Loopable Particle Animations

Does anyone know how to configure the particle effects to make a loopable animation? I am trying to make animations of fire, sparks, rain, and waves to use as continuous, looping, backgrounds in videos. I think I have looked in all the usual places on the Internet and I can’t find any information on this.

Thanks!

this has been asked before

there is no simple answer, and I reccomended rendering to an animation, and using the sequence editior to blend the ends of the animation into it’s middle

(see http://www.geocities.com/z3r0_d/files/seamlessLoopAnim.png )

err see that other thread at https://blenderartists.org/forum/viewtopic.php?t=10789&highlight=sequence

Thanks!
