I'm shooting a 1.5 hour performance tomorrow night (just got the gig tonight) and I can't afford to have the any issues with spanning. I've seen posts that 32MB at 1080p/24 is stable but I don't have time to test it out. Can anyone share their experience? I'm tempted to reset the camera to its original firmware to avoid any problems. I've got 32gb Transcend Class 6 cards. Thanks.
