jumping

Hi I'm sorta new to brickfilming and I don't know how to make a minifigure jump.I've read the technique on stop motion central.But, what about minifigs with hair? You can't use the pole technique on that.

Also, If I use chroma keying if your looking up at the minifigure, it will cut off the bottom of the feet.These aren't the circumstances, but just in case.
