24hour non stop recording in a single file on a 128Gb SDXC?
I don't have experience with that particular Samsung camcorder, but I did do some long term recording on an older Samsung camcorder. My camcorder had a time lapse mode that allowed it to capture a frame every minute or so. It would record while plugged in to A/C power. Although the camera used the FAT32 filesystem with 2GB file limits, it was able to span the recording across multiple files. As far as I could tell, the process was seamless.
