are we still talking about running mpv from SVP's menu ("open file via mpv")?
and that mpv crashes at the point where SVP kicks-in?
in All settings, put "--log-file=d:\mpv.log" into main.setup.player_args (enter "player" into the search field first)
replace "d:\" with some writable location you actually have

then run playback and send the generated mpv.log file


OK, here it is, attached! smile

there's no PATH variable on Screenshot (45).jpg

Chainik, it's been several days since I've heard from anyone.  Are we still troubleshooting this issue or have we given up?

I think it is very odd that the video would start playing in mpv, pause for a second, and then disapppear.  The first part, of course, happens when the app is working, that is, the initial pause is due to SVP kicking in before it displays the notification in the lower left regarding the video profile, FPS, etc.  But then it just vanishes (haha).  So it seems as though the video is trying to start, the SVP app beings to kick in, and there is the failure point.  Any ideas.  It looks from the last event log I sent that there is no longer a warning that the path to C:\Program Files\SVP 4\mpv64 is the problem.  I that what I am reading?  What could it be?

I've uploaded the screenshots of two versions of the fix-- One where I simply add the PATH to the existing mix (Screenshot 50), and one where I remove the others and just keep the single PATH you instructed me to add (Screenshot 51).  Neither of them work, same problem exists.  I've also uploaded the event log for the Screenshot 51 trial.

I don't mean to interfere with your help but (I think) you're putting the path in the wrong variable location.
Go to SYSTEM VARIABLES which is the bottom box.
Double click Path.
If I'm not mistaken, C:\Program Files\SVP 4\mpv64 & C:\Program Files\SVP 4\utils should be located there, not where you have it in USER VARIABLES.
Select NEW & browse to the locations to add them.

Nothing happens when I double click on "path" in SYSTEM VARIABLES.  I just get a bell sound and the option to click NEW is inactivated.

- Open the Start menu, type env, and choose Edit the system environment variables.
- Click the Environment Variables... button at the bottom.
- Under User variables, find the row named Path and click Edit.
- Click New and paste the exact file path to your target folder (e.g., C:\Program Files\SVP 4\mpv64).
- Click OK on all open windows to save your changes.
- Close and reopen SVP for the change to take effect.

Hi Chainik, thanks for following up.  I've already done what you instructed to do several times.  Please see my above post on "31-07-2026 12:57:24" and look at Screenshot (45).jpg.

If you need me to do something more specific, please let me know.

run 'set env. variables for vapoursynth' again

Done deal. Still not working.  Hit "Open file via mpv.." in SVP app, video comes on, pauses, then disappears.  I can't believe it's been almost two months and we can't get this fixed.  Isn't all the necessary info in the event log?

I uploaded a new one...

EDIT:  Here may be another clue, when I try to play a video in SMPlayer with SVP enabled, it won't play any video, I get an error message (see above).  Once I disable SVP, I can play any video in SMPlayer using either their version of mpv or SVP's version (path).

I'm not sure what you mean, as I said earlier, I have limited software engineering abilities, I'm just trying to put the right words in the right boxes to get Smooth Video Project application to work.  If you need more error logs or screenshots to troubleshoot the problem, I'm right here to to that, but I can't guess what steps to take to solve the issue.  Please just give me a step by step procedure to get this done, such as "copy and past this line line exactly and put it in this box," etc.  That's about all I'm capable of doing here.  Thanks.

don't you see that mpv64 folder is not here?


As I've mentioned before I'm not highly technically inclined in software, mostly I just try to follow the instructions.  In SVP/Utilities, I clicked the "Set environmental variables for Vapoursynth.." and I even went into "edit environmental variables" to ensure it was set correctly per the instructions on the SVP website (see Screenshot (45) above).  Did I do this correctly?  What am I missing here?  What do I need to do now?

when you double click "vapoursynth filter" in MPC-HC's "External filters" list - what happens?

I'm not exactly sure what you are asking, but this is my best guess.  The first screenshot is what I get when I double-click on the Vapoursynth filter in MPC-HC.  The second screenshot is when I doubleclick on the AviSynth filter.

The first log I'm uploading (SVP native mpv) is from where I right click the SVP icon in the system tray and scroll up to "Open file via mpv..."  I click that, it opens up a window to choose a video file to play, I click on a video, the video starts, then pauses a couple of seconds, and then completely disappears.  That's it.

The second log (MPC Vapoursynth warning) is from when I open a video in MPC-HC.  The log I'm uploading though, may be one where the AviSynth filter is activated.  When I apply "prefer" to the Vapoursynth filter to MPC-HC the player simply crashes instantly and gives the error message in the "MPC-HC crash" screenshot I uploaded in the last post.  If you want me to try something else, let me know.

EDIT:  I forgot to attach the "MPC-HC crash" screenshot so I just added it.

Thanks for responding Chainik.  I have already tried everything you describe above.  I've attached screenshots of how I set the Vapoursynth filter (see Vapoursynth filter) and how the entire media player crashes after I did that (see MPC-HC crash).

As far a mpv bundled with SVP for SMPlayer, I've aready done that as well, to no avail.  (See attached screenshots 43 and 44).  Also, I've attached a screenshot showing that I've set the PATHs correctly in environmental variables (see screenshot 45).

If you read some of my posts from years ago I had problems with SVP not working with SMPlayer, but for the better part of a year or two, it's been working fine.  I have no idea what happened.  I changed nothing, and one day I woke up, fired up SMPlayer, and it stopped working.  I don't think the problem is with SMPlayer though, I think the problem is with mpv, because I can't even get the SVP internal mpv player to play a video, the video starts, pauses, and then disappears.  The standard fixes don't help, please don't say, just click the "set environmental variables for vapoursynth" in Utilities.  I'm way past that.  As I said, the whole thing was working for a year+  I'm not just setting this up for the first time.  What boggles my mind, though, is that doing a compete uninstall of SMplayer and SVP and then a reinstall still doesn't work.  If I were an SVP developer, I certainly would be intrigued and think of this as a challenge.  Please do and help.

I think the base and most important central clues to this mystery boil down to 1) The fact that I can't get a video to play through SVP's native mpv player and 2) the "RIFE only works via Vapoursynth!" error message in MPC-HC.  It would seem to me that the problem her is somehow focused on Vapoursynth.  But I'm not the developer of SVP, so I yield to you.

Install ChatGPT locally and tell it to play a video with SMplayer and fix any errors found.


I was unable to have the AI run a program off my computer.  I fed it the error log, though, and this is what I got:

The error causing the failure is right here:

07:39:30.419 [E]: Playback [2aabad7a]: AVS - Crop: YUV image can only be cropped by Mod 2 (right side).\n(C:\Users\cmsre\AppData\Roaming\SVP4\scripts\2aabad7a.avs, line 66)

The Cause
You are playing a video with an odd-numbered width/height dimension (850x480), and when SVP attempts to crop the frame for 3D/Side-by-Side processing, the resulting resolution violates YUV color format requirements. Standard 4:2:0 YUV video formats require dimensions and cropping coordinates to be even numbers (Mod 2). Because 850 divided in half yields an odd dimension or an uneven split, AviSynth throws a crop error.

How to Fix It
Disable Auto-Crop for Odd-Resolution Files: In your SVP 4 settings under Applications or Video profiles, look for the cropping options and disable automatic black-border cropping for videos with non-standard or odd resolutions.

Re-encode the Video: Alternatively, resize or pad the source video beforehand so that both dimensions are cleanly divisible by 2 (or 4/16 for best compatibility with motion interpolation).


Unfortunately, this "fix" didn't work either.  I've attached a new error log, please some developer look at this so I can use the product again..

Still waiting on some sort of resolution to the issue discussed above.  I'm unable to use the product until some movement is made.  If you need me to run some more error reports or something I'm happy to do that but the radio silence here is deafening.  Somehow Vapoursynth is not working, I think that may be the common issue with MPV player not working either standalone or with SMPlayer and with the error message I get with MPC-HC. 

I asket ChatGPT how I could install Vapoursynth myself to perhaps solve the problem and Chat said NOT to do this because it could interfere with the built-in path configuration etc., that SVP uses.  Chat said to have the SVP "development team" instruct me on how to correct their product.  That's what I'm trying to do here and am unsure what the problem is.  If there is no solution to the problem then please at least respond as so instead of just ignoring the issue.

It is not normal.


Thank you for responding to my quandry but I'm not sure what to do with it..  Before I even started this thread I tried opening a file via the SVP manager directly and I mentioned above that not only did I "set environment variables for Vapoursynth" within SVP manager I also manually went into "edit environmental varaiables" and made sure the path was there.  I even added the additional PYTHONPATH variable that was suggested in this article on your website:  https://www.svp-team.com/wiki/File:Vs-portable-env.png

Again, nothing has worked.  As far as my mpv not being from the SVP bundle, I'm not sure what to do about that.  Plus, what about the vapoursynth error I mentioned above happening in MPC-HC?  I'm not hugely technically inclined.  It would be nice to get a step by step process to get this to work again, even starting from scratch, which again I also have tried.  How could it not work going from a completely fresh install?!

More info that might help:  SVP works with MPC-HC but when I try to engage the RIFE engine, I get a warning sign in the lower right of the screen that says, "RIFE only works via Vapoursynth!"

Does this mean that Vapoursynth isn't installed or isn't working?  I thought Vapoursynth was included with the SVP installation package?

Update:  Did a complete uninstall of SVP and SMPlayer.  Reinstalled SVP only to see if I could get MPV player to work isolated from SMPlayer.  Did a full install, checked mpv player mpv shared library boxes, etc. etc., set the environmental variables, checked that the PATH was pointing to SVP/MPV and it still doesn't work.  The video starts, pauses as it usually does initially, and instead of the little logo that comes up in the lower left of the screen that indicates SVP is working, the video just disappears.  How could this happen?  I did a completely fresh install.  Again, it works fine with MPC-HC player.  AI chat says it must have something to do with vapoursynth but I don't know what that is or how to fix it... 

Chainik???  Anyone?

Here's another piece of info that might help.  ChatGPT suggested opening the mpv player directly from the SVP folder and then dragging a video in there to see if t worked.  An it didn't.  It just paused and crashed.  Now this is interesting because SVP actually works with MPC-HC.  So perhaps it is something with MVP player itself.  It's confusing becuase it worked for a long time and I changed nothing.  Now I can't get it to work at all.

I had the setup working great for a while and just today it stopped working again.  Has something changed over the past few days?

Typically, I'll open a video in SMplayer using the optional MPV engine and it works fine, now when I do it the player crashes and I get an error report that reads, "MPV has finished unexpectedly.  More info in the log."  Can someone help?  I've uploaded the logs.

By "not working" I mean that the two full-SBS left/right videos are merging when I go into stereoscopic mode but they are not filling up the screen.  The top quarter of the screen is a big black bar and the bottom quarter of the screen is a big black bar.  Plus, the image is stretched horizontally by 2x.  It basically looks like the photo you posted above only the two images are merged and stretched horizontally.  This only happens with full-SBS videos like the one you posted above.  Half-SBS videos work just fine.  They fill the entire screen and don't stretch the image horizontally.

There is what they call a "Stereo-3D filter" in the video options menu of SMPlayer where I can change the video from full-SBS to half-SBS and get it to play like that.  But the idea is to not lose half the horizontal resolution in the process.  The reason I bought a 4K monitor is so I wouldn't have to do that.  The only other options in the "Stereo-3D filter" section are to convert it to anaglyph or interleaved, which obviously isn't going to help me.

I'm assuming that there are members here that play full-SBS videos using SVP on there laptops or desktops using either glasses or a glasses-free 3D monitor.  What would really help is if someone just told me what player they are using and how they have it set up.  Maybe nobody is or they are just playing half-SBS videos.  It would be nice to know.

Hi, me again smile.  I'm back because I never got an answer to my question, "Why I cannot get full-SBS or top-bottom to work with SVP?"  A kind member of the forum was kind enough to respond to my question, but it did not answer my question.  It would be great if an SVP developer, such as CHAINIK maybe, could respond with a word or two. 

I have an Acer 4K spatiallabs laptop that can play "glasses-free" stereoscopic videos in full HD 1080p resolution.  They have their own, build-in SpatialLabs media player that can play all formats, half-SBS, full-SBS, top-bottom, etc.  So it CAN be done.  With SVP, all I can get to work is half-SBS.  I'm seeking an explanation for this or, better yet, a fix.  Is this an issue with SVP, or is it an issue with the "hosting" media player I am using, which is SMplayer which uses an MPV engine?  That is all I am looking for.

Is there a way to configure SVP to play full-SBS and/or Top-Bottom on SMplayer?  If not, can I configure it to work on some other media player?  Or am I stuck just using SVP to play half-SBS videos?  If that's the case that's fine, but I would like to hear it sraight from a developer, such as CHAINIK, instead of someone who is just guessing.  Thanks.

I know the laptop can play full-SBS videos because there's a built in "SpatialLabs player" that can play them just fine.  The player has other problems, though, such as you can't slow down the playback.  Therefore, I prefer to use SMplayer with SVP but can' seem to find why I can't make it work.

SVP has nothing to do with how your player presents a 3D image. That's purely down to your player and settings. However it sounds like what you are seeing is a 3840x1080 resolution image on the screen because that's exactly how it looks when presented properly. A thin strip going horizontally across the center of the screen with the top and bottom of the screen blank like the image below.

Ok, maybe I should have phrased my question differently and asked, "HOW can I get a full SBS video to play on my glasses-free 3D laptop?"  Oh, and by the way, I made a mistake-- the resloution of the monitor is a full 4K 3840x2160 resolution, if that makes a difference.

As far as media players, I've tried just about all of them, potplayer, KM player, etc., etc.  With the exception of the built-in "SpatialLabs player" the only one I can find that will play a Full SBS video on the laptop is Stereoscopic player, but that player has other problems.  For one, I don't think it's supported anymore and isn't undergoing ongoing development.  Two, it doesn't support SVP.  Three, and most importantly, it doesn't have an option to speed up and slow down video playback.  This is why I use SVP, so I can slow down videos and still have smooth playback.  I'm not an expert in these matters so if someone knows of a specific player that works with SVP and can play full SBS videos or can just help me with a solution in general, that would be great.

P.S.  Again, the built-in SpatialLabs player has an option to play 1) 2D-3D conversion (on the fly), 2) half-SBS, 3) full-SBS, and 4) Over-under.  So the monitor can seemingly play ALL formats available within the player.  However, the 3D software package also includes another feature called SpatialLabs "GO" where you can play any video on the screen in stereoscopic 3D as long as you can get the video into fullscreen mode (e.g. a YouTube video).  From here, you have an option to do one of two things, 1) if the video you're watching is in 2D, you can click a button that will convert it into 3D "on the fly," 2) if you are watching a side-by-side movie, as in the one dawkinscm posted above, there is a button you can click that will merge the side-by-side images into a 3D image.  There's not an option that will merge a top-down or over-under video, which seems odd.  So I'm not sure if this may be part of the problem or not.  Again, I'm not an expert.

I have an Acer SpatialLabs 15 glasses-free 3D stereoscopic laptop with 3840x1080 resolution.  I can get videos encoded in HALF-SBS to work just fine.  However, no go for full-SBS.  What happens is that the video image is "windowed" meaning that it only fills up a portion of the screen, such that there are big black bars on the top and bottom of the image and sometimes on the sides.  Plus the image is stretched out horizontally.  I usually use the SMplayer media player which uses the MPV engine.  However, I also have the same problem in MPC-BE.
