Re: GH4 video judder/strobing - a solution

To be honest I haven't noticed anything disturbing on the camera's lcd while filming but I wasn't really looking for it so I can't say for sure that it does or doesn't judder, all I can say is I haven't noticed.

I just sold my GH4 and went with lighter Panasonic GX85. So after reading this I've looked at 24p footage from the GH4 and from the GX85 on my 60p HP professional monitor, and to my surprise there is no judder on any of the footage. I don't have anything like sports or very fast movements but footage with my kids playing is looking smooth from both cameras.

However, I was shocked to see the outdoor 30p footage from the GX85 does have some stuttering. GH4 30p footage that I have looks smooth. How can that be ? 30p footage I always shoot at 1/60. It does stutter from time to time. Playing on TV player, or nvidia shield media center, also stutters.

So what I did was playing the same portion of the scene over and over again in VLC and I noticed something strange: the stutter happens randomly, never on the exact same frames, and once in a while it plays without stuttering at all.

That is unexpected, no stutter or judder on 24p on GH4 (C4K) or GX85 footage but stutter on GX85 30p.

I'm thinking you should also try my experiment with your GH4 video and see if it stutters randomly or on same frames.
