Camera movement with Sound Keys
I’m trying to move my camera along the Z axis at a constant pace, but I want it to speed up speed with the bass from Sound Keys. I found that using integrate instead of falloff in Sound Keys worked to an extent, but the speedup ends too abruptly without a falloff. I imagine this can be solved with expressions, but I don’t know how.
I.E. I want a base speed + speed from Sound Keys frames.
Any help would be much appreciated. <3

Something like this, probably:
spd = 100;
zOffset = spd*time + thisComp.layer(“Sound Keys”).effect(“Sound Keys”)(“Output 1”);
value + [0,0,zOffset]Dan

I was using a similar expression, but it only works when using “Integrate” falloff in soundkeys, even though I want the ramping down effect of Linear or Exponential falloffs. Without Integrate, the expression always moves the camera in reverse after the sound stops or drops off for a moment.
Thank you for the reply, by the way! I’m hoping we can solve this issue.

Though, I would like to add that I have the dimensions all separated, so this is the expression I’m using. I don’t think that would be the cause of the issue though.
spd = 100;
z = spd*time + thisComp.layer(“Sound Keys”).effect(“Sound Keys”)(“Output 1”);
value + z -
I was assuming you were using “None (integrate)”. It’s a lot trickier if you have to devise your own integrate/easing function.

Damn..
I’ll use integrate if we can find a way to ease it. Possibly setting all the keyframes from Soundkeys output to ease out? -
I feel like setting the soundkey keyframes to ease out helped a little bit (Might be convincing myself though?), but I’d still like it to falloff over a longer period of time. Hmn.. I might just try to hide the sharp slowdown with blurs and glitch effects, if we can’t find a way. Of course though, I thank you for the help. ?
