More and more people have their own Camcorder to record their life, family parties and something important to them.
But there are some problems when you:
1. When you want to edit them in Windows Movie Maker or some other edit software
2. When you want to put them into your portable media players, such as iPod, iPhone, Zune, Creative Zen and so on
3. When you want to watch them on some HD video players, such as Xbox, PS3, Apple TV and so on.
4. When you want to share your videos with your friends on youtube, myspace and other online video website.
All the problems' reason is the video format, MTS.
The video format of your HD Camcorder is MTS, and it is not supported by almost any video editing software, PMP, HD video Player and youtube.
So you have to convert it to common video formats.
