but didn't find method either in sdk guide or in examples.

hi hohokyo!

welcome forum!

 

there few ways of getting layer's pixels (any layer in comp, including 1 effect on).

two of discussed here:

the concept of sampling times other current referred "wide_time", , there;s flag set work.

in both methods can specify time wish sample, can access frame in sequence @ time.

for both these methods must have layer param, pointing @ layer wish check (you can set point self default).

that param can hidden user needs not bothered it.

 

there third way, involves accessing source footage item of layer , rendering it, far less recommended, doesn't let ae know in advance you're do, ae doesn't cache these frames.

the advantage of method on other 2 can called @ time, while first 2 can give images during render call.

 

that's it.
