How to automate a parameter using length of a media source -- or otherwise?

[AND]

Hello,

I'm new to OBS and trying to set up a simple scene:

- Recording / stream starts, the scene is completely black (scene -> colour correction filter -> brightness at minimum)
- I play a media source (audio) of 15 seconds of length
- as the audio source plays (i.e. its remaining length shortens with time) I want the scene's brightness setting to slide back to the normal value (the middle).

Is this possible to be done somehow? Can I somehow automate the brightness with the remaining play time of the media source? Or can I automate it in another fashion i.e. with a plugin or a script so that I achieve the same effect?

Thanks,
- A

Alright, found my own solution:

I used Advanced Scene Switcher with fade in macros, as described here: https://github.com/WarmUpTill/Scene...nd-stop-recording-with-fade-from-and-to-black
