So did you think you also seen this in the VF before you updated the firmware.
I see firmware 2.2 and 2.3 mine is V2.1

It's hard to know if what I'm talking about is what you're talking about. I did get the feel that motion didn't look as smooth when recording 4K, but only on the LCD and vf. As recorded it was fine. I'm out so can't check what firmware my GH4 is currently at.

Chris, I'm wrong I'm sure, I know nothing of 4K recording and playback but about the LCD not being able to keep up, it could be this, The camera VF is as far as I see perfect in all other recording modes.

No,.. 4K playback just looks a wee bit different to my HD clips. Perhaps this is what 4K looks like on an ordinary HDTV, I don't know.

I used OIS but yes, if the camera is fixed I see nothing, but if I pan the GH4 I see it again in the VF, funny, it doesn't look just as bad in the LCD, but as we said in an earlier post if the camera moves its like recording in 1/25 shutter speed instead of 1/50.

Thank you.

:) I know, it isn't easy.
Thank you.

I think it's just the normal stutter you get at 25P when you pan ..nothing to worry about!!

So, it could be just VF LCD lag in 4K recording all along.

Thank you, good to know. :)

Keep in mind that panning in 4K will have a greater tendency to judder (strange lag effect when you pan at certain speeds) than 2K or HD, everything else being equal (shutter speed, aperture, lens, etc)...

Our shooting styles have had to evolve a bit, just like they did when we all went from shooting SD to HD.

Thanks Tim, are you refering to the recorded 4K files or just what you see in the VF?
