Resolve requirements​

Resolve uses a separate Python interpreter (it does not come with Python itself). The interpreter needs to have installed PySide2 (or PySide6 if on MacOS) and OpenTimelineIO dependencies for Ayon to work correctly. Bellow you can find instructions on how to install them into an installed Python of your choice.

• Resolve 19 - our recommended version range Python 3.9.x (in complience with Ayon), also been tested with Python 3.10.x

• Resolve 18 - our recommended version range Python 3.9.x (in complience with Ayon)

• Resolve 17 - our recommended version Python 3.6.2

Python and Resolve

Configuring settings for Python home directory​

To be able to run python in Resolve you need to set RESOLVE_PYTHON3_HOME environment variable to the directory path of your Python interpreter version.

Open your server Studio settings and go to Resolve under Applications and Tools settings ayon+settings://applications/applications/resolve. Here you can add the path to the Environment section.

Installing Python dependencies​

PySide2 or PySide6​

AYON is using its own window widget inside Resolve, for that reason PySide2 (or PySide6 if on MacOS) has to be installed into the python.

• Windows

  cd <a path you had set to RESOLVE_PYTHON3_HOME>
  python.exe -m pip install PySide2

• Linux

  cd <a path you had set to RESOLVE_PYTHON3_HOME>
  python3 -m pip install PySide2

• Mac OS

  cd <a path you had set to RESOLVE_PYTHON3_HOME>
  python3 -m pip install PySide6

OpenTimelineIO​

AYON is using OpenTimelineIO for editorial publishing. OpenTimelineIO has to be installed into the Resolve Python environment. Tested versions:

• Resolve 19 - OpenColorIO 0.17.0 with Python 3.9.x or Python 3.10.x

• Resolve 18 - OpenColorIO 0.17.0 with Python 3.9.x

• Resolve 17 - OpenColorIO 0.13.0 with Python 3.6.2 (see special build instruction below)

• Windows

  cd <path to RESOLVE_PYTHON3_HOME>
  python.exe -m pip install OpenTimelineIO

• Linux

  cd <a path you had set to RESOLVE_PYTHON3_HOME>
  python3 -m pip install OpenTimelineIO

• Mac OS

  cd <a path you had set to RESOLVE_PYTHON3_HOME>
  python3 -m pip install OpenTimelineIO

Debugging if Python is not working in Resolve​

Set Resolve's Fusion settings for Python 3 interpreter​

In case Resolve is not showing Ayon menu, please have a look into Resolve's console and click to Py3 tab. If it is not working then Python is not correctly connected to Resolve. One of the reasons might be that Fusion is not set to use Python 3.6 interpreter.

As it is shown in below picture you have to go to Fusion Tab and then in Fusion menu find Fusion Settings. Go to Fusion/Script and find Default Python Version and switch to Python 3.6

Custom DaVinci Resolve Python 3.x interpreter​

In the Studio Settings / Applications / Resolve section, you can change the environment variables to configure a custom python interpreter.

e.g. An example of a possible configuration, or use hard-coded and write it in the environment configuration.

{
    "RESOLVE_UTILITY_SCRIPTS_SOURCE_DIR": [],
    "RESOLVE_PYTHON3_HOME": {
        "windows": "{CUSTOM_RESOLVE_PYTHON_HOME}",
        "darwin": "{CUSTOM_RESOLVE_PYTHON_HOME}",
        "linux": "{CUSTOM_RESOLVE_PYTHON_HOME}"
    }
}

Set your python 3.x interpreter directory to the environment variable CUSTOM_RESOLVE_PYTHON_HOME.

Next, you'll need to use your custom python interpreter to install some of the necessary packages

1. python -m pip install PySide2

2. python -m pip install OpenTimelineIO

Enable Scripting​

In Resolve go to DaVinci Resolve > Preferences > System > General. Set External scripting using to Local.
