I cant test it atm but disable deinterlacing in madVR should be "weaving". |

I read it, and from different sources too.
In particular I found really helpful this. At the bottom there is a pal section. http://foro.doom9.org/ivtc-tut.htm

Hi, madshi. In the latest 0.92.12 whenever I try to take a screenshot when paused, the potplayer crashed. And taking a screenshot when playing will get me an abnormal image(strange colors like a thermal image of the original one).
I haven't changed any settings and it can just take screenshots without any problem in older 0.92.X versions. I use WIN10 with RX480. Maybe the problem in changelog of 0.92.11 "screenshots in paused state sometimes crashed madVR" is still not fixed? Just a guess. Anyone have some ideas or the same problem? ---------- And another problem. I use lav 0.71 with latest madVR in D3D11 native mode, and the picture is always(no matter what video) split into the top and bottom part. The top part is the picture content turned into a flat size, and the bottom part is often a green image. While D3D11 CB can just play normally. Is there any idea about the problem? nevcairiel said it sounds like a driver problem and madVR handles the processing of "native" frames. So I report it here. Thanks.

Anyway madVR needs frames for further processing. So what to do with Pal DVD with fields? Try "field combination" (aka "weaving", "weave deinterlacing", "no deinterlacing" etc.) to get (the original) 25 frames and if it doesnt work (combing artifacts) use GPU deinterlacer (50 frames, but less artifacts). For NTSC DVDs it's the same but you can try IVTC first in order to get (the original) 24 frames wihout pulldown jitter. Imho this dicision has to done by the user for every DVD, but field combination for Pal and IVTC for NTSC should work most of the time. Thats it. |

I read a lot about deinterlacing and ivtc but I limited to the general theory and not their algorithm, because I thought that was madvr to do that in one way. I was wrong at this point, I understand the sarcasm but I'm trying to learn and this topic I found it not so easy to go in. So I'm going forward just a step at a time.

Afaik enable Deinterlacing in madVR means GPU-Deinterlacer (video mode) or IVTC (film mode, for NTSC) and disable deinterlacing means field combination (imho "weave deinterlacing"), but maybe someone with more informations about the inner workings can confirm that?

I had to revert to 385.28 (the last version fully working with HDR and custom res, i.e. without the locked bit depth for custom resolutions). ASIO4ALL works fine again. If you don't need ASIO4ALL, 390.77 is fine, apart from the minor issue of the locked bit depth with custom res. One last advantage of 390.77: it solves the annoying Dolby Atmos bug in the sound control panel that switches the surrounds and the surround back speakers. Nice for those who game in Atmos. Not an issue for movies as the 7.1 config works fine to bitstream Atmos to the AVR (if you bitstream HD Audio to keep immersive sound).

That must be something on your end, shows up just fine here in the device list in the ASIO4ALL control panel.

deinterlacing is not that complicate.
if you take a PAL DVD and you can disable deinterlacing(PsF source...) and get normal results that doesn't mean you can do it with all pal dvd... maybe i didn't make my self clear but automatic detection does NOT work. |

I'm not the only one to have this issue on a 1080ti, at least with Windows 10 1709 and the latest nVidia drivers. That's how I found out as initially I had no idea why the HDMI out of the 1080ti did not appear. The other guy with such an issue was also using Windows 10 and a 1080ti, so maybe it's restricted to some nVidia GPUs only, but it's definitely a driver compatibility issue with 390.77, reverting to 385.28 immediately solved it here. https://www.avnirvana.com/threads/pr...-drivers.2147/ This guy has exactly the same issue, and I promise it's not me All my details in my sig, I was using Asio4all 2.14 as well and the latest stable REW. I don't know which GPU driver version breaks it, I don't have the time to try all the drivers from 385.28, I just went back to that one because it's the last one where everything works for me including the bit depth with custom res. When I'm done with REW (I just got a new AVR, so I have some set-up / testing / optimization to do) I'll probably go back to 390.77, it's a good driver otherwise.

I'm also on 10 with a 1080Ti, using ASIO4All 2.14. I'm not actually using REW, but thats not really involved at that point anyway.

Is there a way to manually calculate the required values to get a specific refresh rate? I've tried changing some of the values but each change results in a way to high change in the refresh rate. |

Which build/version of 10 are you using? I'm on the latest 1709.

Obviously there are other applications that can use ASIO, not only REW. I only use it for testing not day-to-day use (ASIO4All is usually a bad idea anyway, adding extra middle layers doesn't improve anything, unless you have some silly stubborn software that refuses to support any mainstream audio API, my USB DAC on the HTPC also has a native ASIO driver anyway), but I tested right now with JRiver Media Center.

Asio4all is the only way to access each of the 7.1 channels independently in REW. With the Java drivers, you're limited to sub + LR, so please don't make statements about software you don't use/know, or provide an alternative When I'm done with REW I'll go back to 390.77 and I'll check with jRiver. If it works, I'll get in touch with the developer of REW as it will point to an issue with this specific software. If it doesn't, it will confirm the incompatibility of 390.77 with Asio4all, at least in my setup and that other guy's. Sorry for the OT everyone, let's go back on topic.

I have actually used REW before though, but its just not something you use every day, or even every week, so its not installed for testing right now. Although they say you should re-measure occasionally, but who got time for that.
