Re: GH4 video judder/strobing - a solution

...thanks Pete for trying C4K, reassuring that it's just an issue at my end.

Though I definitely see occasional judders on the camera's LCD, when panning using either C4K or 4K, at 24fps.  As to the results on a FHD monitor, I'm not sure the judders are in the same place, and could be due to my i7 quad core (and graphics card), not being up to it.

I certainly cannot play 4K, though this at present wouldn't be required. I'm placing 4K into a FHD timeline, and then rendering it, before viewing.  It should play smooth, though again maybe my Mac's spec isn't up to the bit rate or somesuch.

The odd thing is if I use 29.97fps all is very very smooth, including pans, and 29.97fps has the same bitrate over time (although as there are more frames per sec, each frame will contain slightly less info than 24fps).

I shall to return to this in a 5-6 days, other commitments at present.

In anycase when running smooth, the footage looks incredible; settling on these settings - not too flat - which is great in the current UK overcast conditions, skys hold-up well, and grade well, the output isn't too far off what I require.  I prefer not to push the output around too much in post afterwards...
