I agree that most class 10 cards will work. But not for recording 4K.

This according to Panasonic

I am having some display issues with my GH4, my Zacuto EVF + an old and cheap Lilliput 668GL http://bit.ly/1k2hFiL

The Zacuto EVF gives me "Unsupported video format 1080p60-YUV422" on ALL 4K and HD 30/60p settings. 24p HD and 4K shows up fine. On the Lilliput, it's the opposite; 30/60p work on it, but not 24p.

Maybe there is something I'm missing on the camera to get it to send the EVF a 30/60p signal it likes...? If not, then it looks like I'm going to have to spring for new gear.

Suggestions for fixes or upgrades?

Oh well, my Amex monthly closing date is the 27th so I will have an extra month to pay for my GH4 from B&H.

@khill: Micro HDMI cables are not really difficult to find - your only unusual wish is that for the 90° angle - maybe this adapter would fit your needs.

Ah, and by the way: Panasonic does sell Micro HDMI cables - but ridiculously overpriced.

I been watching this thread and I have to admit I am excited. Had planned on selling my GH3 as I was never really "wowed" by it's video performance. Just needed a little more cash for the GH4 - had a guy ask about it and buy it today! Placed my order for a GH4. The posts look promising. I've never bought a camera upon it's release without waiting for the consumer masses to find everything that should've been addressed before the release. From what I've read here am I correct in assuming all the GH4 video modes work with the 64GB 95Mbs card? Or do I absolutely need to bite the bullet and get the $245 SanDisk - PRO SDXC UHS-II Memory Card???

Thanks in advance.

@SuperSet Hey, thanks for the reply. How bout the All-Intra 200Mbs mode? (fingers crossed) I have 3 of the 64GB 95Mbs cards from when I hacked my GH2 and I'm hoping that's all I'll need for any of the GH4's video modes.

Thank you again.

@maddog15 I just tried the 200Mbs mode and it worked fine until around 90s or so. I didn't get an error but the red SD card indicator started blinking on the screen. I don't know if that means if it was dropping frames or what not since the footage looked fine to my eyes later on.

I use these HDMI cables for my workstation, appleTV, etc , have a micro one I use for my field monitor as well.

@maddog The manuals are now up on Panasonic HomePage Here is The link I used http://panasonic.eu/Downloads/sv_SE/popup.html

I overheard, orders for GH4 are apparently 5 for every 1 they can currently make - they can't make enough of them! So get your order in quick or you could be waiting.

Looking at our orders for now it seems so, but we still have few thanks to big first batch.

Plus it is GH camera, they always had such karma.

I think availability will be fine. Panasonic has a good track record as far as Production. They ain't Blackmagic.
