Modifying clip’s opacity with expressions/modifiers
Hi
So I would like to use a random expression or a shake modifier to control the opacity of a clip (in order to randomly change its opacity over time without using keyframes). As far as I know there is no way to do that in the Edit page or Color page so I have to open the respective clip in the Fusion page.
Now, I could add a Brightness/Contrast node between the MediaIn and MediaOut nodes and assign the random expression or the shake modifier to the Gain parameter of the Brightness/Contrast node but I would like to know if there’s a simpler/quicker method to accomplish this.
Cheers!

Hey mate, I would suggest you check this page: https://another-davinci-resolve-blog.blogspot.com/2021/03/davinci-resolve-expressions.html
If you search for random, you’ll find a couple of expressions that should work for you, especially this one: :randomseed(floor(time/6)) ; return random()
If you want a tutorial on how to use this expression, I found this video: https://www.youtube.com/watch?v=n6K4n9WgmooHope this helps!
