It's slow. It's unstable. It's ugly. It's uncomfortable, unintuitive, and ... it's Open Source! So, for all out there don't want to pay thousands of dollars for Photoshop it's an alternative. But don't wonder if you become a bald head because of ripping out all your hair when it's crashing again, need so much time to render previews or to start or need 10 steps where Photoshop just need 1 or 2 steps.
It's the best open source converter out there, in my opinion, since MediaCoder violetes the GPL and is not open source anymore. It offers a lot of possible convertions and in opposite to other converters like Format Factory it's no ad- and spyware (?), it don't installs toolbars.
It is awesome........
