Very easy program to use. Took me no more than a minute to figure out how to get the right filesize out that i wanted. Did not crash even with several other programs running at the same time. No problem resizing 3gp files to fit on my phone.
next time add mp4
Very easy-to-use for spesific task program. Worked great on my pc running xp home.
