Scripting through external console on windows 10

Hi,

I have been trying to just run one of the example scripts but i just get:
Unable to find module DaVinciResolveScript from $PYTHONPATH - trying default locations
Traceback (most recent call last):
File "C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\Developer\Scripting\Examples\1_sorted_timeline_from_folder.py", line 31, in <module>
projectManager = resolve.GetProjectManager()
^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'GetProjectManager'

however i have followed the readme to set the enviroment variables so i am not sure why it is not finding the python - any help would be appreciated

I've ran into numerous issues using python inside resolve.
My recommendation would be external python.

- Use a IDE of your choice (PyCharm, Thonny...)
- make sure resolve is started and a project is opened
- Use the loader provided in the link (or write your own)
- run script inside the IDE
- do your stuff

Interesting! Is this possible with LUA too?

Yes. Lua is automatically installed by the Resolve installer, but for internal scripting also. I'm not sure if one can run the interpreter from outside of Resolve. I've never tried to actually find it on the file system.

Here, just use this to make a resolve instance for external scripting in Windows. It's straight from the sample scripts that come with Resolve. You can paste this in your Python interpreter, but you can't go higher than Python 3.6:

Code: Select all

import imp

library = 'C:\\Program Files\\Blackmagic Design\\DaVinci Resolve\\fusionscript.dll'
bmd = imp.load_dynamic('fusionscript', library)
resolve = bmd.scriptapp('Resolve')

Yes, the executable for the interpreter is called "fuscript" and it can run LuaJIT or Python.

Code: Select all

Usage: fuscript [opts] <script> [args]
   -i                   - Enter interactive mode
   -v                   - Print version information
   -s                   - Run as script server
   -S                   - Run as script server with no timeout
   -p [appname]         - Ping script apps
   -P [appname]         - Ping script apps (longer timeout)
   -q                   - Be quiet
   -b                   - Run with commandline debugger
   -l <lang>            - Explicitly set language, from:
      lua
      py2 or python2
      py3 or python3
   -x <string>          - Execute string

Wow... thanks for the insight Roger. This might change the way I am working so far. I have a rather long LUA script running inside resolve, which can drop the playback performance depending on what it's doing. Maybe I can split it into different threads with external LUAJIT.
