Place only one of the object that will be moving and move it to somewhere where it cannot be seen by the rider. Important: Go in the object's properties menu to Advanced Physics and turn off the World Gravity for this object.
Now place an emitter at the position, where the objects begin to move. Go to its properties menu and choose the recently placed object as the emitting object. Make sure the Checkbox „Emit Physics Object“ (the exact words may vary) is checked. Now adjust the Starting Velocity and the Emit-Interval in such a way, that it mostly resembles your OPE animation. You can also change the value of the maximum number of objects being emitted, before old ones are getting destroyed, if you like to. It may prevent some bugs, for instance maybe you will want to increase the number, because the player could see, when the objects were being destroyed again.
I hope this helps ;)
Edit: Oh, and set the spawn radius of the Emitter to 0, so that all objects will have the same starting position (otherwise they would randomly spawn within the spawn radius)
