What's the worst upscaling in terms of quality?
I want to use it to compare it with the one I use now (chroma and image up: lanczos 3 taps + AR). For the moment I used bilinear + bilinear and these are the result with 2 different file: http://www.mediafire.com/view/uebjbagjb9vnnf2/a%2C 1.png http://www.mediafire.com/view/1asqfiruye3v7j2/a%2C 2.png http://www.mediafire.com/view/1z9v92xqg20vtje/b%2C 1.png http://www.mediafire.com/view/rzwfq7gatuzrdbw/b%2C 2.png (used Win8's win+stamp because the screenshots in MPC have the resolution of the file instead of the output, don't even know if it's normal) Maybe I have too much trade-off? Because the difference is barely visible (do you want to guess which one uses lanczos? ) Tradeoff I have: http://i.imgur.com/PLb5LCM.jpg By the way these are the settings that were already checked right after a clean install...I suppose madVR has some pre-built profile for specific hardware, and I didn't changed them. |

Nearest Neighbour is the worst quality.

Weird. Ok, one more thought: Is it possible that your media player has color or saturation controls set to non-neutral values?

Of course I could add even more settings to allow the user to choose just another algorithm for CbCr upscaling when using NNEDI3 for Y. But really, there are already more than enough options there. Adding even more might make it more logical, but also more complex. Quote:
I don't find any "Strg" in changelog.txt? Quote:

So what am I saying? The key thing is that you need to make up your mind what you understand as "maximum" settings. (Note: I don't really want an answer to the following questions). Which scaling algorithms do you want to use? When using NNEDI3, how many neurons do you want to use? And do you only watch 24fps movies? Or also 60i/p content? Which resolution does your display have? And which resolution your movies? Only with all that information we could maybe provide you with good advice. But even then, I personally wouldn't really know which GPU to recommend. There are pros and cons for most of today's GPUs. E.g. the 750 (Ti) is a nice GPU, but has no HEVC decoders and not as fast as the 960. The 960 is nice, and has HEVC decoders, but is not as fast as the 970/980. The 970/980 are quite fast, but they don't support HEVC hardware decoding. AMD also has nice GPUs which have their own list of pros and cons. So which should I recommend? I've no idea. Quote:

It does take a little explaining but it makes sense to keep all the algorithms the same after passing the first conversion to RGB. They would have to be the same if not using image doubling. If you listened to me I would probably come back and ask for a way to use the alternative chroma scaling even when not using image doubling. Quote:

Thanks, to clarify, I'm mostly interested in Blu Ray image quality (most are 1080p24) on a 1080p TV (no 4k) and second priority would be Australian TV which is 576i50, 720p25 and 1080i50. For Blu Ray I would like to be able to match the latest Oppo Blu Ray player. Any recommendations for a GPU and CPU for this? If it has low TDP that's a bonus. Thanks again. |

Are these level cards along with the GTX 960/970 overkill if not gaming or are they precisely the way to get the best video quality with madVR? Does madVR get used for gaming? (I don't play games) |

Ah, didn't check the actual changelog, assumed it was the same as the original 0.62 post which wasn't updated and still references Strg. Also the changelog on videohelp still references strg for 0.62 and 0.63, I'll get them to change it.

some scaler in madVR can be so demanding that even a GTX 980 can't handle them. it is simply up to what you want to use and what YOU think looks best to your eyes using your TV. a r7 250 can already be the best choice for you. |

Least you overlook 4K...
Just something to think about here..we're at a turning point where 4K starts to go mainstream in video cards. If considering tying the video card/PC into a '4k HT setup' sooner or later don't overlook 4K compatibility issues. Current cards support HDMI 1.4 which will do 3820x2160/60 but at up to 4:2:0. HDMI 2.0 has the BW to support that at 4:4:4 10-bit.
The first cards with native HDMI 2.0 appear to be in the AMD R 300 series - due to ship within a few months - with Nvidia to follow latter on. The other 'features' to look for are hdcp 2.2 and native HEVC H.265. Of course this is all predicated using a model of the very latest generation of 4K TV panels. As it stands today deciding later on that this would be doable by getting the appropriate 'adapter' will not be easy (if possible). |

I've been farting around with the 10bit h265 Astra.SES.Demo.HEVC.mp4 file. The 64-bit MPC-HC/LAV version plays it fine while it's a slide show with the latest 32-bit version. The difference on my i7-3770 3.4 GHz is like 50% CPU w/64-bit and 100%/slide show (dropping better than half the frames) with 32-bit (both using EVR(CP).

Do the Nvidia GTX 9 series not have native HDMI 2 support? I look forward to seeing if the AMD R 300 series also include VP9 decode support, if they move to a 20nm process and if they perform much better than the existing cards as there are more stream processors. I'd be grateful if Nvidia GTX 960/970/980 users could post some of their nnedi3 benchmarks. bcec has already done so with his 960 on avsforum, he had a render time of 35ms with nnedi3@32 with lanczos3ar so 30p content is only possible with 16 neurons. It was reported earlier that AMD cards perform better than their nvidia equivalents for nnedi3 die to their stronger compute and opencl performance, it seems while nvidia have closed the gap, AMD still have the lead. |

The GTX 960 is way more expensive than the 260x and has a higher TDP. |
