I'm completely new to digital video and suspect that I'm missing something blindingly obvious, but...
I'm trying to convert AVCHD (MTS format) files into a more generally accessible format (MPG, MP4, etc.)
I'm using the freeware Oxelon Media Converter v1.1 to carry out the conversion. The first couple of attempts resulted in a successful conversion. However, all subsequent conversion attemps have resulted in an MPG or MP4 file which is twice the duration of the original file. The audio stream sounds fine but ends exactly half way through the video, while the video stream appears to be playing in slow motion. I'm guessing this has something to do with frame rate, but I get the same result no matter what settings I use for conversion.
I'd be grateful for any help that anyone can offer.
Thanks in advance.
