Well, maybe but it's kind of pointless to optimize the downscaling since that's the part we don't have usually any control over (otherwise, why would we even downscale?). Catmull-Rom in gamma light is pretty realistic. You could argue that a box filter in linear light is closer to how cameras work, but I'd be surprised if it resulted in a huge difference in the relative quality of the scaling algorithms.

I was wondering if a post process sharpener specifically designed based upon the differences from an NG1 upscaled image and ground truth could be used to bring it as close as possible to ground truth, it does seem to be quite close as it is though.

I not crying. I'm just hopeful I don't have to open up my computer and drop some money into it. The most recent card cost me $100, used. It is good enough for my purposes, about equivalent to a PS4. I like what I have been able to do with old hardware. I am also a madVR nut, now, and that wasn't the case when I started with HTPCs. I do want to try NG1 and get some enjoyment from it. I still publish a blog on this software that is updated every week. You can't publish 2,000 words on madVR and not care about its features. But I really don't watch that much content these days? A movie every week or two and a couple of TV shows. That isn't worth a fortune or a GTX 1080.

This may be a very dumb question but I'm new to this so please bear with me. May I ask how can you guys capture an exact same frame from a video with different scaling algorithms? I want to try doing the comparisons by myself but I can don't know how to

It is easier if you use still frame images from the Internet. Do a Google search for 1280 x 720 images, or something like that. Seeing differences in live video is more difficult compared to a good still frame image. Drag the image into the MPC-HC window and press pause. Run your tests.

And how to take screenshots that have upscaling refinements applied? If take mpc-be the refinements don t appear on the image Enviado do meu iPhone usando Tapatalk

Hi, I've been trying for over an hour to fix a subtitle display problem that I'm pretty sure has to do with madVR rather than MPC-HC.
I have an "ultrawide" 21:9 aspect ratio monitor, and I use madVR's settings under Processing -> Zoom Control to zoom/crop past the hardcoded top & bottom "black bars" of most movies. The problem is that subtitles are still rendered as if those black bars are visible. The nature of the problem becomes clear if I just show you screenshots: This is what I see in fullscreen. (Notice the few pixels of black bar at the top and bottom - that's because 21:9 monitors aren't precisely the same aspect ratio as movies, but pretty darn close.) This is what I see in windowed mode. I thought that the fix would be easy: check the "move subtitles" option in madVR and choose one of the two options in the corresponding dropdown menu. However, neither of them seemed to have any effect at all. So I next tried all conceivable combinations of enabling/disabling the following options within madVR: Move subtitles (to bottom of screen) Move subtitles (to bottom of video) Zoom small black bars away Crop black bars No combination of those options seemed to have any effect on the subtitles at all, even when I closed MPC-HC and played the video all over again. Am I right that this is a problem with madVR rather than MPC-HC? Because none of the subtitle options in MPC-HC seem to have any effect whatsoever (although, neither did any of madVR's subtitle settings). If that's the case, then is there any way I can fix it? Let me know if there's any more information that would help diagnose this, or if there's anything you'd like me to test out for you in terms of a possible solution. Thanks!

Subtitle formats that specify position (e.g. ass) cannot be moved by madVR. What format are your subtitles?
If they are ass you can convert them to srt but it is a bit of work, especially if you aren't used to demuxing and remuxing already.

I always OCR my subtitles, Subextractor is a good option, but that is quite a lot of work you probably don't want to do. Sorry, but it isn't a madVR issue.

You can try MPC-BE, can move any subtitles - Ctrl+Shift+Arrow.

Is there at least a way I can stop madVR from getting rid of the black bars while in windowed mode? Because that way I could at least un-fullscreen if I really need to see a subtitle for some reason. When I took those screenshots I was under the impression I had it set to keep the black bars in windowed mode, but I think I simply paused the video before it had a chance to crop the black bars. Because no matter what settings I use in madVR I can't seem to get it to stop removing the black bars in windowed mode. |

Madshi called it NG1 and nautilus7 suggested NGS, you then asked why he went with "Next Gen" and quite simply it's because madshi himself called it Next Gen.
Considering NNEDI3 was made in 2009 and this new scaler is likely based upon that to some degree, it is accurate to call it such. Last edited by ryrynz; 16th November 2016 at 08:59. |

Is this for real?

About the name:
Since Madshi is the creator, the algorithms name should have "Mad" in it. Like "MadSG1" or "MadScaler". Only SG1 is too anonymous. Edit : SG1 is as we know the codename for the "Stargate SG1" TV series
