For video cutting TMPGenc has two types:
1. Tmpgenc free : *www.tmpgenc.net/
2. Tmpgenc express: *tmpgenc.pegasys-inc.com/en/download/te4xp.html

great software. Very easy in use also in comparison of Ulead Video studio

U mean to say:- remove some part of the video then try Xillsoft Video Convertor

Google for download... I am too lazy to search.*s269.photobucket.com/albums/jj44/visio159/Unismilies/52.png
