When you customize your own role's action/expression in Adobe Flash, you can follow the tips below: 


1 The role should be in the center of canvas

2 The width and height of the role action/expression should be nearly the same

3 The duration of the scene should be the same as the role action/expression duration


When you drag the playhead, the expression will play correspondently. 



Note: Generally, the role action/expression (*gif) should be transparent.
