4K Chat

The GH3 HDMI clean uncompressed signal output is 4:2:0 8bit. I can only guess that for the GH4 4:2:2 8 bit will be for 1080p and 4:2:2 10 bit will be for 4k.

I would guess the opposite, HD being 4:2:2 10bit and 4K being 8bit as this would otherwise really be pricey. But that's just my guess. But if it is 4:2:2 10bit on the 4K side then this would be awesome!

When looking at this video of the JVC JY-HMQ30 (not available in USA) I notice that Youtube now has 4k streaming:

Tend to agree with vader - this would put it in EOS 1DC territory for a fraction of the price (if the rumours are true).

More photos of the GH4k. Although I read somewhere that it is a little bigger than the GH3, it looks from the photos that it is a GH3 turned into a 4k camera. All controls and features are in the same place. I really hope it delivers good 4k videos. I wonder if it has dual card slots.

In less than 60 days we will know the real story.

It looks just like that. A GH3 with a 4K sticker on it.

@stefhoffer - I find it suspicious that they did not have a working prototype at CES 2014 and that there are no sample clips so close to the launch date. You are right about the sticker. I hope they do not have the same bad habits as the people from BMCC.

And Sony

Well, like you say, only time will tell. It is really odd that they are supposed to announce a camera in a few months' time and are unable (or unwilling) to provide any official details at all.

If it's real, the GH4 looks like the perfect travel camera and a good alternative to now more expensive models. Although the file sizes and storage costs continue to be a problem with 4k in general, when working 'on the go'. It seems many people will end up having to invest more money in cards and storage than the actual camera.

My ears are perked, but I'm as yet wary - moot point anyway, since I'm not shopping now, (can't).

But the way I look at it, Stef, you could shoot 1080 for "normal" and choose 4k (and higher bit rate) when you figure a particular scene is worth it.

Anyone know why I might be incorrect?
