@Raysito22 It seems like the camera understands the sdxc cards as FAT32 even though they are exFAT. Most likely there is something more in play than the file system only, but I don't know enough to say what that would be.

Mind, I did a complete erase in disk utility / mac to change my sandisk 16gb into exFAT.

V5 is ok but 720/60p sometimes dons't work about card speed limit , today i want to solve it with V7 , come another problem ...

oops my bad... spanning does work in 24L. i had the mistake of loading the the files individually in clipwrap, i should have dropped the entire avchd folder. :) but another thing, it stops recording after 10 minutes.

@balazer - exFAT doesn't seem to be the reason.. at least not the sole reason. I did a test today, formatting a 16gb 30mb/s sandisk to exFAT - had to reformat it in the camera and after it was read as a FAT32.. I did a spanning test with it aswell and there was no success. (just like jfro's experience).

I did not expect it to work, because then there would have been no need for spanning at all on the 95mb/s cards. (exFAT has no file size limit) Had to try it out, anyway! :)

@sohus, Seaquake has been stable on my 32gb transcend class 10. It spanned on H setting the other night on fireworks ISO 2500, but the average bitrate there was 80 mbit as it was mostly black. But its perfectly stable on mine even in the most complex of scenes with max bitrate.

Tried out new Quantum V7, it's perfectly fine on my card.

Shot some with quantum 7 today.. Spanning did not work in L on a sandisk 16Gb 30mb/s at first, after an in-camera format I tried again (low intensity scene) and then It kept going.. (I didn't let it record the whole card). I wouldn't hold my breath for it to span in a scene that pushes it, though. It seems like it's it's just on the edge of what the card is capable of.

@Raysito22 I'd be interested to know if you take a exFat 64GB Extreme Pro card, stick it in a GH2 if it read/writes to the card. If not and you have to format the card in the GH2, take the card and check and see if it's still exFat or now a Fat32 format.

I just tried formatting an old card into exFat and when I put it into the GH2 it made me format it and then it was back to fat32, so I'm just curious if there's something I don't understand about formatting storage.

@koli, appart from what WhiteRabbit said, I can confirm 32GB 95MB/s will not span, as it's my main card. Though it has no trouble with Driftwood's latest Quantum v7, obviously up to 4 mins. For short films, it's perfect and very reliable to use with actual and future hack patches. It's as reliable as the 64 GB for everthing, but if you look for spanning, look no other than the 64 GB version.

It uses exFat instead of Fat32 which is the main reason for it being capable of spanning. Read on Spanish distributor's page. All other versions still are Fat32.

Hope it helps.

This is an ISO3200 sample of my latest "megaMAQ2".

@Driftwood In my opinion, Quantum V7 is the best Driftwood's patch in 24 H mode. This is that I'm guess, after some tests that I did last weekend in real world.

@driftwood OK, I will do. :-) However, since I think that 24L does not not much have a meaning compared since it is ignored until now with my patches, comparison of 24H becomes main.

@driftwood Here are some results of my testing with SeaQuake and Quantum V7. I had reported in earlier tests using Seaquake that I was able to span both with 24H at 160/166 mb/s and 24L which I had changed to 100mbs successfully on a Transcend 64GB SDXC class 10 card but span failed on Sandisk 32GB Extreme HD 30mb/s. During this test Seaquake was at AQ3. later I changed Seaquake to AQ4 and did some additional test on Saturday. Spanning failed on both cards. Important to note that I never experienced the "CANNOT RECORD. FILE NUMBER EXCEED LIMIT" error. Yesterday, I loaded Quantum 7 and did some testing. Spanning failed on both cards. QV7 is at AQ4. I also experienced the file number exceed limit message above for the first time on my 64GB SDXC card but not the sandisk 32GB extreme. Then I came home and I changed the AQ of QV7 from 4 to 3. I did some additional testing by setting the camera on a tripod and zooming on the 55" TV screen. This time 24H at 147mb/s spanned but stopped after 2 spans on my 64GB SDXC card. However, the file number exceed error message happened again. So just to isolate whether this is Quantum related problem or not, I reloaded the SeaQuake AQ3 patch and formatted my Transcend 64GB SDXC card. After further testing, both 24H and 24L spanned 5 times with no problem before I stopped them. By the way, the file number exceed limit error above did NOT happen again. It appears to me that the file number exceed error only occurs with 64GB SDXC file formats. Note: I only use driftwood GOP1 Intra patches for 24p. I use longer GOPs for 1080i and 720p60. I hope this helps.

@bkmcwd Hmmm... that's an interesting result. Can you upload a few GOP3 tests for H and L setting using the Quantum settings and two of your current own settings? Thanks mate
