had anyone tried kdenlive on a atom pc? maybe a netbook or a 945GCLF based motherboard, I think this has ss3 so how can we expect to run video editing? will this work?

I used to edit with premiere 4.2 in the 90´s on a pentium PC, so I imagine KDENLIVE can take 720x576/25fps editing on a tiny pc doesn´t it?

Set your window size to ATOM PC size and test Kdenlive. We don't know wether this will work.
