Auto fade in/out layers BUT with a defined blinking effect

[Dan Ebberts]

This should be close:


if (time < inPoint || time > outPoint){
f = 0;
}else if (time < inPoint+outPoint/2){
f = timeToFrames(time - inPoint);
}else{
f = timeToFrames(outPoint - time);
}
switch(f){
case 0:
case 2:
case 4:
case 6:
0;
break;
case 1:
25;
break;
case 3:
50;
break;
case 5:
75;
break;
case 7:
100;
break;
default:
100;
break;
}

Dan you’re a frikkin genius. You’ve solved it yet again.

I understand the top half but If you’ve got a sec, could you briefly explain whats happening from ‘switch(f){‘ onwards? What is switch, break and case?

Thank you!

This explains it better than I could:

i’ll have a browse thanks ☺

On further play, It’s behaving a little odd. I’ve duplicated the text and adjusted the length and some of them work as expected and some just cut straight off… if i extend the time of the ones that cut off to a longer then they do the flicker… its seems random as to if they work or not.

Thanks

Sorry–rookie mistake. Try this one:


if (time < inPoint || time > outPoint){
f = 0;
}else if (time < (inPoint+outPoint)/2){
f = timeToFrames(time - inPoint);
}else{
f = timeToFrames(outPoint - time);
}
switch(f){
case 0:
case 2:
case 4:
case 6:
0;
break;
case 1:
25;
break;
case 3:
50;
break;
case 5:
75;
break;
case 7:
100;
break;
default:
100;
break;
}

amazing that seem to have got it, thank you!

As if you haven’t help me enough, i’d like to try push it a little:

Could this be adapted so that it could be applied to text’s ‘animator’ property so each letter or word (you can choose) would flicker on in sequence or randomly (also choose). Ideally Id like to have a text layer that animates on/off based on the inPoint and outPoint (as it does so beautifully now) except there for would expression controls that allow you to change weather it flickers on as a whole, per word or per letter and also weather each word/letter flickers on in sequence or randomly.

Would this be terribly complicated?

Thanks again for your help Dan, really appreciated.

Hi Dan, i just wanted to share with you the project I just completed that used you expression. You saved me so much time, thank you:
