Seems my order of images are wrong. Last image is viewport and first is render output. Might be hard to tell a difference anyway;) due to the fact I had to reduce the resolution by some amount because of the upload file size limit of the forum.
It could partly be the .avi format and render resolution of 1280 x 720. Try mpeg4 or a different format. AVI requires certain codecs to be installed on the computer, and it utilizes some of the older codecs.
