GH4 video judder/strobing - a solution

I am curious if you found out what the issue was since creating this thread?

One thing that comes to my mind is that the video player you were using (and that the camera itself is using) doesn't play 24 fps video well on a 60Hz monitor. 24 is not a factor of 60, unlike 30, which would explain why 30 fps video appeared a lot smoother.

You said that the 24 fps footage from other gear was fine, but it wasn't clear if everything else was the same (computer, player, codec).

More people should read this article (I posted this link in my previous reply too):

It's not specific to GH4 and whoever says that, is not telling the truth. I had same problem with Canon 7D when shooting at 24 fps (23.97), and many other cameras have same "problem".

Just a little quote from there that should make anyone interested in reading and learning about judder issue:

"...You’re probably aware that most Hollywood movies that you see at the cinema as shot in either 24p or 25p as in 25 frames of film per second. So you’re probably wondering why all those movies look great at the cinema and don’t have the so-called ‘judder’ or ‘flicker/strobe’ effects that your progressive scan camcorder appears to be riddled with. The simple answer is because Hollywood production companies hire in a professional DoP (Director of Photography) and pay him/her a colossal amount of money to get it right. The DoP knows exactly how to ‘Block and Stage’ every shot in such a way that prevents any judder or flicker in the final footage..."
