madVR - high quality video renderer (GPU assisted)

However, all of the tests are for gaming, including the one linked to in that thread. Has anyone does noise comparisons during video playback? Obviously without madVR I'd expect all the cards to be silent or quiet but with madVR that could change.

I have a problem with my new rtx 2080 ti and madVR that I use with kodi and mpc-be player with lav filters 73.1 When I play primarily 4k movies, I get stuttering when using d3d11 native or copyback but much less stuttering with dxva native or
dxva copyback but still stuttering, have any others with the new 2080 card experienced the same? with my old gtx 1080 i didn't have any stuttering at all no matter if i used d3d11 or dxva and my sttings in madVR are the same, surely the new 2080 schould be able to use the same settings in madVR

If the scene is a black screen, it is 0 nits. Otherwise, it is not accurate. I just read in another forum that the current measurements may not be 100% accurate for each scene, so stay tuned...

Couple questions on setting up custom modes.

1. I ran the optimizer and got back a list of modes. I tried the first 13 suggestions, all worked on my display but were kicked back by the gpu driver for unknown error when I tried to register them. Is this a driver issue (416.34 on 1080ti)? Can I get around this some how?


2. Also when running the optimization, does it matter if the video is maximized or not? The display is set to the 23.97 test mode, the video is 23.97 running, but mpc-hc isnt maximized. I noticed when I maxmized mpc-hc the field composition rate changed to 60hz and assumed that was correct.

It would be the same thing. The noise tests are taken when the GPU is under load. Checking a bunch of settings in madVR would also put the GPU under load.

Failed custom resolutions can relate to specific driver versions, so it is worth trying another driver. Before rolling back, I would clean the previous driver with DDU.

I think the video should be maximized for the most accurate results, but the frames would be drawn at the same frequency, either way.

Sure, staying tuned...it's 0 nits all the time...also I really don't quite grasp the nit measurement line in OSD, sometimes it says "scene xxx nits" sometimes it's "tone map to xxx nits", while "movie xxx nits" is sometimes there, sometimes not...

Maybe your GPU is getting too hot and clock speeds are being throttled? I see no other reason for rendering times to be OK for 5 minutes and then go up.

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.

Just a personal opinion, but chroma upscaling doesn't need a high precision scaler. NNEDI? Are you using a really old build?

When I run the mesurement software I do not have the percentage progession that appears but just a small flashing line ??

[SirSwede]

Hello!

I am looking to buy a Panasonic FZ800 OLED and only have an old DELL Dimension E521 to run Madvr.

I can only afford a new TV and not a new desktop as well. The current graphics card I have in the E521 is GT740. I can, maybe - if I squeeze my purse - get a new graphics card alone. The most I can put in the E521 is a Inno3D GeForce GTX 1050 Ti 1-Slot Edition HDMI DP 4GB.

Most of my material is, still, only 540p and 720p. How well - if at all - would the GTX 1050 (along with a AMD Dual Core CPU Athlon 64X2 6000+ 3.0GHz 89W and 4 GB of RAM) be able to upscale 540p and 720p content to 2160p?

Edit: As far as the RAM goes I am running Windows 7 HP and all I am doing is playing the video with MPC-HC and madVR.

Do you have "measure each frame's peak luminance" checked in MadVR's HDR section?

He said he was and obviously is because as we all know it's been removed for some time.

Also yeah, don't bother with NNEDI3 for chroma.

SirSwede you should be fine with reasonable settings on a 1050.

You don't have to check "measure each frame" to create a measurements file. The utility runs on its own.

Based on your description, the measurements file must be incomplete or corrupt. It shouldn't say both "tone map to" and "scene" because they are both meant to represent the same thing.

I would delete the existing measurements file and recreate another fresh one with DXVA2 (copy-back). I would only do this as a test as the measurements files still might not be accurate.

For recent fixes, you also might want to update to the latest test build.

I would add a little more RAM, but the GTX 1050 Ti can do the job. These are your choices. Don't bother with the cheapest Zotac version: https://us.hardware.info/reviews/750...d-temperatures

It is a Command Prompt utility, so it will only flash if you click on it. Follow the instructions here, including installing 32-bit LAV Filters: https://forum.kodi.tv/showthread.php...406#pid2750406

The measurements files may not yet be valid until the bugs are worked out, so keep that in mind before creating a bunch.

[SamuriHL]

If you're going to create measurement files, I HIGHLY recommend going to build 22 or later. Madshi fixed a pretty serious bug and the previous measurement files need to be recreated.

Yes, with build 23 OSD now shows scene nits change even with the new option "enable dynamic HDR" disabled , but measured frame stays at 0 - this is expected, I suppose?

@Warner: with build 19 it indeed was required to check the "measure peak..." for the measurment tool not to get stuck at the start... not anymore

Finally took the time to test that, and it turns out it wasn't the new tone mapping that made my rendering times shoot up (and dumb mode indeed looks terrible ), it was the new highlight recovery. With it enabled there is just no way I can play 2160p60 HDR, even bilinear downscaling drops frames! (I already have 'scale chroma separately' enabled).

@madshi Would it be technically possible to implement a 'quality/performance compromise' setting for the highlight recovery? When I check with ShowRenderSteps, that option alone takes rendering time from ~12 ms to ~22 ms (downscaling to 1080).

Thanks!

So the Inno3D GeForce GTX 1050 Ti 1-Slot Edition HDMI DP 4GB, which is the only single slot version available here in my country and that I had looked up, wouldn't work?

Single slot or half-height cards are usually quite a bit worse then full sized cards, because the tiny coolers on them are really inadequate - so either the cards perform badly, or the fans end up being really loud.
