200Mbs all-I is highly variable bitrate. Try shooting something with lots of random and sharp motion in frame. Why are you shooting with all-I anyway? It is the worst codec in GH4. 

Abnormal behaviour of me or of my lens?  Or both :)
 
I have found now so many people with this same issue that maybe it is time now to contact Panasonic. Thanks for link.

I dont know if my new 14-140 mk2 lens is broken but the stabilization in video mode is bad. It smooths big movements but leaves fast "micro jitter" or vibration which looks bad in big screen.
 
When just looking through EVF image is stable but when I start recording image starts to vibrate and wobble.
 
I downloaded my tests to Vimeo:

I think it must be broken. Compared to my old 14-42 it vibrates very nasty.
What do do think? Is this normal?  I would be very thankful if someone with 14-140mm could test this too.

GH4 CODEC INFORMATION:
(GH3 1080P has profile 4.2 cbr about 50Mbs)
GH4 1080P has profile 5.0 vbr about 80Mbs max 106Mbs
GH4 4k has profile 5.1 vbr about 80Mbs max 106Mbs
Bitrate bits/pixel/frame: GH3 50P-0.457 GH4 60P-0.652 GH4 4k 30P-0.313
GH4 4k has relatively slow bitrate per pixel but I think that better profile compensates that partly.
GH4 files are more difficult to decompress because of more complex profile.
 
I found also an interesting thing:
When shooting 1080P video in creative video mode it uses video profile 5.0
When shooting in photo mode using red video button is uses video profile 4.2

There are big differences with 4:2:0 cameras chroma quality too.

measures cameras chroma resolution and results (at 30% contrast)  indicates big differences:
 
Canon5D3         250 horizontal lines
Sony NEX7        260 horizontal lines
Nikon D5300      300 horizontal lines
Sony RX10        340 horizontal lines
GH3                   400 horizontal lines  (theorethichal limit would be 1920/4 = 480 lines)
 
Unfortunately they have no Sony A7R test 
 
I think that due to codec limitations many cameras must throw away chroma resolution to maintain some level of IQ with low bitrate and low codec profile.
 
I have GH3 and my eyes say that it has a very good chroma quality for a 4:2:0 camera. Reds are not aliasing so badly like in other cameras.
 
By the way why is it called 4:2:0? That sounds like there is no vertical chroma resolution at all. What I understand it should be called 4:2:1 (proportions of luma res : horizontal chroma res : vertical chroma res ).

Why not buy a good TV for video editing. TVs are made for showing video.

I think that at Chrismas we can hope some things for coming year. GH4 is in horizon. Panasonic guys are reading our posts. GH3 got many features users wanted. So lets not be too modest. Here is my hopelist for coming GH3 successor:
-autoiso in M (there is a high demand in the field)
-autoiso limit for video or iso range
-every menu item programmable to every Fn (maybe not format). I have only 4 items now that I absolutely want for Fn and none of them are possible??
-exposure values programmable to C1,2,3
-when recording video, ALL exposure values must show in automatic modes. Now those are blocked
-more C memory slots
-manual settings for creative mode
-AE/AF lock on-off-on-off etc., during recording
-better EVF resolution and better ocular
-no useless buttons
-4k video 50/60P (pal/ntsc switchable)
-bigger handgrip, better button layout ergonomics
-flat mode in video which uses whole sensor dyn range
-separate video/photo switch. So all modes and handy buttons is in use for video. And then all settings must be independant for video or photo.
-more options for bracketing. -2, 0,+2 steps would be handy for HDR
-playMODE button to right side. Now it is difficult to use because left hand holds objective.
-adjustable AF-range and mayby towards/backwards function if AF-C will not be good enough.
-iso 50 would be handy for video in bright light
-dual memory card slot and option to copy mem card.
-better microphone with wind shield option.
-more WIFI functions and recording options
-stepless aperture change in video
-better (louder) speaker
-more songs to slideshow and simple crossfade option
-if using slower than 1/25s shutter in video camera should go automatically to proper manual mode maybe with warning
-HDR video (dual iso) like ML canon
-faster timelapse (maybe 1/10s interval)
-obviously better and faster sensor. No more rolling shutter in silent mode and 1/100 000s SS.
-120 or more fps with proper resolution
-adjustable autofocus speed in video
-softer and better shaped eyecup
-adjustable tone curve via computer and other modifications like Nikon V1
-electronic stabilator (very handy especially with 4k)
-stepless smart zoom for video like rx10
-video editor with capability to smartrender finished program (smartphones have it)
-stepless adjustment wheel for exposure -rx10 has it (maybe switchable steps/no steps)
-in camera LED light for video
-open source firmware for developing or application store for new features - like sony nex5t
-cinematic look option button: (24P 1/48 ss, with greenish/brownish color cast) :o)
-red led with text VIDEO because every subject is always asking are you taking a photo or shooting video.
-lens cap which you can operate without taking it off camera
-small directional add-on mono microphone which sound you can mix with stereo mike.
