mpv Configuration Guide for Watching Videos


I also have a guide for setting up MPC-HC and MadVR if you’re less into tweaking. Other then being slightly less resource effecient at the lower end, imo MPC paired with MadVR is just way more convinient to use.

Table of Contents

These are my recommended settings. Adjust the settings suitable to your system.

Get mpv at or custom mpv build w/ vpy enabled configured by me. Just extract the archive to a desired directory. I recommend not using a directory that requires admin/superuser privileges. For Windows, an install script should be included but is not required, as all it does is register mpv for file association. For Mac, there’s also IINA which has a prettier UI although some advanced options may not work and may require more tweaking for power users.

The mpv.conf file can be found in %APPDATA%\mpv on Windows and ~/.config/mpv/ for Linux/Mac. Alternatively, \portable_config\ folder can be used in the mpv executable directory on Windows to make it portable, and will take highest priority over %APPDATA%\mpv.

Read the documentation for all available commands.

To illustrate how the config file works:

# This is a comment.
active-config # This is a comment.
active-option-value=222 # active-option-value is now set to 222 instead of 111. 

If you are still using notepad to edit files, I recommend using VSCode, Notepad++ or similar software to edit config files to make your life easier.

General mpv Options

Enable this section if you use SVP 4, requires Vapoursynth mpv build.
I also have an SVP 4 guide if you’re interested.

#input-ipc-server=/tmp/mpvsocket # *nix only
input-ipc-server=mpvpipe # Windows only

Built-in high quality profile. Enables better upscaling algorithm. Recommend GPU minimum of newer Intel Iris iGPU, AMD VEGA 8 iGPU, or NVidia MX150.


(Optional) Enabled newer Vulkan API. Disable if compatibility/performance issue. May impove performance when running complex shaders.


Override default language selection order:

alang = 'jpn,jp,eng,en'
slang = 'eng,en,enUS' # enUS for Crunchyroll.

Some other UI options:

keep-open=always # Prevents autoplay playlists. Set to 'yes' to autoload. Both "always" and "yes" prevents player from auto closing upon playback complete.
reset-on-next-file=pause # Resumes playback when skip to next file

window-scale=1.5 # Set video zoom factor.
autofit-larger=1920x1080 # Set max window size.
autofit-smaller=858x480 # Set min window size.

no-osd-bar # Hide OSD bar when seeking.
osd-duration=500 # Hide OSD text after x ms.
osd-font='Trebuchet MS'

Configure network/youtube-dl options:

ytdl-format=bestvideo[height<=?1080]+bestaudio/best # Set max streaming quality as 1080p.
# Default demuxer is 150/75 MB, note that this uses RAM so set a reasonable amount.
demuxer-max-bytes=150000000 # 150MB, Max pre-load for network streams (1 MiB = 1048576 Bytes).
demuxer-max-back-bytes=75000000 # 75MB, Max loaded video kept after playback.


screenshot-png-compression=7 # Setting too high may lag the PC on weaker systems. Recommend 3 (weak systems) or 7.

Video Config

Denoise filter. Recommend keeping it off unless watching CRT era stuff.


Deband filter. Always turn on for anime.

deband=yes # Default values are 1:64:16:48

Deband parameters configuration. For Anime, 2:35:20:5 recommended for general use. Use 3:45:25:15 for older DVD, badly mastered BD or WEB streams. Use 4:60:30:30 for really, really bad streams.

deband-iterations=2 # Range 1-16. Higher = better quality but more GPU usage. >5 is redundant.
deband-threshold=35 # Range 0-4096. Deband strength.
deband-range=20 # Range 1-64. Range of deband. Too high may destroy details.
deband-grain=5 # Range 0-4096. Inject grain to cover up bad banding, higher value needed for poor sources.

Note: For older/weaker iGPUs, instead of increasing deband-iterations you may need to increase deband-threshold instead if you need a stronger effect. I recommend 1:60:25:30 if you absolutely must run 1 iteration (lower quality but much less GPU usage).

Set to auto for Anime due to 8 and 10 bit encodes. Set to no if your monitor has built-in dither (just leave it at auto if you aren’t sure).


Audio Config

volume=100 # Set volume to 100% on startup.
volume-max=100 # Set player max vol to 100%.

Subtitle Config

Enable if subs are broken or you need legacy ssa support.


Enable to modify PGS subs.

#sub-gauss=0.5 # Blur PGS subs.
#sub-gray=yes # Monochrome subs (makes yellow font grey).

Allow loading external subs that do not match file name perfectly.


Default subtitle font when none are specified.

sub-font='Trebuchet MS'
sub-bold=yes # Set the font to bold.
#sub-font-size=55 # Set default subtitle size if not specified.

Advanced Video Scaling Config

Internal Scalers

Note: Press shift + I in mpv to view frame drops. Then press 2 to view frame times and processing layers. Make sure your config does not drop frames and ideally frame times should be <25ms.

scale is the luma upscale method. Prioritize resource on this over cscale.
dscale luma downscale method.
cscale chroma upscale method. Human eyes aren’t as sensitive to chroma compared to luma.

If you enabled profile=gpu-hq:

#Scaling algorithm for profile=gpu-hq

Default gpu-hq should be sufficient for most people, however, here are some suggestions for fine tuning:

I have a Toaster (crappy PC) edition:

scale=bilinear # Set spline16 if possible.

I have an iGPU laptop edition:


I have a decent GPU (GTX 1050+) edition:

cscale=spline36 # alternatively ewa_lanczossoft depending on preference

External Shaders

For those who have really good GPUs (GTX 1060+, sometimes need even better GPU) and want to run external shaders:

Remember to download the shader files and put them in the mpv config folder! ~~/xxx.glsl refers to xxx.glsl file in the mpv config directory.

Always enable profile=gpu-hq before using shaders for fallback.

Dynamic Scaler: SSSR
SSSR is a dynamic scaler that improves built-in scalers utilizing structure similarity. Upscale result varies widely depending on your scaler. You may freely choose your preferred one. Moderate to highly GPU intensive.

For a sharper image:

glsl-shader="~~/SSimSuperRes.glsl" # Set B C parameter to Robidoux.

Alternatively set to haasnsoft for a softer look (much better at artifact/aliasing supression). I found this combo to be very good for anime and performs close to NN based upscalers.

glsl-shader="~~/SSimSuperRes.glsl" # Set B C parameter to Mitchell.

If you really want to run SSSR on a lower-end GPU, the full power version of MX150 (1D10 25W) should be able to run it if you use the faster algorithms. Results will still be better than spline36. Use bilinear/spline16/spline36 (whichever your GPU can handle without dropping frames) for a sharper image. For anime, if you want a softer anti-aliasing look like haasnsoft, use bicubic.

glsl-shader="~~/SSimSuperRes.glsl" # Set B C parameter to Robidoux for sharper image, else use Mitchell (slightl sharper) or Catrom (default).
scale=bicubic # or bilinear or spline16/36

You can modify the SSSR shader’s cubic B and C parameters (on line 31 and 79) to your needs. Default is Catrom (0,1/2). Set to Mitchell (1/3,1/3) or even Robidoux (0.3782,0.3109) for a sharper image. See this graph.

2x Pre-Scaler: Neural Network Scalers
Some of these shaders require high-end GPUs to run smoothly. 2x pre-scaler means they scale a fixed 2x and should only be used if you have a 4K monitor (1080p x2 = 4K). For NN upscalers, more neurons = better quality but significantly more computational power.
Always activate profile=gpu-hq first.


Choose 1 of the 2x pre-scalers:

  • FSRCNNX is very good for general use / real-life content, may amplify artifacts (due to it being true to its source). Requires good source material. MadVR equivalent would be NGU-Sharp. Very GPU intensive.
  • RAVU Lite is relatively lightweight and decent for anime due to the lite version being sharper. I would use SSSR over this due to SSSR being better imo. Moderately GPU intensive.
  • NNEDI3 is designed for anime use. Result is very close to MadVR’s NGU-AA. Very GPU intensive.


cscale=spline64 # or ewa_lanczossoft (or your choice, really)

Dynamic Scaler for Anime: Anime4K
Anime4K is a unique upscaler + shader designed for Anime. It used to be very destructive, sharpens lines for a… unique “visual quality” look. It works extremely well in some anime and eh in others. Definitely isn’t for everyone. Version 0.9 had lots of flaws (mainly texture banding and line bloating). 1.0RC fixes a lot of the flaws (mainly bad banding) at the cost of doubling GPU consumption. 1.0RC2 optimized GPU usage (even more effecient than 0.9, 1080p > 4K should just barely run on a GTX 1030) and also introduced 2 more speed profiles for even weaker systems (supposedly the fastest profile can run on iGPUs at the cost of shader quality).

The latest 1.0RC2 tones down the “filtered look” even more and serves as an upscaler + filter of {line thinning + line smoothening + sharpening} + artifact/texture-denoiser (reduces jpeg-like edges) combo (note: filter only active when upscaling). One down side to Anime4K compared to other upscalers is that due to line thinning, anime with bad aliasing effects looks even worse (stares at badly made isekai anime magic circles).


For those interested in higher quality downscale:
SSIM downscaler is tuned to be used with mitchell. However, you shouldn’t be downscaling in the first place so just having dscale=mitchell fallback should be good enough.


For those inteested in higher quality chroma upscale:
Imo cscale=spline36 is already very good. Human eyes aren’t that sensitive to Chroma compared to Luma. I won’t be surprised if you can’t even tell the difference when simply using cscale=mitchell. However, if you just want the best of the best and have the extra processing power, KrigBilateral is a high quality Chroma upscaler.


I always advise testing out settings yourself, “quality” is extremely subjective. For example, in anime, destructive filters (denoise/de-ring/sharpen) upscalers may “look better” visually but not necessarily be true to its source (lower SSIM/PSNR).

If we go purely by measurement, haasnsoft should be a terrible upscaler (and it kinda is with normal content). However, when paired properly with SSSR it looks great in anime. Similarly, NNEDI3 looks better with Anime (as it’s trained for such) despite FSRCNNX is the technically better (accurate) upscaler.

Anime “visual quality” greatly favors algorithms that de-aliases, denoises and sharpens lines to be defined. This is why Anime4K is such a controversial upscaler as it takes these concepts to an extreme.

In terms of algorithm quality (Note: better quality usually = more GPU usage):

abc = abc built-in shader
[xyz] = xyz external shader (requires downloading glsl/hook files)

For scale:
[NNEDI3] or [FRCNNX] > [SSimSuperRes + haasnsoft/ewa_lanczossharp] > ewa_lanczossharp > spline36 > spline16 > bilinear
                <---------------------[Anime4K 1.0RC2] (personal preference)--------------------->

For dscale:
[SSimDownscaler] > Mitchell

For cscale:
[KrigBilateral] > spline64 / ewa_lanczossoft / spline36 > mitchell

input.conf Config

You may create an input.conf in the same directory as mpvconf to override default shortcuts. Here is a cheatsheet for the default shortcuts:


Keep in mind depending on your country keyboard, you may need to modify the file accordingly. For example, the key = has been ‘incorrectly’ mapped as + for default shortcuts (e.g. alt + = for zoom is mapped as alt + + which won’t work on the US keyboard). This is because in some countries the = key is the + key, and while on the US keyboard they are the same key the + is actually shift + =.

Basically when mapping, a means pressing a, but A means shift + a.

To fix the incorrect zoom shortcut:

Alt+- add video-zoom -0.1
Alt+= add video-zoom 0.1

To modify skip durations and add custom skip shortcuts:
Note that keyframe seeking is much faster (no render lag) but may not be exactly x seconds.

# Seek 5s exact, do not display OSD.
RIGHT no-osd seek  5 exact
LEFT  no-osd seek  -5 exact
# Seek 5s to the closest keyframe.
Ctrl+RIGHT  seek  5
Ctrl+LEFT   seek -5
# Seek 20s exact.
alt+RIGHT no-osd seek 20 exact
alt+LEFT no-osd seek -20 exact

Modify mouse wheel to control volume:

WHEEL_UP add volume 10 # In volume %.
WHEEL_DOWN add volume -10

Add audio delay hotkey:

ctrl+= add audio-delay 0.1 # In seconds.
ctrl+- add audio-delay -0.1

Add subtitle delay:

. add sub-delay +0.042 # 0.042s is 1 frame for a 24fps video
, add sub-delay -0.042

I came from MPC-HC so I remapped many shortcuts to the same keys.
Add full-screen shortcut like that in MPC-HC:

F11 cycle fullscreen

Add screenshot shortcut like that in MPC-HC:

F5 screenshot video # Video stream screenshot (extract video frame).
shift+F5 screenshot # File stream screenshot (video frame + render subtitles/signs)
ctrl+F5 screenshot window # Window screenshot (screenshot current player frame including OSD, shaders, upscale, etc.)

Cycle subtitle & audio like in MPC-HC:

s cycle sub
S cycle sub down # shift + s cycle backwards
a cycle audio

Cycle ASS subs style override:

u cycle-values sub-ass-override "yes" "force" "strip" "no"
ctrl+, add sub-scale -0.05 # Decrease sub size by 5%
ctrl+. add sub-scale 0.05 # Increase sub size by 5%

Cycle adaptive sharpen shader:
Note: Requires AdapSharp glsl in mpv conf directory. When AdapSharp is active sigmoid-upscaling needs to be no.

g change-list glsl-shaders toggle "~~/adaptive-sharpen.glsl"; cycle-values sigmoid-upscaling "no" "yes"; show-text "glsl-shaders='${glsl-shaders}'\nsigmoid-upscaling=${sigmoid-upscaling}"

Cycle deband on/off and weak/medium/strong:
Note: the ‘weak’ first set of deband values here needs to match the values set in mpv.conf or the value order will be messed up (in this specific case 2:35:20:5).

h cycle-values deband "yes" "no"
H cycle-values deband-iterations "2" "3" "4" ; cycle-values deband-threshold "35" "45" "60" ; cycle-values deband-range "20" "25" "30" ; cycle-values deband-grain "5" "15" "30" ; show-text "Deband: ${deband-iterations}:${deband-threshold}:${deband-range}:${deband-grain}" 1000

Visit the wiki or the default input.conf for more info.

mpv Custom Build

Here is a custom built mpv with Vapoursynth enabled (for Windows). Also includes a custom built FFmpeg in the folder. The folder is portable, and the settings are also in the portable folder. The OSC is also custom, delete osc lua and conf files if you want the default back.

Note: \portable_config\ folder takes priority over %APPDATA%\mpv folder. (i.e. \portable_config\mpv.conf will load instead of ~~\mpv.conf.)

Download the 7z or zip archive.

UPDATE: Newer mpv build 7z archive, includes newest Anime4K stuff. HOWEVER, the newer builds post v29 have an OSC bug where it fails to load my custom OSC half the time. If this annoys you, delete ~~\scripts\osc.lua and \script-opts\osc.conf and just use the default UI. I also included the older mpv.exe renamed as mpv.exe.old if you want the older stable executable back, though the newer version should offer better compatability with newer formats such as AV1 and HDR stuff.

  1. Hey, I downloaded your MPV custom build but i don’t understand everything is laggy when playing a video down to 23FPS and its really bad every frame is slow down :/

    Any way to fix this ?

    1. If you didn’t modify any settings, it might be a driver problem. Try setting the `gpu-api=vulkan` to `opengl` or `D3D11`. If you messed with the settings, you might have conflict depending on what you midified.


      1. It’s irrelevant. I didn’t go through it in my post, but DXVA usage is controlled by hwdec, which is set to auto by default. If DXVA is not supported (a.k.a. you have a system older than Windows XP), it will fallback to software decoding.


  2. Thanx for the custom build. Do you update this custom build with new versions of MPV when they come out? Is it currently on latest build on MPV?


    1. No, the newest build breaks my custom UI due to me hacking it together from an existing .osc. You can always compile a custom build yourself using media-autobuild on github.


  3. How can I make the forward and back button usable for next/previous file if there are no chapters? It’s useless in it’s current form.


  4. Thanks for this, though for some reason this build won’t display subtitle shapes, like obscuring boxes to cover up a sign to put english on it.

    Example here :

    At the bottom, the original japanese is supposed to be erased with a black box, the english didn’t fit very well so we did that and just re-wrote the japanese in too, but smaller.

    I don’t know if there’s any settings that could be tweaked to fix this, or if it’s just because it’s based on an older build of MPV?

    I tried your version because I was getting super-annoyed trying to config vanilla MPV.


    1. edit file “input.conf” open with notepad or notepad++ run as administrator, save as all files and encoding set UTF-8 with BOM

      # Mouse wheels, touchpad or other input devices that have axes
      # if the input devices supports precise scrolling it will also scale the
      # numeric value accordingly
      WHEEL_UP add volume 2 # default “seek 10”
      WHEEL_DOWN add volume -2 # default “seek -10”
      #WHEEL_LEFT add volume -2
      #WHEEL_RIGHT add volume 2

      ## Seek units are in seconds, but note that these are limited by keyframes
      RIGHT seek 10 # default “seek 5”
      LEFT seek -10 # default “seek -5”
      UP add volume 5 # default UP seek 60
      DOWN add volume -5 # default DOWN seek -60


    1. Inferior is very subjective. For example, psyco-visual optimizations hurt video quality metrics (even VMAF) in h265, but almost all encoders/groups use it as it improves visual quality to the human eye.

      As I mentioned in the post:

      > I always advise testing out settings yourself, “quality” is extremely subjective. For example, in anime, destructive filters (denoise/de-ring/sharpen) upscalers may “look better” visually but not necessarily be true to its source (lower SSIM/PSNR).

    1. I would slowly add settings and test them out. While your config file is “fine”, it seems that you just added a bunch of things without fully testing things. Some notes:

      – Deband might be too strong to begin with. See my recommendations. Also, strong debanding requires deband-grain to work well.
      – EWA filters aren’t affected by anti-ring if you plan to use it, although you’re currently using Anime4K
      – Make sure you actually enjoy the current settings. And make sure Anime4K interacts well with your grain injection (I have my doubts they work well together).
      – I probably won’t use built-in interpolation. IMO either disable it, or go with SVP 4.
      – Lots of options you added could honestly be omitted unless you really need them.
      – I would try hooking external shaders/filters one by one and testing if you really like them.
      – Again, make sure you actually enjoy Anime4K. I recommend trying out SSIMsuperres too.
      – You’re running a lot of stuff. Make sure your GPU is powerful enough and not dropping frames.
      – The manual ( is honestly the best place to see what option does what.


  5. I downloaded your version of MPV and have some questions about the config file, in particular the scaler settings.

    I noticed in your config file, you have all the settings there but then say “enable the section that matches your system/preference”. How do I “enable” the setting? Do I do this by deleting the other settings?
