GH4 video judder/strobing - a solution

24 or 25 into 60 doesn't go

Hi Andy, I'm coming to the conclusion the stutter/judder I'm seeing on pans is 3:2 pulldown.

When I play 24fps footage at 30fps, it runs smooth (obviously this isn't a solution as footage length decreases), but in this case the 30fps pulldown on a 60Hz display is an even 2:2.

As you have been using 25fps on 60Hz displays, I'm sure you're used to seeing 3:2 pulldown effects, so I'm wondering if you think the juddering is a particular problem of the GH4?

Unfortunately I haven't got access at present to a 120Hz display which would clear this matter up once and for all!  I guess all those who find 24fps pans smooth probably do have 120Hz displays, or are viewing it on DCPs!
