I have quite a few zero second videos on my Spark. I'm not sure if it's a case of powering down without actually hitting stop on the recording first, so the file isn't closing properly? That's my assumption at this point. Anyone else experiencing this?

Have you tried to format the SD card? If it is possible, please try other SD cards, see if there is any difference.

Hi Diana; I did reformat the card when I first installed it. I don't have another card but I think it has to do with powering down without hitting stop first. I'll try to reproduce it.
