Re: 60hz monitors are capable of smooth 24p playback

I tried to read a lot of this thread but it all seems to be a general lack of understanding about 24p and how to shoot with it.

Basically DO NOT PAN with 24p!

If you watch movies they rarely pan.  Panning is rotating the camera from a fixed position.  In cinema they move the camera, not rotate only.  24 frames per second is just too slow to keep up with a panning style motion and make it look smooth unless you go super slow.

You have to learn how to film in 24p.  It will tell you what works and what does not work.  If you see judder then it did not work and you need to analyze what you might be doing wrong.

The classic approach is to not move the camera unless the subject of your shooting is moving.  By moving the camera with the subject, the subsequent background judder is not "noticed" by the viewer.  It is still there, you just do not concentrate on it.  Shallow DOF helps a lot as well.

Hope this helps clear up some of the incorrect information in this thread.  Good luck and it is not the fault of the GH4.
