The honest advice is:
You can produce nice images in ArchiCAD, considering it's a CAD application (and the LightWorks engine and the new book from Dwight Atkinson should both help), but IMHO to produce really great animations, you'll best export your ArchiCAD model into one of the top animation applications: 3ds max or VIZ, Maya, Lightwave, Cinema4D and similar applications.
You can get reasonable/professional results in cheaper applications too: Carrara, Strata3D, Truespace.
And it sounds expensive, but the gained control over material settings, animation curves and the speed for rendering high-polycounts and one dedicated "operator" (can be a junior in an office) should compensate for that, if you are in an office that needs this imagery to go one step further.
