Hm, I don't have that software available..
I did manage to create a proxy using AeFx, it took quite a while (11 mins) but it might be a solution. It takes about 2 minutes with SG. (For a green one)
There are more differences between them though. The right one is the one I made using AeFx, left is SG.
First is the size, the one from AeFx is a much larger file while it has the same dimensions. I'm guessing this is because of the codec? In AeFx I can't find where I can select the format to change it to ProRes instead of Animation.
I will do some more testing the coming days, off to bed for now.
Thanks again for the thoughts and help.
