I hope this post will help people and save hours of frustration
I used to have problems with Muvee Reveal using video files from my panasonic Lumix ZS3 (AVCHD lite).
Simply convert your video files (in AVCHD format) to the windows media video in a avi container.
I use MediaCoder to convert the video files from the .mts files (AVCHD lite) to .avi (in windows media video coded) using the .avi container.
You can get the free software from: http://www.mediacoderhq.com/
I attached the preset file for your convenience. (It is an .xml file stored in a zip file)
Enjoy the easy of use of Muvee Reveal.
