changing opacity at specific time

[Kevin Camp]

how about something like this:

Math.round(time%1)*100

really nice,

but the 100 is not needed at the end. What i am not understanding. I have a movie with 15fps. That means time = 1 when i am at frame 15.

When i am at frame 1 it means in seconds 0,066666

The reason i am asking, what when i wand every 4 (3,75) frame changing the opacity, so that i get 250ms?

it wont work with Math.round(time%0.4)

thank you

i don’t think you can use a decimal with a modulus… time%0.4 is like stay you want the remainder of time*4… there is no remainder in that equation.

try converting time from seconds to frames. in later versions of ae you can use timeToFrames(). in earlier version you could use time/thisComp.frameDuration

maybe an expression like this:

if(timeToFrames(time)%8<4) 0 else 100

Thanks mate,

its working fine,

very clever one:
if(timeToFrames(time)%8<4)

i would have done this in this way:

if(timeToFrames(time)%4==0)
and would forget, that than the first frame (time= 0) woul also give true back

For me its done . Next i will try to change the Modulus Value, so that the time between the switches are getting closer and closer 😉

Thank you again so much for your help, and insane fast replies!

Hi @ all,

i am now here to add some changes to my script, but i have new questions.

var moduloConst = 32;
if(timeToFrames(time)%moduloConst

1) It’s weired, adding
moduloConst = moduloConst/2
lets transform.opacity gets filled with the “moduloConst” value. (In this case 32)

would be nice if someone could give me a hint.
