hope all the artifacts are not coming from the camera!

i think youre looking at green feathers on top of other green feathers at a different angle, maybe a touch of aliasing paranoia?!

[etidona]

Maybe my eyes are used to see good codecs;)

Ignore! That screen shot is compressed and over sharpened to hell - just look at the 4K motive, icon (not from the camera) in the top right.

[J.P]

according to the pdf presentation it does 40fps with electronic shutter.

Could this do some V1 style shooting? :)

I just saw it's compatible with the GH3 battery grip

 

 

good stuff :D 

 

That also means it will be compatible with GH3 batteries. No need to replace accessories.

This is late and I hope you are still reading this thread...

 

It sounds like you have Panasonic's ear, so I was hoping you could pass along the following (if you think it is a good idea...). Given that a crop is used for the video modes, what I would really like to see is an "expanded" 4K or Ultra-HD mode, where it records a wider image with a band of extra pixels around the outside of the usual crop. That way you could do stabilization in post without having to upscale and lose IQ. You would lose a little on having to compress a larger image, but you would gain I think in both the simplicity and the quality of the stabilization, because you would just be moving around the 4K/UltraHD window.

 

Thanks for all you do!

Do you need the eternal add on to go out to a ninja for 4:2:2?

I wish for a battery base with just audio interface and 2 XLR adapters, something like the Tascam DR-60 but  less bulky. I'm sure i will use the 4K just for re-composition, and the upgraded HD image and another specs will be my main reason to get the GH4.

Only if you want 4K 4:2:2. HDMI on the GH2 does 4:2:2 in 10bit for 1080p to the Ninja.

This is exactly what I suggested to Panasonic in our meeting :) "Super 4K'. A near 5K camera in a sea of 4K cameras this year, would be good for sales as well as for us.

I was calculating a 2.61 crop factor in UHD mode, until I realized that you can't compare a crop factor from a 3:2 stills format directly with 16:9 video format.  My calculation is now 2.49 based on using the full sensor width of a full frame sensor.  Still a hefty crop factor, but I can understand the engineers not wanting to resort to pixel binning, which would create artifacts.  I'm sure they wanted the sharpest picture possible.

Andrew,

 

I am dying to know if the GH4 eliminates the 10 Seconds “Screen Off†issue that has plagued the GH3. Does or will the screen display elements (i.e. audio meters, level gauge, battery, card, etc.) of the GH4's LCD stay active/on indefinitely while recording video????

 

Great article!!

The GH2 does 4:2:2 in 10 bit 1080p to the Ninja? Or do you mean the GH4?
