It is a feature request really, but as it will be good to have it in QGIS 3.4 and also the changes are trivial, I file it as a bug :)
Currently, you can view the animations from the 3d but not possible to export it as an avi. In long run, it will be good to have ffmpeg as a part of QGIS package. But meanwhile, we should allow users to export the frames as pngs so that they can create the avi outside QGIS.
