This feature request has been brought up multiple times, we're all aware of the limitations of some sets and the likelihood we'll see anything addressing those in madVR in the short term. Didn't really need it brought up again, by the time anything is likely implemented you'll have a new TV.

I recently added a new graphics card to my computer, a RX 5700 XT on PCIE3x8, in parallel with my older Radeon R9 290X on PCIE3x4. Both work fine with madVR except with the 5700 card it takes an additional 2 seconds to start video playback compared to the old card with exactly the same madVR settings. Seems unrelated to the file being played. I assumed this was shader cache related and tried clearing that from Radeon settings but nothing changed. I enabled "delay playback start until render queue is full" to avoid dropping frames at the start for now but would rather remove the delay.
Start time from when MPC-HC window appears to video playing: On display connected to R9 290X: 1.3s On display connected to RX 5700 XT: 3.1s OS Windows 7 64-bit Any ideas what could be causing it and how I could fix it? I also seem to have been hit by coil whine with NGU (very high is very noticeable, others are slightly audible) but can almost completely (only audible if room is quiet or ear next to computer) resolve that by setting "don't flush after intermediate render steps". Combined with lowering GPU powerlimit to -50% (still plenty of performance left) it completely removes the coil whine (barely audible with ear next to GPU). |

2015/2016 Oleds had terrible near-black gradation. I've had a LG C6 before and that TV would show any near-black artifacts exaggerated. Recent Oleds generally handle near-blacks much better but there are still some issues... |

if an screen is unable to display this properly is just an completely different issue. what so ever this file is not nice. deband high does a pretty good job on it but this is not fixable is just how much do you want to hide vs how much damage to the not dark part are fine to you. it's could be possible to trigger the dreaded black makro block flickering on these LG oleds: https://www.youtube.com/watch?v=Sl_t3UQ3gAk mastering screen are usually IPS 1000:1 screen like the eizo coloredge series there are other screen that are not IPS yes there are but that's not the point.

using HDR mode on projector is not recommended.

you didn't by any chance added every resolution you could find under display mode didn't you? |

Hi. I'm Italian and new on this forum and I don't speak English very well.
I appreciate a lot the guide about MadVR and I'm trying to optimize it for my needs. I have a htpc with MSI Z390A-pro mobo, I5-9600K cpu, 16 Gb ram, Nvidia 1660 gpu, bd drive, ssd and nas with a lot of concerts and movies ripped from br discs. I have a Sony VPL-vw870es (calibrated BT2020) as projector and a Trinnov Altitude 16 as processor. I use Jriver Media Center 25 with MadVR, but I don't like to use more than one setup. So I set MadVR with PC levels 0-255,10 bit, already calibrated BT2020 pure power curve 2.20, 2160p23, 24, 25, 29, 30, 50, 60, tone map HDR using pixel shaders, tp 100, BT2390, highlight medium, measure each frame's peak; if in doubt, deactivate deinterlacing, disable automatic source type, force video mode, only look at pixels in the frame center; chroma ups. NGU Antialias medium, image ups. luma NGU Sharp, luma qu. direct qudrupole very high, chroma high; "use Direct3D 11..." and " "present a frame for every VSync" flagged in general settings, smooth motion only if there would be motion judder; ordered dithering, no flag in trade for quality. It works very fine with all 23.970 fps videos (4k hdr, fhd, etc.), without interlacing. But I've issue to watch 29.970 fps videos, with a lot of dropped frames, motion juddering and stuttering. I have a lot of concerts with this fps (Diana Krall, Carlos Santana, Miles Davis, ecc.). Can someone help me? Thanks. |

Are there benefits or harms by setting madVR for 2160p23, p24 in comparison with setting for 2160p59, p60 only ? Could that help to prolong the time a frame will repeat in...when the display switches to around 23.970 hz by playing 23.970 fps movies ?

I have noticed inconsistent behaviour when upscaling DVD to 4k, it behaves something like it isn't upscaling for some period of time and then it corrects itself and starts upscaling again. This can happen at arbitrary times, e.g. within a single scene without having touched any playback controls or changed any settings.
An example to illustrate, I created these by just replaying a scene on a loop. It rendered it "correctly" v few times, it is mostly looking bad. Look at the guy on the wire for the obvious difference. The fact this is two different frames is irrelevant btw as the effect occurs regularly on different content, i.e. it's not specific to one scene or one particular source file. Anyone seen something like this before? Any tips on how to resolve? Bad - https://ibb.co/7YLkcg9 Good - https://ibb.co/P6VwpKD |

Your screenshots are very low resolution, making it hard to judge anything, or even read the madVR OSD at all. Perhaps upload the original screenshots to a better image host?

This is not an issue with upscaling. It is due to deinterlacing working well or not. madVR either uses the GPU hardware for deinterlacing or it has its own IVTC algorithm if you put it in film mode. This behavior should depend on the DVD itself, is it telecined or true interlaced?
On that note, you do not want to use 25 Hz for this DVD. It is being deinterlaced to 50 fps, as indicated by the 20ms frame time. Edit: Your rendering times are very high for a 20ms frame time, perhaps the deinterlacer is getting confused due to performance issues? Try turning down the NGU 4x to medium, or maybe only double with NGU high, for testing. (maybe a problem with paused OSD... I shouldn't pay too much attention to the rendering times when paused. ) On desktop (Chrome) I got a link on the image to download the full resolution, which did get a good image.

Oh now I see it. Thats some bad UX for an image host.

Yeah definitely upscaling correctly, the obvious NGU upscaling can be seen throughout the image, definitely a deinterlacing issue.
You may wish to change between deinterlacing types to see what yields the best result. |

I'm not 100% sure how to tell if it is telecined or not, mediainfo reports Frame rate mode : Constant Frame rate : 25.000 FPS Scan type : Interlaced Scan order : Top Field First with regards to the "deinterlacing on" or "deinterlacing off" message, am I correct in thinking this refers to whether madvr or upstream is doing the deinterlacing? i.e. if on then madvr is deinterlacing, if off then something upstream is doing it. |

Try to enable film mode for those concerts (you can assign a keyboard shortcut key to it) and see if it is better. Quote:
This looks to be a PAL DVD you're playing. In most cases with films on PAL DVDs you can just force disable deinterlacing and you will get a 25 fps progressive image (I've got only one PAL DVD in my film collection where this isn't the case). You will then see 'deinterlacing off' and 'frame time 40 ms'
