Using Python and Expanding Resolve’s Functionality

Joey,

Firstly, thank you for that great insight.
When I heard there will be Python support in Resolve, I was so excited and started to learn it. I learn some fundementals and got familiar with syntax but since I’m really new in this subject I didn’t get it how to set up the scripting function in Resolve. There was a video about that in YouTube but I really don’t get it..

I think Python scripting opens new horizons in terms of automation. My first idea was to build a script for exporting clips which going to VFX. I’m working myself mostly and I do a lot of online editing work. It’s so annoying to write all these timecodes, than mark them and give export. I want write a script I can write timecodes in it and let the Resolve do the rest…

I will definitely check the the learning resources you choose… It came a little abstract while I was learning (I used Lynda a lot) now I can open and try things in it. I hope that will help to my learning curve. Please please enlight us about Python and possibilities of it…

Thanks! yea im really exited to see the API mature and add more functionality. I’m still early into learning python myself – so I like to lean heavily on looking at examples and taking bits and pieces from them.

In that examples folder that comes with resolve – there’s actually a script that adds timelines to the render queue. that may be a good jumping off point for what you have in mind. Looking at the API reference – you can adjust mark in and mark out points of renders in script.

It would be great if they fully built out the api to all color controls then it would really open up the ability to build custom control surfaces beyond having to use screen size dependent mouse controlling software.

Yea I would love that. The more things that are scriptable, the better!

Is there any reason that I am unable to add multiple paths to the environment variable? My box is much more simplified

separate the paths with semicolons when you first enter it. Once you do that, if you click “edit” – then it will show you the multiple path dialog.

Wonderful! Thank you so much for this. Would also love additional insights that cover setup for Mac and Linux.

Thanks!

On mac or linux you need to set the environment variables in your .profile file.
so in a text editor, open ~/.profile

and on mac add:

export RESOLVE_SCRIPT_API=”/Library/Application Support/Blackmagic Design/DaVinci Resolve/Developer/Scripting/”
export RESOLVE_SCRIPT_LIB=”/Applications/DaVinci Resolve/DaVinci Resolve.app/Contents/Libraries/Fusion/fusionscript.so”
export PYTHONPATH=”$PYTHONPATH:$RESOLVE_SCRIPT_API/Modules/”

then log off and log back on.

on linux, it would be:

export RESOLVE_SCRIPT_API=”/opt/resolve/Developer/Scripting/”
export RESOLVE_SCRIPT_LIB=”/opt/resolve/libs/Fusion/fusionscript.so”
export PYTHONPATH=”$PYTHONPATH:$RESOLVE_SCRIPT_API/Modules/”

if you didn’t already have a ~/.profile file – make sure you make it executable after creating it by running:

chmod a+x ~/.profile

(note – i haven’t tested this. this is just based on the paths listed in the readme.txt file)

Hey Everyone – just a quick note, a member reached out to me having trouble with the script example. Turns out having eomji characters in your frame.io profile or comment was causing errors – so I’ve updated the download link to a new version that strips those characters out.

Excellent! Will give this a shot!

Hey guys – one more quick note – I made an error in this insight and said to install the latest version of Python (which is 3.7) – Resolve actually is expecting 3.6, so if you are going to use python3 – Install the latest 3.6 version, not the latest 3.7

This Insight has been updated with a new version of the Python script which can handle Replies to comments in Frame.io.

Hi !

Sorry could you explain a little bit more how to set the environment variables on MAC ? I could not find any .profile file…

Thank you,
E

If you don’t have a .profile file (in your user’s home directory) – you can just create one. (run touch ~/.profile)

then you can open it in a text editor and add the export lines to set the envirnoment variables.

Has anyone had issues importing Tkinter? I’m on 3.6.8 and am getting ModuleNotFound errors calling it out in the console. Thanks!
