How to animate in point and out point of layer with expressions?

[mehmet turhan]

I’m trying to animate the in opacity and out opacity of a layer with just an expression

linear(time,inPoint, inPoint+.5, 0, 100)

linear(time,outPoint+.5, outPoint, 100, 0)

This is what I did. It seems the second line always overwrites the first one. How would you animate layer appearing with opacity and disappearing with opacity with just expressions?

[Filip Vandueren]

if (time <= inPoint+0.5) {
    output = linear(time,inPoint, inPoint+.5, 0, 100);
} else {
    output = linear(time,outPoint+.5, outPoint, 100, 0);
}
output;

Simple modification.

<pre data-placeholder=””>

if (time <= inPoint+0.5) { output = linear(time,inPoint, inPoint+.5, 0, 100);

} else {

output = linear(time,outPoint-.5, outPoint, 100, 0); // just replace + with –

}

output;

Thanks! It makes sense and worked perfectly!
