I recorded 500 frames at 30fps. I am trying to save as TIFF files to an SD card. I pressed "save" and it got 72 frames in before freezing. I waited to see if it would resolve but after about 10 minutes, no change. I cannot abort save and have tried powering down the camera (how I normally do by pressing the power button for ~1-2 seconds) without success. It is still frozen. Has anyone else had this issue or been able to resolve?
