A bit of a daft question, and not too sure where to ask it. I have the Sony time-lapse app on my RX1003. I also have it on my A7 and NEX-7 I set it all up, it does its thing for a while, and then at the end there's nothing. I don't seem to end up with a video file, even though I've set it for 24p. I've tried umpteen times and always end up with nothing. Any ideas what I'm doing wrong?
