How to get current frame in expressions.
I am trying to make the opacity of a video 0 on every even frame, and 100 on every odd. I have added an expression on the opacity of the video that looks like this:
d = thisComp.frameDuration;
if (d%2==0){
opacity = 0;
}else{
opacity = 100;
}but this does not change the opacity of the video at any time.
how would I get the current frame number, then test every frame to see if it is even or odd and adjust the opacity accordingly.

you could do this (where 25 is fps):
(time * 25) % 2 == 0 -
For some reason, I get a rounding problem, where once in a while 2 frames get the same restult.
This expression works better for me:
C=((time*25)/2)-(Math.round((time*25)/2));
if (C==0)
{
100
}
else
{
0
}
