How does the smooth motion on/off logic work?

"only if there would be motion judder without it..." - Smooth motion is turned off on VFR video, how can madVR think there won't be judder?
"... or if the display refresh rate is an exact multiple of the movie frame rate" - Isn't this a good example of when SM is *not* needed?

i still don't see dxva2 as obviously superior but let'S leave it at this.
I meant that it's superior since it doesn't consume massive amounts of CPU when decoding large HEVC files. This is assuming MadVR doesn't hog 99% of the GPU already, but I doubt it requires more than 5% GPU power on my 1080 TI with DXVA2 Copy-back.

IIRC DXVA is done on a separate chip (or a dedicated section of logic on the main chip) so it shouldn't use the rest of the GPU (except for copying data back and forth).

Are you sure that's madVR causing the delay?
It seems like it may be either Windows SmartScreen checking, or your media player (perhaps version or other telemetry checking).
The last time I checked madVR doesn't attempt any network connection unless you have the LAN option set (which isn't impacted by internet connectivity).

Isn't madVR using a network connection to send crash reports which is the telemetry of your system?

Only if it crashes and only if you actually press the Send button. This would not interact with playback at all.

The madVR options thread should have the answers to your questions.

chroma upscaling 4:2:0 -> 4:2:2
it should not be 4:4:4?

it is doing 4:2:0 -> 4:2:2 -> 4:4:4 with "simple" scaler.
why this is the case well i guess you have to ask madshi.
doing it in 1 shader should be faster if i remember it correctly Shiandow was testing this.

madVR makes this decision at startup and will use whatever value for the frame rate it is told by LAV, it doesn't analyze timestamps.

You were right, thanks. It's strange because Focus Assist was supposedly disabled, but problem went away only after unticking all options.

Yes, focus assist seems oddly behaved. It needs to be completely disabled or it damages performance even if it is not supposed to be doing anything.

Can we get the ability to go negative (below 0) in custom video levels in madVR? For example, being able to go to -16 would fix incorrectly encoded black levels on a laptop or PC system that maps 0 to black and 255 to white.

That affects both ends though right? From my quick test it seems to. I've seen content where the peak white levels are correct, only the blacks are mis-mapped. Hence the request.

Have you tried:

If you CTRL+F for "tag" in the changelog you'll see others that may be of use.

Hi fellows,

I'm sure I am not the only one following progress over on the AVS forum....waiting patiently.

Can anyone else with a HDR set confirm at this stage that madVRhdrTestFinalColor4.zip is producing a picture with far more depth, contrast, and better tone mapping than the latest version (today)? Maybe I am misunderstanding the latest builds in terms of what it is trying to achieve - are the latest builds purely about trying to restore detail, or is Madshi, using the results of Color test builds, and now on to restore details?

Forgive me if it's a stupid question, but on a HDR set, madVRhdrTestFinalColor4.zip is producing the best image of all test HDR to SDR builds to date (100, 100, 100, 75, 50, 25, off, off)

K

Latest 3 test builds are only making changes to the detail restoration algorithm, the rest of tonemapping pipeline is not affected, as far as i know.

I think I got it now, but they are not that well explained in the options panel. Still doesn't address the VFR issue.

But doesn't LAV know about it being VFR? At least mediainfo says it's VFR, so it should be known without even looking at the timestamps?
