I have a questions about keyframes. I used the CC Lens effect and I synced it to some keyframes from "Sound Keys" (Plugin which creates keyframes from music). But everytime it hits the beat, the lens-size goes up, but I want it to go down. Because when there is no beat, there is nothing to see, because the lens is so small. I want it the other way round, that the lens is small, when it hits the beat. I guess I have to somehow flip the keyframes, that all the low values are high and all high values are low? Is there an effect for this, or do I have to write it in the expression?
You need to specify in SoundKeys what your output range should be. There are options within the plugin that let you define the values that you want the keys to produce. If all else fails, you can just put an expression on your property:
So instead of having keys that go from 0 to 100 (or whatever your range is), they go from 0 to -100.
As already suggested, use the custom output range option and simply reverse the values.
