hi madshi , The authors of SRCNN have published another paper about accelerating SRCNN(FSRCNN).now it can run in real-time performance

is super sampling active?

For those with performance issues:
First reset the settings. That will undo all silly performance killing changes that you may have made, like supersampling.

Press Ctrl+J to display the OSD. Look at the details that are shown and first check if the algorithms that are used match with what you expect.

You can show extra details by creating an empty folder called ShowRenderSteps in the installation folder of MadVR.

Post a screenshot if you need help.

old news and it largely advantage anime related stuff, since waifu2x is based on the normal srcnn. For irl content it produces way less impressive results.

There is also ESCPN or VESCPN specifically designed for video upscaling. But there are either patent issues or knowledge issues on madashis site, so an implementation is very unlikely.

If you look for an very good upscaler (albeit a specialized one) than there is enhancenet https://arxiv.org/abs/1612.07919 , which might be feasible in the future. But now it is not realtime

Tried resetting everything to default but performance was even worse lol. And there are no sillyerformance killing changes in my profiles :-)

The weird thing is, for me, when the queues just drop, pausing the video and letting the queues refill and then unpausing it fixes it (until the next time they drop). If i dont pause and then unpause the queues stay empty and continues dropping gazillions of frames infinitely (well ok to the end of the video). I've even made changes so that render times stay between 10-15ms so lots of headroom. So i'm stumped.

are you running out of Vram? check the advanced rendersteps part and see if you get spikes in finalstep.

Sounds like GPU is overheating.

when i turn on Exclusive Mode and exit i noticed madvr reset my calibration setting in the system
even when i set [disable calibration controls for this display] on and [disable GPU gamma ramps] off
sorry for my english

I find my self prefering NGU-AA 50% of the time and NGU-soft the remaining 50% of the time.

Even running a torture test heat doesn't pass 70. I'll check advanced render steps a bit later, hopefully that will give more of a clue

If you are running out of VRAM, try with minimum queues. Could easily check that with GPU-Z running same time as watching.

Could be your GPU downclocking then...not sure.

this works for me thanks.
i never know theres differences between adaptive and optimal performance.

Hey, I just found out this week end that to be able to use the HDR metadata passthru with MPC-HC, I have to use the 32bit version. I have always used the 64bit... this might have been tell before in this thread and I've misse it probably...
anyway since the switch, I have been able to test out both the Nvidia API as well as the Windows 10 API and both work pretty well. On one occasion the HDR flag stayed up after exiting the movie and I couln't find any way to reset it exept rebooting my PC. But overall , works nicely.

When playing a source video in DXVA2 copy-back mode with BT.2020 matrix & primaries and passthrough HDR, Mad-VR says "HDR 1000 nits, BT.2020 -> DCI-P3".

Should I select DCI or BT.2020 in my TV (X850C) menu settings? With BT.2020 enabled the colors look deeper without oversaturation.

Is there a setting in MadVR to disable the BT.2020 -> DCI-P3 conversion (DXVA2 native mode, perhaps?)

Thanks for any help!

This line only informs you of the actual used colorspace inside the stream. Its always contained in a BT.2020 container, however BT.2020 covers a huge range of colors which isn't fully used by anything so far (nor can TVs fully reproduce it). So HDR contains metadata that informs the player about the actually used colorspace - in this case thats DCI-P3, in a BT.2020 container.

So that line is just informationl.

You should select whatever you set in madVR under devices -> <device> -> calibration. Those settings have to match (if you're not calibrating manually, set it to display is already calibrated and select BT.2020 or DCI-P3 in the box below)
At this point in time, perhaps using DCI-P3 would be best, although BT.2020 would also work (but if you're not using 10-bit output, it may cause a bit of loss).

Are my colors wrong?

Hey there,

I encountered this pack containing some test videos and some of them caught my interesting: https://drive.google.com/file/d/0B9F...p1eGVnTG8/edit

When I play "MP4-2c\Basic Settings\3-White Clipping.mp4" what I see on the screen matches what the video says: 235 and higher are completely white, while 230-234 are slightly gray (refer to the image), but shouldn't I see whole range up to 253?
I tried checking colors in Paint and 230 column is actually 249 white, while 234 column is 254 white. Why is this considered to be correct output when colors are incorrect?
Similar issue with "1-Black Clipping.mp4" file - dark colors are darker than the number says.

On a properly calibrated screen and playback chain, you should not see values above 235 or below 16.
Note that when you take a screenshot of the video, it is already after various levels of processing, and the values don't match the actual values in the video.
