Why does it seem everywhere I look, people say mitchell is good at upscaling, and lanczos is better for downscaling, while the mpv manual states mitchell is best for downscaling and ewa_lanczossharp is the best for upscaling.
What about compute shaders v2 I need that shit in my life
Jordan Wilson
report this issue and hope dev could give an explanation. Or admit they messed things up
Colton Phillips
tech illiterate here, i'm on mac os and really happy with mpv since it handles really high res video way better than vlc and any other program i've tried. my question is how can i get it to resume videos from the last played position? google around a bit but no luck so far...
1. When you implement it yourself. 2. When you find a example of actual Matroska hard segment linking (NextUID/PrevUID) in the wild. (This is not the same thing as ordered chapters.)
Anthony Murphy
It seems like that line about mitchell was originally suggested to be put in by lachs0r 0x0.st/92
When it was made the default for opengl-hq, the commit note says "several people agree that it's a good filter for downscaling", despite what general opinion seems to be 0x0.st/9_
Guess we would need an mpv dev or somebody who knows better to tell which one is correct.
also, Sup Forums's spam filter is fucking horrible, so short links.
Grayson Allen
thanks bud, i'm retarded. i kept looking for a command or something lol. sometimes thinks are easier than you think

>diff.pics/g813R3To2Mn5/1 looks reasonably good, but it's somewhat hard to judge ringing artifacts with this image. which fsrcnn kernel configuration is this?
Lucas Kelly
There's an option to force ass into black bars as well. It's just image based subs (DVD/BD) where it's not possible.
Mason Gonzalez
2x ratio, 56,12,4, MS-SSIM (I fixed it), 120 epochs on expanded data (took 4 hours to train).
Connor Sanchez
Wait, lanczos is not ewa_lanczos! Completely different.
William Perez
Normal lanczos is even worse than spline36, which is used in opengl-hq. Ewa is better than both by far.
Caleb Phillips
so the "official" fssrcn kernel? the "big"/slow one? is there any hope to run that in real time? thx.
My monitor and the source is 1080p I thought it was supposed to work all the time. Thanks.

I keep seeing stuff about using neural nets trained on imagenet data but I never hear about anyone training on a data full of anime images in particular. Has no one tried it?
Blake Price
isn't that what waifu2x did?
Dominic Russell
For people that ask which downscaler is better. This image was made on avsforums by some experts and approved by madshi few years ago. As far as i remember people always suggested to use catmull_rom (bicubic 50) for downscaling (in madVR). Its sharper than mitchell but is somewhat less natural and has more aliasing and doesnt hide source artifacts. In theory mitchell is better for downscaling. Plus SSIM is designed by igv to work with mitchell.
Carson Morgan
Another "guide" created by lots of experts and also approved by madshi in madVR thread on doom9 few years ago.
Jonathan Ortiz
Man, it really isn't a madVR algorithm unless it has a meaningless acronym.
Chase Brooks
There is also this image about dxva scalers used by different GPU manufactures.
Jack Phillips
Why does it say scale=billinear even though I have set scale=ewa_lanczossharp?
Brody Scott
Not quite, waifu2x has a few different models. The ones corresponding to anime aren't anime itself but rather "anime-style artwork". This includes stuff like fan-art, manga covers and promo-art, doujin stuff, etc...
Dat intel. Its not possible to use dxva as upscaler in mpv, right? Could be cool for people with older intel iGPU's.
Carter Butler
Got a question about my config (see )
Does it make sense to use lanczos on 4k videos if I have a 1080p screen and like sharp images or will the image get "too sharp"?
Grayson Hall
Literally erase your whole disgusting config and use profile=opengl-hq cscale=ewa_lanczos scale=ewa_lanczossharp
video-sync=display-resample interpolation tscale=oversample You can also add SSSR shader.
Robert Bailey
Why though? By the way I didnt just copy&paste it. It was a long time ago and I might have made some mistakes but I remember that I had to get rid of the smooth motion which triggered me.
Lincoln Scott
>but I remember that I had to get rid of the smooth motion which triggered me But you have tscale=oversample ???
Joseph Martinez
Bro, are you watching cartoons?
ain't you too old to be on that disney?
Ethan Allen
Nice squat, good form.
Nicholas Gray
Ass to grass.
Jaxson Young
Okay, seems you're right. Got two more questions:
What speaks against hwdec=d3d11va-copy opengl-backend=angle
It helps with performance and if I understood correctly, there shouldnt be a quality loss if I use d3d11va-COPY
Second question: I don't know much about shaders but why SSSR over FineSharp?
Ryan Carter
What CPU do you have?
Andrew Jackson
Hey, it's, "Linked mkv support, industry standard right-click context menu, volume control, non-retarded keybinds, ability to properly count, and Doom9 unbanning when?"
Grayson Perez
Xeon 1230v2
Brayden Ross
HOLY SHIT. I just noticed that downloads on shinchiro's mpv build skyrocketed after mpc-hc death! Amazing.
You dont need any hardware acceleration. It might only be necessary for some super heavy 4K test video. Hardware acceleration often fucks shit up. If you can its better avoid it. >I don't know much about shaders but why SSSR over FineSharp? FineSharp is better used with higher quality sources or after doublers (like nnedi3) only because it sharpens artifact. SSSR is less picky about source and in theory provides image close to the ground truth original. Plus SSSR has built in antiringing.
Jaxson Torres
How the sweet fuck to I get vp9 hw acceleration on Windows?
I have 1080p vp9 60fps webm video from youtube, if I play it in Chrome or on youtube it is hw accelerated but if I open in in mpv it isn't.
Colton Robinson
>Hardware acceleration often fucks shit up. If you can its better avoid it. I keep hearing this meme and I think it's just the same user posting it over and over again.
It may be anecdotal but I've never had any problems with hardware acceleration. I mean it's possible that on some hardware configurations, on some operating systems, with some drivers, some users may experience some problems on some files.
As far as quality degradation, I think that depends on what is being decoded and with what hardware. From looking at the github issue tracker a bit it looks like it's limited mostly to corner cases and unsupported stuff that should no longer even be possible to trigger.
Justin Murphy
You have a shit CPU? Put hwdec=auto into config.
Dominic Moore
>Computer with Wangblows >Download any mpv version >Right click video and try to set mpv as default program >After selecting mpv in its directory just reprompts for default program Why?
Liam Myers
>You have a shit CPU? No but it's a matter of principle, I should be able to use hwdec when the machine I spent good money on does it well.
>Put hwdec=auto into config. Doesn't do fuck all unfortunately, I've tried auto, dxva* (all crap), d3d11va (works best for me with everything but vp9) as well as various backends win (works but no improvement), dxinterop (completely not working) and cuda (only copy works and also no vp9 hwdec).
Wyatt Parker
There was some batch script that I used that set mpv as the default program and everything. No idea where I got that though.
Logan Baker
>I keep hearing this meme and I think it's just the same user posting it over and over again. Its not a meme. Its been known for ages. Its always suggested (even by madVRfags on doom9) to be turned off if possible. Use shinchiro's build and run install.bat. Right click and choosing mpv as preferred program works for me though.
Thank god I haven't used Wangblows in years. Linux software is soooo much easier to use on Linux. Everything just werks.
>madVR >doom9 Aren't those just wangblows fags who still live in the codec pack era of video playback?
Ian Barnes
Yeah they had the script right next to all the mpv builds, thanks. Still don't know why mpv's the only player I've tried that does that though, it's not even applicable through the control panel (on this computer at least)
Joseph Sullivan
Why did you put the name in forward-slashes?
Ryan Fisher
I'm using a nvidia graphic card, should I use dxva2-copy or cuda-copy?
Cameron Morris
Because that's how Sup Forums works you dipshit.
Ryder Stewart
I think FineSharp wins the placebo battle
Jace Moore
Cuda-copy has best performance on my 970
Isaiah Richardson
I haven't updated mpv in just about a year (v0.20.0) What should I expect? Were there many major changes? Will all my configs break?
Gabriel Scott
Try using that script that gives you performance stats and see which one performs better.
Nicholas Bennett
>Hardware acceleration often fucks shit up. If you can its better avoid it. I have just been trying out different shaders to find out which one suits me the best and hardware acceleration adds some artifacts to the image lol. Maybe I can record it. Seems like you're right
Ian Perez
Cuda seems way faster under windows: 3.8 ms to render a frame with cuda and more than 10 with dxva2.
Kayden Bell
That probably has less to do with windows and more to do with your GPU and video card drivers.
Samuel Young
That's because with cuda your GPU works at highest frequency always.
Mason Wright
What type of file are you playing? What is your setup and your mpv.conf? Also, do you get this with all supported hardware decoders including copy-back decoders?
Jeremiah Russell
Wtf are those artifacts. First I tried disabling hardware acceleration, which didn't work. But if I remove profile=opengl-hq only, those artifacts do not appear.
