First, I followed Video Copilot’s tutorial on syncing an animation to audio. That provided me with this expression:
A = lowest average value in your audio waveform graph
B = highest average value in your audio waveform graph
C = Value to use instead of A
D = Value to use instead of B
This worked. But the animation turns out quite harsh, so I wanted to smooth it out.
Then I found this:
2 would be the number of seconds it’s looking at;
And 5 is the number of frames the smoothing extends to.
So I tried to do it this way:
It doesn’t work properly, because I’m trying to make a graphic in the composition, change scale with the music. It’s set to 60,100 in the first expression because I want the minimum size to be 60 and the maximum, 100.
But when I add that smooth expression below it, the graphic shrinks, I can see in the scale parameter, that’s using little sizes like 1% instead of the 60-100 I want.
What am I missing?
