R47.2 released. You should definitely update if you use a previous R47 version since it fixes the merge bug introduced when converting everything to intrinsics.

When I go to update I get Python 3.7 (64 bit) is installed for the current user only. Run the installer again and select "Install for me only" or install Python for all users.

I only have one user on my PC and when I installed Python I selected install for all users. What am I doing wrong?

Update from which version? Does it actually work if you select to install for the current user only?

Do you have any registry entries in HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\3.7?

I uninstalled previous version and have since deleted it so not sure which version I had previously. I don't have any registry entries there?

Then you've most likely installed python only for the current user...

Thanks! A bit strange that it's %appdata%\Roaming\Python\Python37\site-packages and not %appdata%\Roaming\Python\Python37\site-packages\vapoursynth ...

Install for all users is selected by default and I didn't unselect it.

Benefits of Exprt build:

• Higher framerate in Exprt-intensive scripts
• Higher framerate in MaskTools-intensive scripts
• Lower electricity bill
• Lower CPU temperature

As a reminder: you need to replace vapoursynth.dll both in the installation path AND in the python module directory (where vapoursynth*.pyd is located)

Typically:
C:\Program Files\VapourSynth\core
AND
C:\Program Files\Python37\Lib\site-packages

Go test this so it can be included in the next official release. And test the MVToolz optimizations too.

Did the image reader plugin got removed in the newer version? I couldn't call it in vs editor.

It's not included in the installer so maybe you don't have it...

What package is it in now? The vs documentation still listed it as included plugin from the installer.

Here are some numbers:
Tested like this
PS D:\> vspipe.exe -p -e 5000 D:\del.vpy .
on a Ryzen 2600, 16GB ram, DVD 720x480 clip

Vinverse seems to consist only of Expr+MakeDiff and therefore has the biggest speedup of ~22%

I have notice a new problem with Python 3.7.4 installer that's affecting vs installer. When I'm doing a clean install, if I choose "install now" in python installer, the default installation path would be something like "users\username\appdata\roaming\...", and the default installation path for the vs installer would be "users\username\appdata\local\programs\vapoursynth". But if I choose "custom installation" in python installer, its installation path would be changed to "c:\program files\python37", and the vs installer would also be changed to "c:\program files\vapoursynth".

Not that I know of. Avisynth compatiblity should work though.

Only on Windows, or should this also work on Linux and I simply don't know how to get it working?

why is vsscript.dll required to be placed in the same folder with vspipe.exe for the new release?

I stopped putting a copy of vsscript.dll in the system directory in R46. Putting things into the system directory is bad.

Changing the vsscript api to match the style of the rest of vs so importing it becomes trivial is on my todo list and will fix it. Some day.

Is there a detailed user guide? Of course, I am happy to use QTGMC and other plugins, but there is very little knowledge and information.
