How to change the default composition duration when i open illustrator file as "composition"

[David_Mk]

I am trying to open the layered adobe illustrator file as a "composition-retain layer size" in after affects, however every time the composition duration is 15 seconds, is there a way to change it?

Thanks!

[P.M.B]

On the menu bar at the top of the screen open the Composition Setting in the Composition Menu, or hit CTRL-K.

Then just set the duration to whatever you want & hit OK.

If your making the composition longer you'll need to adjust the workspace so it covers the entire composition

After Effects remembers the last composition you created. Create a new comp that is 38 seconds and the next new comp or comp from selected will be 38 seconds unless the selected item is footage (a movie or image sequence).
