Hey I have this camera in my hand and the SanDisk Extreme 32GB (45MB/s) combo works well so far when shooting 4K video @ 100mbit. I'll try some more tests later today with different cards.

+1 Although I was thinking about ordering from the US as they don't have any time recording limit...

Thats sounds like great news for people who didnt even have the 80 or 95mb/s.
This I pretty much figured, if you have time to please test the 1080p 200mbit I would be verry greatful since its the one I hear both yes and no about
Isnt it just like the GH3 that didnt have a limit but made separate clips of it? I wouldnt go US anyway because of the framerate, every ntsc camera I have had caused me trouble at some point.

The GH4 is a world camera with switchable frequency.

Ok then, didn't know that
Still I will wait so I get the 2-3 year warranty (depending on how much you are willing to argue) and the candy that my regular retailer always include.
The recording limit doesn't affect me even if it didn't start a new clip automatically at 30min since I have only shoot a clip that long once in the last 10 years.

I'm using an even worse card - 64gb Sandisk 30MB/s. Seems fine at 4K. At 200mbps HD, the disk icon seems to flash in an unhappy manner after about a minute.
My guess would be that the 45MB/s cards would be fine for 200mbps HD. I haven't really tested that 200mbps mode that much since the 4K mode is just awesome.
Sorry for the lack of scientific testing! Am at work currently.

This is very good to know!
I just recorded a sunset using 1080 60p 200Mbps All-I with a 128GB SanDisk Extreme SDXC 45MB/s card. Got over 40 minutes recorded, spanned across five clips. Here's the size - time - bitrate breakdown of the clips.
4.233GB - 10:09 - 55.6Mbps
4.237GB - 8:43 - 64.8Mbps
4.236GB - 9:51 - 57.3Mbps
4.234GB - 8:32 - 66.2Mbps
4.215GB - 5:53 - 95.5Mbps
Obviously this slow sunset didn't stress the codec's bitrate, so it's a poor test of the card. I'm sorry I can't be of more help. I'll run more tests tomorrow at our local farmers market. There's usually some jugglers there. Should make for a more complex shot that may better test the limits of this card.
FWIW, I was using the Lumix 100-300mm with F8 and shutter 1/8000th (no ND on lens). Picture profile was CINE-D with contrast, sharpness, color, and denoiser all turned down to -4. The Highlight/Shadow control was set to Low Contrast. Luminance Levels were 0 - 255. I love that the GH4's shutter goes to 1/8000th. My GH3 can only go up to 1/4000th. I'm looking forward to taking stills with this camera.

Those of you being the guinea pigs for testing cards, thank you.

Thank you all for the $150 that I now can do something fun with instead of buying new cards

Was it 60fps slowed down to 30?

Oh, I didn't know that the GH3 worked in this way. That's great as I doubt that GH4 would work in a different way...

That's interesting that the 200mbit all I mode would have a variable bitrate.
If this is the case then that is where you all have to be careful with the slower cards. They may work fine most of the time but as soon as you get a complex scene with lots of random motion and detail the slower cards may not be able to keep up. Instead of locking down the camera and shooting it would be good to really stress the codec with a slower card and see if it can keep up. Like shoot some trees on a windy day or a stream of running water.

Yeah, I have some concern about the idea that the card could drop out on really highly detailed scenes. That said, it looks like this sample of the card can easily do 50MB/s write speed, which is equivalent to about 400Mb/s. As long as it can sustain those write levels when full, I'm not sure that 200Mbp/s max recording bit rate should offer much of a challenge. I should say I did some screen/grass and some persian carpet shots, and I got the 24 FPS all I up to 85Mb/s. I'll keep trying, but so far I haven't maxed out the codec, or the card.
