Psst, am I crazy or does the "autospeed" script straight-up not work for changing playback speed in the compiles mpv+vapoursynth?  As I mentioned in the dedicated thread, I was trying to use it to make only 25fps videos play at 24fps, but it's not doing anything...

It may have been easier if you just used the newly-developed rusticl paired with the standard default kernel-level AMD graphics drivers and mesa 22.3:

I just never said much of anything about it because I've not managed to test it out myself just yet and therefore I cannot say from experience what the exact steps are to enable rusticl for AMD graphics considering that rusticl as a whole is disabled by default.

It wasn't clear to me that "meson" was an actual package that could be installed.  Also, nowhere in the wiki article is "meson" mentioned.

Nevertheless, that was all that was required to get it to work.

That being said, I still had to forgo AV1 because both libdav1d and libaom were throwing up the error shown in the below screenshots.  Not having AV1 decode isn't particularly important for this test system, but it would be kind of annoying to not have it for the final PC configuration (which could still be several months away).

Much like how reclock worked on Windows, I want to be able to slow down ONLY 25/50fps videos to 24/48fps with the corresponding reduction in audio pitch in order to cancel-out any PAL speed-up (PAL speed-down?) while leaving videos that are already 24fps/48fps and 30fps/60fps to play back as-is without any speed and pitch alteration.

The usual go-to solution seems to be to use autospeed.lua (not to be confused with autospeedwin.lua) but, for whatever reason, it just seems to do absolutely nothing on my Linux Mint 20.3 system despite using a really bare-bones mpv.conf file, not to mention that SVP itself works and other lua scripts are also working (most easily confirmed by the pause-when-minimize.lua script)..


Heck, my test mpv.conf file is so basic that I don't think I even really need to attach it as a separate file:

input-ipc-server=/tmp/mpvsocket
video-sync=display-resample
script-opts=autospeed-maxspeed=1.01
script-opts=autospeed-minspeed=0.9

(I don't even know if that would include the corresponding reduction in audio pitch that I also require but, at this point, I'm just trying to get things working at all)


This was tested using a specific 50fps video clip that I find to be extremely good for noticing judder re-encoded to 25fps (aka removing every other frame) and then making a second copy that was then encoded to 24fps by manually slowing it down a bit; from there I have SVP configured to always perform 2.5x interpolation.

And, as a sanity check, I also tried taking the very same aforementioned encoded-to-25fps video clip and made another copy that's encoded to 30fps by manually speeding it up, and then made yet another copy that was encoded to 31fps, also by manually speeding it up and with SVP configured in that test scenario to always perform 2x interpolation instead.

With my 60Hz display, if things were working, I would think that the 25fps and the 31fps videos would be played at 24fps and 30fps, but they are not and are noticeably juddery compared to the 24fps and 30fps copies, implying that autospeed is not doing anything.

(I even tried using the "script-opts=autospeed-osd=true" option under the assumption that it'd make things more obvious if the script is doing anything but, alas, no OSD showed up).

Apologies for the double-post, but I'm following the wiki to a T on a new installation of Linux Mint 21.0 Cinnamon that has had nothing done to it other than some minor GUI tweaks (set "Traditional" panel view, set desktop background, those sort of things).

Everything seems to go fine but, in the final steps of installing mpv+vapoursynth, I'm getting the following - what do?:

https://web.archive.org/web/20221025231615if_/http://0x0.st/o3cj.png

I even tried typing in "waf configure" in the terminal but it doesn't have a clue what that means, implying to me that "waf configure" is not a traditional terminal command in the way that something like "cd /." is.

(and the ".waf found" is just because that was the second time I ran the corresponding command, so it's just re-using the pre-existing .waf file - the above error still happens even on the first attempt as well)

For reference, I never had any issues on Mint 20.3 installing mpv+vapoursynth by following the wiki's instructions, but Mint 21.0 seems to be a different story...

Psst by the way, is the mpv compile option for dav1d by chance:

--enable-libdav1d

yes/no?  I only ask because it's not included in the list of mpv/ffmpeg options above (the same list that the SVP wiki page links to).


Chainik wrote:

-no-tray ? big_smile

Hmm, that works but has a worse result by subsequently displaying the SVP program window instead whenever SVP is launched.

I'm guessing the way it works is that you always either have the tray or the program window, and it is impossible to have SVP running in the background without having either of those be present?


Also, about the update notification, the issue is actually that I've set up my OS to do automatic background updates since I've even got TimeShift snapshots being backed up to a second drive, so this means that SVP is the only thing left that's basically displaying visible update notifications.  Therefore, alternatively, if there's some way to update SVP in the background through my package manager, then that would also totally work (and could actually even be preferable).  SVP being made available as a flatpak would also work because I similarly have my update manager set to automatically update flatpaks.

Unconventional question - is it possible to make the tray icon not be present?

Currently the only tray arguments I know of is -tray which is only for making the tray icon appear when, by default, SVP's tray icon is not visible.  But what about if SVP's tray icon is visible by default - is there some way to then tell SVP to hide its tray icon?

While I'm here, I don't suppose it's possible to tell SVP to never automatically check for updates?

Ehhh... I'm a PC hardware enthusiast through-and-through but software is actually quite a weak point for me (I cannot code worth a darn, and I have major trouble remembering terminal commands).

A big reason I switched to Linux is because I was becoming dissatisfied with the... "software BS" associated with post-7 versions of Windows that seems to become worse and worse with each subsequent version - "software BS" that, in my mind, gets in the way of just letting me using my hardware as I deem fit.

To give some perspective, I'm also a user of Pale Moon rather than Firefox or Chrome, and much prefer the "function-over-form" web design of the mid to late 2000s as is used by places like romhacking.net or vndb.org rather than the "modern" design seen on the likes of the websites for the Framework laptop or Linux Mint.

Speaking of which, keep in mind that I use Linux Mint which is quite the "baby's first Linux", and I would argue that it's better for beginners than Windows nowadays, in large part to its "no BS"-ness (which is amusing considering they've gone with a "modern" design for their website, but it's my understanding that they largely did it #1 for sort of marketing to "normies" and #2 they purchased a pre-existing site design since they didn't have anyone around to write one from scratch)

Sure enough, all I had to do was add:

Curiously, none of the 'tone-mapping' settings matched the result displayed by Celluloid; this isn't really a problem but it was interesting nevertheless.

Apologies for the late response - for some reason I was not getting email notification of replies...

Nevertheless, I was reminded of this thread when I stumbled across two random 18fps videos which is an uncommon enough framerate that I didn't have a manually-created profile for it.


David Webb wrote:
Chainik wrote:

all settings -> frc.target.tolarance, you can set it to the big enough value

This would be a good solution, except that it allows for rates higher than the monitor can do as well.

Yeah, I've discovered another scenario where, even on a non-VRR display, getting an integer value is ideal and the issue of it going to the integer above is problematic - Linux combined with mpv-plugin-xrandr.

(do note however that "mpv-plugin-xrandr" is by default configured to switch to your monitor's lowest refresh rate that's an integer of the video's frame rate which makes it poor for use with SVP; see my comment on the project's git on how to make it instead switch to the highest refresh rate that's an integer of the video's frame rate so as to make it work well with SVP)


If you use a monitor that maxes out at 75Hz and, for 30fps videos, your have your Linux PC automatically change your monitor refresh rate 60Hz via mpv-plugin-xrandr, SVP will still interpolate that 30fps video by 2.5x to 75fps if you use the "to screen" setting in SVP.  Furthermore, if you adjust the frc.target.tolerance setting to a larger value accordingly to get it to only interpolate to a non-fractional integer value, it will instead end up interpolating by 3x to 90fps.

I think this is because 75Hz is exactly in between 60 and 90, and SVP defaults to rounding up.  I say this because, with the same scenario but with a 24fps video and having your 75Hz monitor automatically change to 72Hz, adjusting the frc.target.tolerance setting accordingly and using "to screen" does indeed result in 24fps being interpolated by 3x to 72fps.

The "frc.target.tolerance" setting work-around would work flawlessly if it instead just always rounded down - this would allow even the rare monitor that maxes out at 85Hz would still have a 30fps video interpolated by 2x to 60fps when using "to screen" (or, in a more common scenario with a 144Hz monitor, have 25fps videos be interpolated by 5x to 125fps rather than to 150fps).

I don't suppose anyone know if something special needs to be done to make HDR videos look correct on an SDR display in the compiled mpv+vapoursynth?  They look overly blown-out compared to the same video played in Celluloid with the default configuration provided by Mint 20.3, and the result in Celluloid looks very similar to the SDR version of the very same video(s).

For reference I'm just using YouTube HDR videos for this; here's a very recent example video of such:
https://youtu.be/MuzwlZi7FP8

(the main reason I'm trying to do this is because I don't have the grunt to interpolate 1440p videos but I can do 1080p videos, and YouTube's HDR 1080p encode gets over double the bitrate of their equivalent SDR VP9 encode)

Could you quickly check if AV1 decode support works?  When I built mpv+vapoursynth on Mint 20.3 a few months ago, it was unable to decode AV1 video dsspite the very same AV1 video working in the "Celluloid" application that comes pre-bundled with Mint 20.3.

If you need an example AV1 video (note that it's a tiny 256x128 resolution in order to keep file size down):
- https://ttm.sh/wad.mkv

If you run into the same situation there I do where audio plays but there's no video nor even a video player, then you'll have to end the mpv process via the system monitor in order to get the audio to stop.

I'm just trying to figure out if there's an easy way on a 144Hz VRR monitor to get all of the various typical frame rates interpolating at their maximum integer factors without manually creating profiles for every single framerate.

From what I can tell, one currently has to manually create 6 individual profiles (7x for 20fps, 6x for 24fps, 5x for 25fps, 4x for 30fps, 3x for 48fps, 2x for 50fps and 60fps), and that's without considering that the user may very well want different settings for different resolutions as well, meaning you could end up with something like 18 or more (6 for 1080p, 6 for 720p, 6 for 480p and below, etc).

EDIT: make that 7 individual profiles - I just stumbled across some 18fps videos which, for 144Hz, would use 8x interpolation.

Maybe you're misunderstanding me?

With the test scenario of a 25fps video clip, the refresh rate at 60Hz, SVP set with "To screen" and "1m", that still results in it interpolating by 2.4x to 60fps with 60 unique frames in the resulting video...and 2.4 is not an integer value.

Just a simple question - is there some way to have the "To screen" interpolation option only work in full integers to whatever the maximum frame rate would be without exceeding the refresh rate?

What made me think of this is that my friend just recently bought a 75Hz monitor that supports adaptive sync, and I can't help but wonder if on such a monitor that playing 24fps video content would still interpolate to 75Hz (3.125x) rather than to 72Hz (3.000x).

And yes, you could make manual separate profile for individual frame rates, e.g. 3x for 20 to 25fps and 2x for 30fps but, with variable refresh displays becoming more common, this seems like a simple function that'd become ever-more useful going forward (especially with high-refresh monitors where this manual setup would be particularly tedious, e.g. on a 144Hz adaptive sync monitor you'd need to configure 7x for 20fps, 6x for 24fps, 5x for 25fps, 4x for 30fps, 3x for 48fps, 2x for 50fps and 60fps...).

I just found out that Rusticl supports OpenCL image support in mesa; if it's to be merged into mainline mesa then it'll be in 22.2 at the very earliest.

This would make GPU-accelerated SVP on AMD GPU hardware become way easier to setup (I say this typing from a Ryzen 4800U right now which apparently is straight-up not even supported by ROCm), and could similarly become the go-to solution for Intel hardware as well since the existing Intel OpenCL ICD Loader is no longer maintained and therefore has a questionable future.

UPDATE: Rusticl is now able to run Darktable's OpenCL which also relies on image support.

Using SMPlayer and SVP on Linux Mint 20.3. When I load a video, the video plays for a second or two, then stutters when SVP takes over. Any idea on how I can stop that?

Does the stutter persist for the entire time that SVP is running?  If so then you might want to try updating mesa - there was a similar sort of stutter issue I ran into with video playback on Intel GPUs that I believe updating mesa fixed but I can't say for sure (basically the issue only occurred on test OS installations where I just happened to never update mesa and, similarly, OS installations where I had already updated mesa just simply never exhibited the issue).  For reference I simply followed the usual "linux gaming" recommendation of installing the "kisak-mesa" PPA for updated mesa.

If the stutter only occurs right at the moment when SVP "kicks in" but then goes away after a second or so, then this might not be something that can be solved as it's something even I've noticed for many many years (going back to SVP 3.1) even on Windows with MPC-HC.

BTW while you're here, do you have the same issue that I do that I described above where double-clicking SVP's ".run" installation file on Mint 20.3 simply does nothing?  How did you work around that outside of using the old version of the installer from archive.org that I linked to on the previous page?

Does it work if you instead open the video file with SVP rather than mpv?

If it does work, then it simply means that something with the mpv arguments aren't set up correctly (which opening the file with SVP works-around by automatically appending the necessary arguments).

If it doesn't work, then something is broken with either SVP of mpv on a more program-level... but what that is I could not tell you as I am at best an intermediate Linux user (and even that is pushing it).


EDIT: One thing I personally had a bit of trouble with was actually putting the "mpv.conf" file in the correct location - it might be a good idea to include a test argument that would make it really obvious whether the argument is even being found by mpv, such as "speed=1/4" (without quotes) which will default the playback speed to 1/4th.

(and psst, you should have a better end result for 30fps videos if you run your monitor at 120Hz rather than 144Hz)

By contrast, it appears in the 'Additional programs and features...' update selection in SVP 4 Windows despite the according Windows PC not having Vulkan.


And yes, I know that you need to be using SVP v4.5.0.210, but the option still appears in the 'Additional programs and features...' update selection in the older v4.3.0.168 of SVP 4 Windows implying that the update option should at least still appear regardless of your currently-installed version.

25 Reply by Nintendo Maniac 64

(1 replies, posted in Using SVP)

Outside of using the new uber extremely demanding "RIFE AI" interpolation mode, the general jist is that a lower setting for a given option is smoother (e.g. Uniform is smoother than Adaptive and 23. Complicated is smoother than 13. Standard).

It must be noted that this "lower setting = smoother" does not apply to the options under the Miscellaneous options category nor does it apply to "Artifacts masking".  Also "Decrease Grid Step" honestly tends to be kind of placebo-level and I generally only find it useful if you have performance to spare.

The bigger problem is that smoother settings can also increase errors and artifacts and, outside of using the RIFE AI option, there's no universal best settings that balance smoothness and artifacts - you just need to try it yourself and see if the artifacting is acceptable to you or not.

However, there is one big universal way to increase smoothness and decrease artifacts, but it has nothing to do with SVP's own settings - it's all about making your screen refresh rate be a multiple of the source frame rate (e.g. if the video is 25fps, then a display refreshing at 50Hz is better than one that refreshes at 60Hz, same goes for 25fps--to-75Hz being better than 25fps--to->90Hz).  Custom resolutions may be necessary to achieve this but beware of your display skipping frames (note that TVs tend to be much more picky than PC displays), and even if you aren't using custom resolutions then I still highly recommend using MPC-HC's built-in "automatic resolution changer" or alternatively madVR's display modes functionality (do not use both however!); if you use mpv then use this mpv autospeedwin script.


Anyway, I'm a total frame rate junkie so I use quite intense interpolation settings, but I'll reference them as a starting point:

First off, set the interpolation multiplier / target framerate in SVP to To screen.

－ Frames interpolation mode: Uniform (max fluidity)
－ SVP shader: 23. Complicated
－ Artifacts masking: Disabled

－ Motion vectors precision: Half pixel
－ Motion vectors grid: 16 px. Average 0 for 1440p, 12 px. Average 2 for 1080p, 8 px. Small 0 for 720p, 6 px. Small 2 for 480p (none of my PCs are fast enough to interpolate 4k, so my settings max out at 1440p)
－ Decrease grid step: Disabled
－ Search radius: Large
－ Wide search: Strongest
－ Width of top coarse level: Large

－ Processing of scene changes: Blend adjacent frame
－ Duplicate frame removal: Do not remove
－ Rendering device: Do not change
－ Processing threads: Do not change

If you're watching 2D animation, then set "Processing of scene changes" to Repeat frame. If you're getting inadequate performance but your CPU usage isn't very high, then increase the "Processing threads" setting until you end up with full performance.

If artifacting is too great for your tastes, then the first step I suggest is changing "Search radius" to Average.  If artifacting is still too great, then either reduce the "SVP shader" to 13. Standard and/or keep reducing the "Motion vectors grid" setting until you are happy (the Standard shader setting is particularly useful if a video has moving thin lines); for 2D animation, avoid using 13. Standard and instead drop the "SVP shader" to 2. sharp (anime) if the artifacts from 23. Complicated are too much for you.
