I've been testing Rig's GOP1 GH1 patch...I bought 3 Sandisk Cards today:

8gb Extreme 30mb SDSDRX3-8192-A21

16gb Extreme 45mb SDSDRX3-016G-A21

8gb Extreme Pro 95mb SDSDXPA-008G-A75

Recording this bush, it would fail instant with EVERY card. I changed the GOP to 3 and it started working, but then failed after 3 seconds or so. I stepped back a foot and it started recording alright though stream parser showed some missing frames in the high detail, but going frame by frame in Vegas, I didn't see missing frames....SIGH....super high detail and low GOP on the GH1 just don't mix....even with the 95mb cards.

I'll test the GH2 this weekend. Also used a purple and pink filter simultaneously and the image is CC back to normal.

@LongJohnSilver Sorry for the late reply, but I have ordered a Sandisk 16GB Class 10 95MB/s SDHC card which is apprantly suppose to handle Sedena Q20 in all modes? Because once again, like my previous 32GB card, it keeps stop reocording in Manual movie mode and especially at ISO128000 :(

Anyone tested this 128Gb 45MBs

@RatLABProductions

I have the card you linked to. Have used it for Sedna Q1 and Canis late day, without problems, except when I've made a few deletions on the card (that appears to lead to aborted recording). I haven't attempted to span with any setting.

One issue which does concern me is occasional motion stutter in playback out of the camera, but since in most cases this occurs randomly (doesn't appear to be baked into the file), I'm assuming it's strictly a playback issue, too much data, in high-data scenes.

Money spent on a 95 MB/s card is never wasted. You get a good, fast card that will perform more reliably than anything else in the GH2, even if your encoder settings don't require the fastest card. With these prices, I see no reason to buy anything else.

95 MB/s 32 GB, certainly. It is what I use.

@RatLABProductions Yes, it seems you are right about 30MB/s cards. I've ordered two from Amazon UK and received two 45MB ones, even though I asked them before if they have 30MB/s cards. I am probably not going 95MB route, since the cards are relatively expensive and I am not planning to use high bit rate patches/hacks. Sending cards back would not solve the problem, since it seems that they run out of 30MB cards.

Are 45MB/s cards really so worse than 30MB/s that I have to send them back? I hope they at least better than Transcend 32MB Class 10 cards?

Hi! I've bought a SD card Sandisk SDXC 64GB 45Mb/s but with my gh-2 with flow motion FW Sometime freeze the machine! I've tried with the original and non original battery and is the same... The curious is tha the machine freeze when i start the rec... i need to remove the battery because i can't do anything (the on-off switch is unusable)

I think that can be the sd card because whit the other sd card (16GB) i have no issue...

Settings used: Flow-motion 2.02, Nostalgic -2,-2, 0, 0, ISO 12800 B&W standard. 24p Cinema mode, FSH.

I have been using the 64GB 45 MB/s card and it hasn't frozen on me in the last few days of using it on my newly acquired GH2. When I try to watch the footage it sometimes breaks up and freezes... I suspect this may be the decoding VLC player is using on Mac?? When I put the footage into Premiere Pro CS6 it can edited and play it fine and smooth.

The camera is not giving me an error message when recording and hasn't crashed yet. Is it normal to play like gunky blocks because of the footages' high bitrate?

I apologize if this is a stupid question, and if the answer is already posted somewhere, please refer me to it (as I tried hard but did not find it yet).

I know I need Sandisk SDHC cards. Many people here suggest at least 30MB/S. Can someone explain how the 30mbs cards would be fast enough for most GH2 patches (@driftwood / Flowmotion ) who write 45MBs, 90 mbs and much more (like 130mbs)?

Thanks so much

I have the sandisk 45mb/sec 32gb card and tests with quantum 9b hack by driftwood were successful. streamparser shows 118 mbit/s

If I put some good movement in the camera or film something like a promo with lights and dancers I can't record with the hack on recommended settings on my old transcends or other supposed class 10 cards or the sandisk extreme supposed 45 mb/s, nothing I have. Seems fine on 24fps but 25fps is crash and burn every time.

@vtablix I can't give you any technical reasons for why, but with my 16gb 95mb/s sandisk card I only got about 20mb/s when using my usb 2.0 ports with 3.0 reader, now with 3.0 ports the speed is up between 70 and 90mb/s, so in my personal experience the card speed tops out around 20 with usb 2.0.
