strobe expression

[Filip Vandueren]

Hey Barend,


frequency=3; // times per second
burstlength=3; // in frames

t=time%(1/frequency);

t

change the lensflare expression to this, to factor in the Intensity of the light:


l=thisComp.layer("Light 1");
c=thisComp.activeCamera;
vec1=normalize(l.transform.position - c.position);
vec2=l.toWorld([0,0,-1]) - l.position;

dotProduct = dot(vec2, vec1);

linear(dotProduct,-1,1,0,1) * value * l.intensity/100;

Hey Filip,

It seems like the ‘strobe’ expression is incomplete in the post, or am I missing something?

I just returns a value of 0.

Thanks,

Oops, there’s a lesser than character in there, that screws up the HTML formatting, check your email of the previous post for the correct version.

or this one should work online !but not in your email!


frequency=3; // times per second
burstlength=3; // in frames

t=time%(1/frequency);

t < framesToTime(burstlength) ? 100 : 0;
