| - | * There are sporadic reports of a "file number limit exceeded" error message when attempting to record with 64-GB SDXC cards. It looks like the problem is fixed by reformatting the card, and avoided by recording a short clip after spanning and before turning the camera off. | + | * Using 64 GB SDXC cards, sometimes when you begin recording video the camera refuses and displays a "file number limit exceeded" error message. The problem is fixed by reformatting the card, and avoided by recording a short clip after spanning and before turning the camera off. |

| * The above cards have proven to be reliable, consistent from card to card, and fast enough for even the most extreme high bit rate PTool settings. Other cards will work at lower bit rates, but they will hardly be worth your trouble to figure that out. Please just buy one of the above SanDisk cards. Most PTool settings are designed for the above cards.

| - | * The SanDisk Extreme HD video 30 MB/s cards are apparently being discontinued and replaced with "Extreme HD Video" or just "Extreme" 45 MB/s cards. Early indications are that the new 45 MB/s cards perform similarly to the old 30 MB/s cards in the GH2. 45 MB/s Extreme cards are not to be confused with the old 45 MB/s "Extreme Pro" cards, which are not recommended. | ||
| - | * The 95 MB/sec 64 GB SDXC card allows spanning at the highest possible bit rates, whereas the other Extreme cards do not. At somewhat lower bit rates, all of the SanDisk Extreme cards will span. [[http://personal-view.com/talks/discussion/1491/95mbs-sandisk-extreme-pro-spanning-reports-64gig-sdxc|discussion]] | ||
