Anyone knows a free video converter?

[Black Dragon]

I'm trying to make some new animated GIFs, but before I do that I need to use a video converter. I use Total Video converter, but there's always some text on the upper left corner of the movie when I convert it. I still need to edit the frames :s

Does anyone know where I can dl another vid converter?

EDIT: BTW, I'm not using it for "evil" purposes, I swear!
