Worked once, then limted time to 16 minutes

I did a 1 hour video without too much problem, then after that it stopped working and no matter how long my video was it only saw 16 minutes of it, so its totally useless now. I found nothng saying free version is limited in this way so Im certainly not upgrading to $20 paid version to see if that works better.
