How to shutdown the computer automatically after a render

Hi

Resolve 17 has the option for a post-render script (Render Settings > Advanced > Trigger Script at end of render job). You can queue up your render jobs, add a script to the last job in the queue and use that script to set your system to sleep/shutdown/spin-down drives, or even send an email notification so someone can push a button.

Please refer to the What's New in Resolve 17 document (starting page 349)

So for people on Windows 10
(I'm sure there are other commands, I don't know, but this works for me) :

1) Create a LUA script with this code in it (just use the notepad) :

Code: Select all

manager = resolve:GetProjectManager()
manager:SaveProject()
strProgram = '"C:\\Windows\\System32\\shutdown.exe" /s /t 00'
os.execute(strProgram)

2) Put the file in C:\ProgramData\Blackmagic Design\DaVinci Resolve\Fusion\Scripts\Deliver - and call it "Shutdown.lua" for example

The first two lines will make Resolve save your project, then it will shut down the computer directly.
/t 00 is the time before the shutting down process (in seconds). You can delay it by giving a duration in seconds.

You can find all the other options here : https://docs.microsoft.com/en-us/window ... s/shutdown

I don't know the commands for Linux or MacOS, but I'm sure it can be found very easily.

I'm sure there are tons of other possibilities, like playing an audio notification, etc. anything that can be triggered by a script.

PS.
Don't test it like I did, with all my applications opened and work not saved

Working fine thanx.
Btw does this close davinci resolve AND shutdown the pc?

What I've done for years is ballpark-guess how long the render will take, then set an OS timer that adds another hour to that time (for safety) and shuts down the system. If Resolve is finished, it will allow the OS to safely exit the program and shut down, provided you have nothing else running (like an unsaved document in the background).

This particular one is just sending a signal to shut down the whole computer, regardless of what's oppened (the same way you would do from the start menu).

I added two lines at the beginning of the code. It will save your current project (in Resolve) before shutting down the computer.

You can try it, by changing 00 by 3600, so it would wait one hour before shutting down (I didn't test anything else than the immediate shut down)

I added two lines to the code so the project is saved beforehand.

Code: Select all

manager = resolve:GetProjectManager()
manager:SaveProject()
strProgram = '"C:\\Windows\\System32\\shutdown.exe" /s /t 00'
os.execute(strProgram)

I added two lines to the code so the project is saved beforehand.

Code: Select all

manager = resolve:GetProjectManager()
manager:SaveProject()
strProgram = '"C:\\Windows\\System32\\shutdown.exe" /s /t 00'
os.execute(strProgram)

If the timeout period is greater than 0, the /f parameter is implied.
/f Forces running applications to close without warning users.

The best option might be to change the line to strProgram = '"C:\\Windows\\System32\\shutdown.exe" /s /t 30'
so that it starts the shutdown program with 30 second delay.
Then add a line to close Resolve

Code: Select all

Quit()

This will end the script and close Resolve but won't stop the running shutdown program which will shut down after resolve is closed.

good stuff - very useful
better than using a shortcut C:\Windows\System32\shutdown.exe -s -t xx and guessing for xx,
that I've used in the past, like MarC.
Speed Warp etc can add varying 'extra' time to the render so....
Your method is 'keyed' by Resolve finishing render - nice.
Thanks!
(and oh, the file *does* need to be .lua - not .txt for Resolve to recognize it, as you suggested)

Very useful thanks!

Just adding that you can also have a "hibernate" script by doing "shutdown /h" instead:

Code: Select all

manager = resolve:GetProjectManager()
manager:SaveProject()
strProgram = '"C:\\Windows\\System32\\shutdown.exe" /h'
os.execute(strProgram)


(This requires to have hibernate enabled in Windows.)

Cheers!

Very nice! Is there also a script like this for Mac?

It should be equally simple to do for a POSIX OS.
Just google scripting for Mac.
It is worth learning basic scripting
