Hi,
I looked at the video and to be honest I don't think it's going to help. Like I said before how are people showing their designs and they look almost like a photograph? They are obviously not using Sweet Home 3D or not the rendering engine that is built it?
I have put links in below. The first one is my image from SH3D and the second is from a competitor of ours and I don't know what package they used for rendering the floor layout but you can see its a lot sharper.
