The same tools than oher app (ffmpeg, mpeg to work), but WITHOUT the price !
No need to search for parameters, the soft is -well- automatised.
One of the greatest of this app is the ability to suspend process (if you want all the CPU for another work during the encoding) WITHOUT loosing the previous encoded data !!!!

I dropped, I clicked and that's all (I have a result AND IT WORKS)

I didn't try the burn option, then I dunno if there is problems (like other reviews said).
if you want to spend money with less good softs... ;)
