Video Editors and 3d

I'm fairly new to the site, but i've not anything in terms of 3d or non-linear editors. So what do you guys think?

Great 3d software, pretty much portable after the install.

Yafray is partly integrated into Blender as a plugin, and is semi-portable. Either way it would be nice to have a portable renderer available no matter which one it was.

This is an up and coming video editor, but it has promise.

Good video editor. Not sure if it’s portable though.
