madVR - high quality video renderer (GPU assisted)

[rack04]

I'm getting some weird colors and blue horizontal lines in windowed mode. The issues go away when I'm in fullscreen mode. It doesn't seem specific to the downscaling code. Probably related to zoom control in madVR.

Seems to me you are mixing up bit depth and bitrate?

You are right
Thanks

I always used Catmull-Rom for downscaling till now; I switched to Bicubic 150 as it looks sharper without overblowing the edges and retains the performance demands.
SSIM is way to sharp and aliased to my taste; turning LL with SSIM makes it mellower (strangely, in reverse to every other downscaling algo).

I check a downscaling algo with a small/tiny window to see how much the edges and detail is effected.

Yeah, after double checking it seems some of the texture formats I'm using are not a good match. That didn't show with the test images I used.

Should be fixed in the next build.

Madshi would you consider allowing the upscaling enhancements to be controlled individually for either every 2x upscale or after upscaling?

Regarding edge thinning, I find it only really works well (with less bowing) when it's done after upscaling is complete at a high value (I use 4.0 for low resolution anime)
And it actually stacks up vs Avisynth's awarpsharp2+NNEDI3 exceptionally well when using it like that with a touch of extra sharpness. Would it be possible to allow for a 5.0 value here?

My recommendation would be to always use edge thinning after upscaling is complete, would you agree that having a higher value max value and perhaps locking in as a final stage only setting would be best by default?
I can't see where multiple thinning stages at lower values would be beneficial over one higher power line thinning pass. Ideally we want the least possible warping of the final image.

[Backflash]

Two days reporting no crashes so far. Everything else seems to be working as well for me.

So I'm using the latets LAV nightly, Latest madVR and I'm having a 3d issue.

Everything switches correctly to 3d on my projector. The stats correctly show:

D3D11 fullscreen windowed (3D)
NV12, 8bit, 4:2:0 (3D)

However it is frozen and the queues look empty. Nothing plays.
I'm using MPC-BE 64 bit, LAV 64 bit. Also tried 32 bits and same issue. I end up killing the player using task manager

Interestingly the stats say:

Composition rate: 47.951. Even though the movie is 23.976
Also vsync says: 20.85

I created a custom profile for 3D where I left the display modes blank so madVR can do the right thing. I even tried the opposite and forced the display mode to 1080p23, I had the same issue of freezinf even though everythign switches correctly to 3d. The composition rate might be the cause..what do you guys suggest? Thanks for any help.

[ShadyCrab]

If this info would be present in the bitstream, than it would also be coming from upstream LAV, and not leave madVR having to get it from the bitstream itself. Sounds like a bug in madVR to me. A sample video that shows this problem will be required, however.

Using the newest LAV nightly, madvr 0.90.4 and the latest MPC-HC nightly, I haven't been able to repeat this issue. Using a file that had this problem 1/3 the time no longer reports .609 primaries even after relaunching the file for over 20 times. Same result with related files (only the Matrix info embedded, not primaries data). Would say it seems to have been fixed.

[AngelGraves13]

madshi, what are your thoughts on Weston Three Field Deinterlacing (w3fdif)?

LAV Nightly added it a few nights ago and I've been testing it out a bit. It's less prone to presentation glitches and looks pretty good, though it can cause some unwanted ringing. It does however work great with mixed telecine content.

[Light001]

So far i have learned alot, but as i learn i also find new challenges. i decided to use try Dxva2 for Image upscaling and downscaling as i read it also does the chroma upscaling aswell for videos that it processes. Works good! and looks pretty darn good too.

For movies it does not process i chose JINC because it just seems easiest to configure and also looks very nice. i did try Nnedi3 with 128 neruons but the movie did not even start, and my graphics driver crashed , sooo im guessing either i had a different setting conflicting or ya...just dident like me. I use Cuvid in LAV with hw deinterlacing 50/60 mode and high processing. ( i have a gtx 980 with current driver)

Now, I also tried to set up reclock, and mostly left things on default, because following the ezoden tutorial (which also confused me :( so i may have done it wrong) would make the movie play and id have like music and background sound with no dialog. I use analog for audio, like the green jack in the back of my PC Mobo, and realtek hd audio is the driver.

My biggest issue currently is Audio,So like i watch movies with or without reclock at it seems with the settings im using, that the audio is just a tad to slow, like hardly noticeable..but i still feel its there. Is there a way to tell if im right or going nuts?

here are links to my stats ( i could only get windowed mode :(, i use puush for the shots, is there another easy way?stats are relatively the same in full screen)

When using nnedi3 to double 720p for a 1080p TV, what's more important, using nnedi3 in chroma upscaling or nnedi3 in chroma doubling? Or are they both a (relative) waste?

I'd say go with Reconstruction soft or Jinc AR. NNEDI3 is overkill for Chroma in most situations IMO. Better off using that performance towards something that's actually noticeable, YMMV.

Ok, for all those of you who have new problems with v0.90.x which you didn't have in v0.89.19, here's a collection of test builds which are all intermediate steps between v0.89.19 and v0.90.x:

http://madshi.net/zzz - builds.rar

Some notes for optimal testing:

1) These are all 32bit builds, so please use a 32bit media player. You can switch builds simply by replacing the "madVR.ax" file. No need to uninstall/install madVR.
2) Please don't use any of the new features of v0.90.x. Make sure you have them all deactivated (e.g. all the 3D options/checkboxes, chroma "Reconstruction" etc).
3) Please make sure you have 3D deactivated in the OS settings (only applies if you have a 3D capable display).
4) Build 1 is the most likely to still show the problem. Build 10 is the least likely to still show the problem.
5) In order to save time, I'd suggest to start with build 5. If the problem occurs with build 5, it will also occur with builds 1-4. In that case try build 7 or 8. If the problem does not occur with build 5, then it will also not occur with builds 6-10. In that case try build 2 or 3. Etc... This way you should be able to find the exact build which introduced the problem pretty quickly.

Thanks!

OpenCL build 3 solves the crash problem I was having. I repeated the same fast switch Overlay <-> FSE which caused it to crash on v0.90.x builds and it didn't crash or cause any other issue.

Stop using the ANGLE D3D11 device for H/W decoding on Windows 8+

Merging to M48

It looks like there are bugs in some GPU drivers like nvidia which causes the D3D11 context
state to get messed up when accessed from multiple threads. This inspite of us following the documented
way of accessing the context from multiple threads by enabling multi threaded mode.

This change reverts back to the old model of creating a D3D11 device per decoder instance. The ANGLE device
continues to be used for D3D9 based decoding on Windows 7, which will kick in if D3D11 is not available on that
platform.

Posting this for awareness. I know madshi did a test build of madVR confirming multithreaded DX11 crashes and it seems the chrome team noticed the same behavior as an nvidia driver bug.

Your settings sound terrible for the GPU you have. Did you try the MPC tutorial in my signature? There is no need to use DXVA2 image scaling when better options are available. And you should be using DXVA2 copy-back in LAV Video as opposed to the outdated CUVID.

[Warner306]

I tried to add to my wiki today with a section about madVR's 3D support, but I think I got more confused than anything. I don't own any 3D content and don't plan to in the near future.

The part on 3D formats is in this section: http://forum.kodi.tv/showthread.php?tid=209596&pid=1843555#pid1843555.

Could someone with better knowledge read it and tell me if this is accurate?

I am confused if madVR only supports top-and-bottom frame-packed 3D and is changing the output according to your selection. Or if this selection is about matching the source input so the correct format is output.

Something strange I noticed when using madVR. If I start a movie in 23.976Hz, 10-Bit FSE mode then I pause the video and let the monitor go in to standby mode, after waking it up the picture freezes (it also looks very pixelated) and only sound continues playing.
If I go out of FSE mode and back in again it continues as normal.
I'm thinking the monitor not initializing correctly by itself after a standby when running in this mode? And only restores itself to 10-Bit mode after triggering it manually?

Anyone else noticed this behavior?

Hi,

I have an Intel NUC - skylake (NUC6i5syk). I have this video 4K sample I was testing

http://hdrsamples.com/life-of-pi-4k-uhd-hdr-sample-footage/

Even if I set the the scaling algorithms to the most basic - bilinear...I still get dropped frames.

I thought the new intel NUC's could play 4K....Am I missing something?

Didn't have time to test different settings yet. Will try to mess around with it.

Maybe with DXVA they can.
If you are using LAV filters for example make sure you enable it in the video filter settings. Also enable 4K option in there. It should be already enabled by default in latest version though.

This kind of devices is not ideal for madVR because their iGPU are very low.
However it should work with bilinear at least.
What about DVXA upscaling?
Does it work without madVR?
Do you use Windows 10? It is maybe a background system upgrade?
What's your CPU and GPU usage?

@foozoor I'm usign windows 10 and latest everything with drivers. Also tried DVXA upscaling still dropped frames.

I tried with EVR renderer and also dropped frames...so it's not madVR fault. Just surprised the new skylake NUC has issue with that clip :(

Skylake Intel only do 8bit hevc, I remember the life of pi sample is 10bit.
So not much you can do about it.

Sent from my 306SH

[huhn]

this sample is 10 bit the intel hardware decoder is hybrid for 10 bit so it can't play 10 bit HEVC at high bit rates. hybrid also means madVR has to share the i GPU with the decoder.

only the nvidia 960 and 950 can deal with hevc main10.
all new upcoming GPU should be able too.

a skylake NUC is not a good choice for UHD.

Can someone tell me what happens when I play a full side-by-side (3840 x 1080) source with madVR when side-by-side is selected? Is it downconverted to half-SbS?

What about a frame-packed 3D source? If I choose side-by-side, is the output half-SbS or full SbS when sent to an active 3D display capable of showing full SbS?

madVR does not currently have any special handling for SBS encoded videos, so nothing happens, it just outputs Full SBS in some manner, because thats how the video looks to it.

The only new 3D format support is H.264 MVC in MKV's as of now.

Ok, so my remaining question is what happens when I select side-by-side or top-and-bottom as the format? Does madVR downconvert all inputs or does it maintain the full resolution when the source if frame-packed?

I am asking whether the output is full SbS or half SbS when this output format is selected.

[huhn]

a 1080p screen doesn't have a enough pixel to do full resolution SBS.

At the moment madVR handles side-by-side and top-bottom videos like any other 2D video. If your output is set to 1920x1080 you will lose half the resolution. Press ctrl+j to see the madVR statistics.

@Warner, However id appreciate input from the community!

Oh cool man! i was able to get Nnedi128 going after looking through your guide, i also switched to Dxva Copyback. Is there an acceptable amount of dropped frames? i have around 12 i think. i typically get them when i click for fullscreen and back to windowed. It uses 80%! of my Gtx 980!, And now, i was setting up the Scaling algorithms, and as of right now i have
Chroma Up - NNEDI3 - 128 neurons
Image Down - SSIM
Image Doubling - And this is what i was going to ask you about to make sure it sounded right, I have all the box's Checked off, and they are set to (Always If Upscaling is needed) and all of them are NNEDI3 128, and that brings up Gpu Usage to 95%. In Fullscreen i get 52Ms rendering, and in windowed i get 15ms. Hmm and it seems when in use i have alot of dropped frames. They do not constantly rise up, but between moving around in windows and going back to the show they have risen.
Image Upscaling is Jinc.
Im trying to figure out what the heck deinterlacing is and what option i should use, i have smooth motion on always, and 16 buffer, and how many video frames shall be presented in advance.
Error Diffusion - option 1
Um i turned on "use Separate device for presentation" What should i look for when turning this on and off ? is it worth anything.
All deinterlacing is turned off in "Unchecked in the MADVR" And in LAV i have everything Auto on top left, Output Formats are all defualt, and RGB is set to PC and Dithering mode is Random Atm (SHould i switch this?)
Dxva2 Copy-Back for Hardware Accel with just Hevc and UHD unchecked,
And software Deinterlacing is not checked off.

Ok soooo with those, things, any reccomendations? some days i like to just listen to videos in the background while playing video games, so i will probably just switch it to VMR7 or some nonsense in the output,when i do that because 80% Gpu usage will definatly cause issues for my gaming.

**Update
So i changed things down to 64 neurons, and i gained about 20ms rendering time bringing it to 30 roughly, and alot more stable frames, like no frame drops during regular playback so far, and thats with a Star trek TNG episode being brought up in scaling. and gpu usage is @ 70%. and cpu seems low the entire time. So i was advised also that Reclock will not make playback smoother and eliminate motion judder, and to use internal audio renderer. So thats what i am doing, aswell i still am searching for an answer to Motion judder because my BENQXl2420T, does not seem to naturally support any refresh rate (Hz) Below 60. And id rather not make a custom resolution unless advised with info, because it says it will void warranty. So i still get motion judder, and seems to be a little hmm i dunno what the term is for this , but say on a darker image its like you see a patchy pixelated blob thats not as dark as the image, a little of this not much, just a little haha and only in some scene if im looking for it.

SBS is about displaying both frames side by side so yes that's how it works.

I think the output is the same as frame-packed. The display splits the full SbS frames and shows them sequentially.

- What are your scaling factors? NNEDI3 is only useful if the image is upscaled -- at least 720p -> 1080p or 540p -> 1080p. Anything less does not require image doubling. Remember, you are doubling the image resolution. You don't want to overscale anything beyond your display's native resolution. You are trying to match the source resolution to the resolution of your monitor.

- Dropped frames are only an issue during playback. Bringing up menus and navigation can cause frame drops, but they aren't important. If the frame counter is not increasing during playback, your settings are fine.

- Deinterlacing is necessary for interlaced sources. Most sources these days are not interlaced. Exceptions are DVDs and live TV broadcast at 1080i. Only these sources would be deinterlaced. Set madVR to auto and it should take care of this for you. It will only deinterlace sources that need deinterlacing.

- LAV Video does not control dithering or RGB modes -- madVR takes care of this. The only setting to be concerned with in LAV Video is hardware acceleration.

- General settings such as "use a separate device for presentation" are only necessary if you are having playback issues. Using fullscreen exclusive mode is the safest route. You shouldn't notice any difference during playback.

- If your display does not support any resolution below 60 Hz, I would set it to the highest resolution and use smooth motion instead. Smooth motion can improve the fluidity of playback but is usually a matter of taste. You may prefer turning it off and living with 3:2 pulldown instead. I have one display that doesn't support 1080p24 and 3:2 pulldown isn't that bad.

What he said.

I've only researched this topic. I don't have any 3D content, but I've read that full SbS on a 1080p display is possible.

[XTrojan]

I've only researched this topic. I don't have any 3D content, but I've read that full SbS on a 1080p display is possible.

It's kinda not, Frame-Packed is what you're looking for.

Full-SBS is rendering 2D at left and MVC at right, the TV will then combine these two into a 3D image, but lose half the vertical resolution by doing so.

I'm not sure how MadVR handles Full-SBS but by the look of it, you need a UHD TV as it will put two 1080p video streams together, in order to do this you need a 2160p TV or downscaling is needed. I'm as well not sure if MadVR does any upscaling, it shouldn't as it's two separate video streams (2160p total). The PC can't detect the 3D, it simply detects it as 2D or well two 2D videos, the TV will then do "post-processing 3D merging". By this logic MadVR/The PC thinks the video is 4k, it's the TV who post-processes (merging) = half vertical res lost.

The PC does however detect frame-packed, frame-packed seems to be a "link" with the PC and TV while SBS is TV "post-processing" but requiring higher specs (4k 3D TV).

SBS is very similar to passive 3D, the reason Active 3D still exists today is because it saves the full res while passive 3D is half vertical res. Even though active 3D has a higher chance of causing eye fatigue(shutter glasses blinking 120times a second with black frames), major crosstalk issues, not to mention it being expensive and more annoying to set up.

I think the output is the same as frame-packed. The display splits the full SbS frames and shows them sequentially.

not at all.

frame packing 3D is full resolution by sending 2 picture with full 1080p resolution.

if it is sending 48 frames or a 3840x1080p image doesn't matter. and i don't know.
SBS is sending a 2d imaging which is the resolution of your screen.
on a 1080p screen it is 1080p on a UHD screen it is 2160p and both picture on this frame.

my TV can't do SBS at UHD resolution. i is only using 3d at 1080p and all other option are grey out. so frame packing is the only way to get full resolution for me.

- What are your scaling factors? NNEDI3 is only useful if the image is upscaled -- at least 720p -> 1080p or 540p -> 1080p. Anything less does not require image doubling. Remember, you are doubling the image resolution. You don't want to overscale anything beyond your display's native resolution. You are trying to match the source resolution to the resolution of your monitor.

- Dropped frames are only an issue during playback. Bringing up menus and navigation can cause frame drops, but they aren't important. If the frame counter is not increasing during playback, your settings are fine.

- Deinterlacing is necessary for interlaced sources. Most sources these days are not interlaced. Exceptions are DVDs and live TV broadcast at 1080i. Only these sources would be deinterlaced. Set madVR to auto and it should take care of this for you. It will only deinterlace sources that need deinterlacing.

- LAV Video does not control dithering or RGB modes -- madVR takes care of this. The only setting to be concerned with in LAV Video is hardware acceleration.

- General settings such as "use a separate device for presentation" are only necessary if you are having playback issues. Using fullscreen exclusive mode is the safest route. You shouldn't notice any difference during playback.

- If your display does not support any resolution below 60 Hz, I would set it to the highest resolution and use smooth motion instead. Smooth motion can improve the fluidity of playback but is usually a matter of taste. You may prefer turning it off and living with 3:2 pulldown instead. I have one display that doesn't support 1080p24 and 3:2 pulldown isn't that bad.

Well my star trek movie files are 720 width and 496 height. and i do have others like this. ok so leave deinterlace on auto, should i touch and nvidia control panel settings? noise reduction and the other 1, . and basically try smooth motion off and on and see which i like more?

Set everything in the control to "Application" or "Media Player" to avoid altering the image in unwanted ways. madVR should handle these things.
