Camera Auto Focus Between Text Layers
I’m looking to have the camera autofocus between two text layers.
The camera is dollying forward slowly and I don’t want to key-frame constantly (not linear movement either).
This is what I have so far which works for piece one.Still need the camera to then focus smoothly between the two text layers.
Thanks,

target = thisComp.layer("Productions");
v1 = target.toWorld(target.anchorPoint) - toWorld([0,0,0]);
v2 = toWorldVec([0,0,1]);
dot(v1,v2) -

So now I’ve got two sliders each with the auto focus on, if I type a or b the camera focus switches between the two layers.
I need to key-frame the switch and it needs to be gradual.
How do I do that? Inexperienced expressionist here.
a = thisComp.layer("Camera Focus").effect("Title Focus")("Slider")
b = thisComp.layer("Camera Focus").effect("Productions Focus")("Slider") -
Add another slider (to the camera itself in below example) that changes the value from a to b:
c = effect("Slider Control")("Slider");
f = linear(c, 0, 100, a,b)
(f = focus)This code goes below your existing code.
Then you can animate the slider control to change the value smoothly.

This worked beautifully! Final expression on the camera focus distance. Thank you so much.
a = thisComp.layer("Camera Focus").effect("Title Focus")("Slider")
b = thisComp.layer("Camera Focus").effect("Productions Focus")("Slider")c = thisComp.layer("Camera Focus").effect("Slider Control")("Slider");
f = linear(c, 0, 100, a,b)
