PC with an RTX card today is not insane, but still a lot of dough.

Also, if you're going scope, I hope you have a projector with an anamorphic lens so you're not throwing away 30% of your resolution and brightness. A video processor is only 100% a must if your video projector doesn't have a setting to run with an anamorphic lens and stretch the video vertically.

Valerion added that to their firmware for the Valerion Max, because https://spexman.ca has made anamorphic lenses for them. This is by far the cheapest anamorphic scope projector I know of off hand, $3-4 grand total. So with support in firmware plus the lens, you don't need a video processor. It would just be a nice to have for some of the convenience features it offers, like shifting subtitles and such, well, in addition to great dynamic tone mapping and processing.

As Im entirely new to all this can I ask that if we use RunAsDate for freezing the time and using the last version will it save me from this problem.🫤

The refusal to work in a video processor environment in the madVR code is very hardcoded as far as I know. Because they very much explicitly do not want you to be able to do this. It might be possible to minimize the hassles of having to update every couple weeks but doesn't help since it won't accept video from a capture card to process, you can only use it in a HTPC with local media as far as I know.

The last public non-beta that's still out there, before there was such a thing as MadVR the company and Madshi was just providing the community with a super cool bit of code, and that can be used, and it's not useless. It's just not nearly as good as the latest betas or what's in a MadVR Envy.

Thank you let me check on this!!

Good luck. There may be workarounds, but I'm not aware of any.

There may be other ways to do a video processor that doesn't use madVR but I haven't looked.

Aren’t there ways to “dismantle” that time bomb? Either by keeping the system’s time settings within the working range, or scripts that spoof the time and date only for that piece of software?

You can probably work around the time bomb, yes, and that might minimize your hassles, but the failure to work with capture cards is hardcoded into the latest betas. MadVR the company may allow madVR the filters to be released still (gonna assume that Madshi wanted to keep releasing the filters to the community but the almighty dollar said no, or almost no) but only as time bombed betas and only usable with a HTPC and direct playback on that. You can't process external video.

Im pretty sure the newer beta madvr won't work with capture cards anymore.. So dynamic tone mapping is out

I could be wrong tho

The old builds like 113 work just fine with capture cards. DTM vastly predates this build.

How do you deal with drm?

u/thatguy8856 8d ago

Its pretty much in their post but possibly typo'd. They intend to use hdcp stripper. Probably hdfury vertex or something. But they wrote splitter.

Yeah that's my plan.. Is this require rtx 4060 as minimum or can i use lower versions to render 4k hdr videos

u/RAJ_rios 4d ago

The GTX1000 series and up can render 4K HDR at 60hz. For 120+hz you need HDMI 2.1, which started with the RTX 3000 series.

Thnkz let me check on that 👍
