Hybrid(Windows/Linux/Mac): Input -> x264/x265/Xvid/VP8/VP9

[locotus]

Thanks, going to tray it, I'll let you know.

[locotus]

Sorry, renaming ibmvtools_old.dl with both versions of libmtools. dell didn't work, indeed Hybrid traid to load but vanished without messages. Thanks anyhow, I'll go back to Hybrid_2025.05.18.2.

[Selur]

The issue is probably the libmvtools dll, does it work if you replace the ibmvtools_old.dll with the ibmvtools.dll from 2025.05.18.2?
Like I wrote, I can not test this, so this will not be fixed in any upcoming version unless I know what dll works.

Not yet, I just reinstalled it, and started a new conversion. But I'll do it later today and let you know.

[Compositor]

I ran into trouble while trying to install the latest dev version. At first, Windows Smart App Control blocked the executable from running. I copied it over to another drive and was able bypass Smart App Control to install it but Hybrid wouldn't start because it seems one of the exes was unresponsive for too long according to Windows.

I tried installing an older dev version from January that I had around, but that one couldn't bypass Smart App Control even if I copied it around.

I'm currently without Hybrid. I would like to use nvenc but as you know the last stable version has a problem with one of the settings for NVEnc.

[Selur]

a. no clue what Windows does with its Smart App Control.
b. Hybrid does call the tools it uses to get there version and if it doesn't get a response from a tool it stops, since clearly something is broken.
(usually something is interfering)
I'm not having these problems here.

Last stable version is 2026.03.21.1 and anything that was fixed in a dev till then is also fixed there.

Cu Selur

Ps.: Personally I have exemptions for Hybrids own folder, Hybrids temp-, engine-, debug- and output-folder in Windows Defender and MalwareBytes, which I use on Windows. Also, I moved all those files off my system drive.

[Compositor]

After some struggling, I'm glad to report that Windows finally let the installer work. Still had some trouble with some of the executables in the folder being blocked from running for a bit but that seems to have cleared up and I've been able to start Hybrid repeatedly now.

I'm back in business.

EDIT: There's one thing I've been meaning to ask. Running the Hybrid executable always starts a new instance of the app, even if one instance is already running. Is this intentional? I would think it would be safer to just switch to the existing instance if there was one running already.

[Selur]

Did you do something for it to work, or did it just work after a while since probably the Windows online database of Smart App Control changed?

Is this intentional?

Yes and No.
I'm aware that this happens, since Hybrid has no check to see whether an instance is running and can't switch to an existing version.
No, it is not intentional, since I never wrote code for this behavior to be.
Yes, it is intentional, since I'm aware of it and often use multiple parallel running Hybrid instances and did choose not to write code for Hybrid to actively trying to not start if there is already a running version.

I did send a feedback to MS complaining about it last night. Maybe that did have something to do with it.

Cu Selur

Made the test today, with no luck. Sadly didn't work. Thanks anyhow.

[Selur]

So even the libmvtools.ddl from 2025.05.18.2 didn't help.
Does any of the dlls from
https://github.com/dubhater/vapoursynth-mvtools/releases/
or
https://github.com/Mr-Z-2697/vapoursynth-mvtools/releases/
work for you?

Doesn't the Vapoursynth Preview work at all, or only if specific filters are used?

[locotus]

None of them work, but I forget tryng the preview thing. Tomorrow I'll do it.

[Selur]

Let me know, maybe I was wrong and it is a problem with a newer version of some other filter which causes problems on older CPUs.

Below is the debug after the preview crash, using Hybrid_2026.03.21.1.

[Selur]

a. if you switch versions: reset your defaults.
b. the debug outpu only shows:

2026.03.25 - 11:38:44_Windows 10 Version 22H2 (64bit)_2026.03.21.1 - level 9: Preview::indexingIsFinished 'VAPOURSYNTHPREVIEW' ignored,..
2026.03.25 - 11:39:15_Windows 10 Version 22H2 (64bit)_2026.03.21.1 - level 9: player finished,...
2026.03.25 - 11:39:15_Windows 10 Version 22H2 (64bit)_2026.03.21.1 - level 9: ExitCode: -1073741795, status: 1

Which usually indicates that a filter crashed in a horrible way.
Looking at the script I see you are calling:

# Denoising using QTGMC
clip = qtgmc.QTGMC(clip, Preset="Fast", InputType=1, TR2=0, SourceMatch=0, Lossless=0)
# contrast sharpening using CAS
clip = core.cas.CAS(clip, sharpness=0.750)
# sharpening using LimitedSharpenFaster(Mod)
clip = sharpen.LSFmod(clip, strength=300, edgemode=3)

The question:

Doesn't the Vapoursynth Preview work at all, or only if specific filters are used?

still remains and is probably the crucial point, atm. the following libraries are loaded:

core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/DenoiseFilter/ZSmooth/zsmooth.dll")
core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/SharpenFilter/CAS/CAS.dll")

core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/DenoiseFilter/DFTTest/DFTTest.dll")
core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/Support/libmvtools_old.dll")
core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/Support/fmtconv.dll")
core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/Support/libllvmexpr.dll")
core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/GrainFilter/RemoveGrain/RemoveGrainVS.dll")
core.std.LoadPlugin(path="D:/Hybrid/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/LSMASHSource.dll")

try disabling the filters one by one to check which might cause the problem
Additionally try whether:

• disabling QTGMCs 'Neo' option helps
• switching "Filtering->Vapoursynth->Misc->Script->Expression handler" to 'std' helps

Cu Selur

[locotus]

Change to "Neo" also crashes, see debugs below. Couldn't find Expression handler" to 'std
in Vapoursynth->Misc->Script->Expression handler" to 'std' , the only selectable, besides one greyoyt: SNEEDIF-EEDI3VK-VsFiltermod-Assrender. Thanks.

[Selur]

Ahh, the selection is disabled when noAVX2 is detected.
=> looking into it.

[Selur]

Uploaded a new dev, which should allow selecting "Filtering->Vapoursynth->Misc->Script->Expression handler".
Try whether selecting "std" helps.
If it does not help, try the filters one at a time, so that it more clear which filter and library is causing this.
Thanks!

Silly question here: where can I download it?

[Selur]

Dev versions are always in the 'experimental'-folder of my GoogleDrive, which is linked on the download page.

Ok, thanks.

[Platos]

latest dev + torch I uploaded yesterday evening does support vs-rvrt
like I wrote in the post over at doom9s: " you might want to enable 'Lazy Chunking'/'preview_mode' and lower the chunking values, if you use the filter in a preview."

rvrt on 4k content => you are probably running out of VRAM.
You will have to adjust chunking and or tiling, to get that working, see: https://github.com/Lyra-Vhess/vs-rvrt/blob/main/README.md
You should probably try on some SD content first to see whether there is another issue.
Also you might want to enable 'preview_mode' (= Lazy chunking) otherwise the whole clip will have to be processed before you see anything,..

[locotus]

After installing DEV it worked with QTGMC, without the sharpeners, adding LFSMod and CAS crashed. changing LFSmod with MSharpen worked. so it seems LFSmod was the culprit. Thanks.

[Selur]

Okay, so it is something that LSFmod uses, so it must be zsmooth, since CAS with MSharpen works.
Ah, looking throughout my code it seems like everywhere else I made sure that zsmooth wasn't used on non-AVX2 capable systems.
=> uploaded a new dev, which should not load zsmooth, but removegrain which hopefully should fix the problem with LSFmod too.

Cu Selur
Ps.: let me know if you find other filters that crash.

I did try it with a 1080p video (i have no 720p video or lower). I tried it with "Force Tile Size" 16 64 64 and "force tile Overlap sioze" 2 20 20. Rest was default and i used deblur gopro. I got a instant-crash like before and i checked VRAM Usage and it did not make a single dip and i have a 300ms readout rate, so i do not see any VRAM overflow. What does that actually mean "run out of input" in vapoursynt h error? Is it possible, that my 7 second video is to short ? should not be right, because the testvideo on RVRT-Github is not really longer.

[Selur]

Does it help if you enable 'Lazy Chunking'/'preview_mode' ? (otherwise the whole clip be processed before any output is shown; so if the source has some issues you might run into problems)
I can try here, if you share that clip.

[Platos]

You mean if it does help for preview or for encoding ? But no, if i enably Lazy Chunking preview does not work (same error run out of input) and also it crashes when i want to process the video. I do not se "preview_mode". I also tried to lower "Chunk size/overlap" on this chunking-setting. Also force tile size in combination does not work.

Edit: I saw you have uploaded a new dev with new vapoursynth and vsmlrt yesterday. I will try it with that. Does vsmlrt work with RVRT ?

[Selur]

You mean if it does help for preview or for encoding ?

I use it for both.

do not se "preview_mode". I

the parameter is named "preview_mode", but I named the option after what it does 'Lazy chunking'.

Does vsmlrt work with RVRT ?

afaik: No

Cu Selur

[Platos]

Ah and yes, sorry, i forgot to post the video:

And yes, i did activate the lazy chunking. It did not work.
