I have a animation on Proanumator and I wish to control the specific frame where the animation start, because the proyect have an animation of AE camera and the object is supouse to start moving when the camera stop.
That's really not a problem. You can position the point between the poses and transition down to the exact frame you want. Simply look for the three rectangles that look like they have two mountains in them. Click on the middle one to zoom in as far as you need, to zoom in on the part of the timeline you want. The motion in the transition begins at that exact moment. The ease controls will affect the ramp up and ramp down speed for the transition. Zoom out by clicking on the first set of mountains.
