AFAIK, there is no autofocus system currently on the market that is able to track a moving subject continuously for video use.
If you set up your GH4 properly and use AFF, It does quite well.
Saturday I shot a Grand Prix Equestrian Event and only lost focus once on a very large and fast course.
The horse and rider were completly out of sight several times each run and I did 15 before going home.
My DSLM has excellant contiuous AF and will shoot for hours unattended.
It also has pleanty of DOF.
I've had/looked at the latest CamCorders and none are a well suited for my use.
