Thanks for the read & I'll give it a go but a couple of Q on how this works. I keep all my UHD BD's as full folder rips and sometimes play them using the BD Menu and sometimes the direct MPLS approach. Some of these discs have seamless branching with various play lengths. Does madMeasureHDR measure then store the HDR10 meta data by a time code per M2TS and the during playback keep track of what M2TS is being used at any particular time?

Can you explain this? I am familiar with the 32-bit and 64-bit programming models, but this is new to me for video processing.

AFAIK the tool doesn’t support bd folders, as it can’t process more than one file. You need to rerip as mkv (makemkv can use your existing bd folder as a source, it might be taster than reripping the physical disc).

I would expect it just uses DirectShow to read the files, in which case it should be able to record for anything that LAV Splitter can read for you, no?

I asked, he said no plans to do so. That he didn't see the value in doing so. I tend to agree with you.

Hi,

Just a quick question. For 23,976 and 25 fps movies played in 60HZ monitor what is the safe rendering time on average and max stats?

TIA

When I asked Madshi, he didn't reply but I've just done some tests and you are correct, it looks like the tools supports index.bdmv files.

EDIT: I spoke too fast, the utility quits after a few minutes.

EDIT2: I tried again and this time it created a measurements file, but it's not taken into account, whether I drop the whole folder in MPC-BE or just the index.bdmv file. Let's wait until we hear from Madshi to know if it's supposed to be supported or not.

Try DXVA2 (copy-back) instead of D3D11.

I am trying to understand how keyboard shortcuts for the different settings work. After pressing the shortcut keys do I also have to hit F2 for the setting to apply or does it apply instantly?

Secondly, I am trying to create shortcut keys for switching between the image-doubling options so I can decide on the fly whether I want NGU anti-alias or NGU sharp. Is this possible?

I'm looking to upgrade my HTPC to add 2160p HDR support. I have two options: either replace my GT 430 with a newer full-height GPU (maybe passively cooled), or swap out the box for my old TV server box, which is much smaller and would require a half-height GPU. So I have 2 questions:

- Does anyone have any experience with the Gigabyte GTX 1050 Ti OC Low Profile 4G? Is it likely to be silent whilst doing madVR duty?
- Is there a chance of a superior madVR HTPC GPU any time soon? Like a GT 2030 or 2050? What about an AMD RX560 would that work as well?

Yeah, thanx but it didn't work (and it's veeeeery slow compared to D3D11). It's a GT 1030 (I'm at my weekend location). It won't even start measuring if "measure each frame's peak luminance" is not checked in MadVR (it's only logical?) but I assume I need to deactivate it if I want the measure file to be used?

The safe rendering time in average is your frame time (i.e. 41,7 and 40 ms in this case), but using frame time is not the best idea as sometimes you can have dropped frames if the rendering time is too close to frame time even if it doesn't go above it on average, so you should also just play a movie and watch the OSD for dropped frames.

If we take the Pascal cards as reference, the 1050s were released 6 months after the 1080, and the 1030 a full year later, so it all depends on what you mean by "any time soon"
Edit: I would go with a 1050 Ti (4 GB) rather than an RX560 for madVR. The more affordable ones of each model are about the same price.

Mostly less than that. I was playing with my HD7770 and with ~29ms of both average and max stats i can have smooth playback in almost every file. But i only tested for 5 minutes and stop. Then i started watching the last episode of Daredevil and 5 minutes into it bye bye playback. Rendering times went up like crazy. So, for me, safe rendering times is around 20ms. No dropped frames.

But its at a cost. Instead of NNEDi 32 neurons i will need to stick with 16 neurons. And the difference is huge. Believe me. Im talking about chrom upscaling. Luma upscale is fine whatever i put (since its not double). Its the same with downscale except SSIM 2D.

The keyboard shortcuts are recognized instantly but can be saved to the active profile with F2.

"image upscaling algorithm - toggle" and "image upscaling parameter - increase/decrease" may be able to do what you want. You would have to otherwise create separate profiles under "scaling" and only use NGU Sharp and Anti-Alias in those profiles and swap between them by assigning each a keyboard shortcut.

This build guide has some information on GPUs and a link to a noise test for all GTX 1050 Ti: https://www.avsforum.com/forum/26-ho...tpc-madvr.html.

In this case, your TV would be doing the tone mapping, so the metadata couldn't be used because the TV can't receive it or read it.

If it says "scene" and "movie" the measurements file is working correctly. This information wouldn't otherwise appear.

OK, I figured as much. So the measurement stage is recording 0-es for some reason?
