KDEnlive - Export not possible, Python error

Morning all,

i am trying to export an edited video from KDEnlive.
After fixing an issue that pip3 was missing i ran in another problem which i hve no idea how to solve it.

So far everything goes fine, but if i come to exporting the video, i am getting this error:


Klicking ok brings me to the export settings, whenever i hit the reload button, the python error appears again:


I fixed that issue also by installing the python setuptools, but there is still this error which doesnt go away, even after hitting the “instal dependencies” button:

I have tried to install it also via “pip install opentimelineio” in a terminal, but it throws a similar error:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for opentimelineio
Failed to build opentimelineio
ERROR: Could not build wheels for opentimelineio, which is required to install pyproject.toml-based projects

Any idea how to get this resolved would be appreciated

There was a huge python update today.

Also, opentimelineio is in the repos and up-to-date, including dependencies.

Why would you want to build it yourself?

sudo pacman -Syu opentimelineio …and reboot.


Both has been installed. There is no update waiting and opentimelineio was installed exactly as you described.

Error persists

Hello, if what you are looking for is to export the project in the sense of rendering, that is, converting it to video format, what you have to do is go to project/render.
