for a friend, who wants to build an outdoor steel staircase, I did a quick rainy afternoon exercise and constructed this stairway using (of course!) SketchUp - so far nothing special at all
Besides various renderings and elevation drawings, I also rendered a video (YouTube link below) which uses the options of simple crossfading. The shown effects play with Enscapes native render styles on the one hand and on the other hand with the on and off switching of SketchUp´s visible layers.
The principle is very simple - in this case I rendered the same animation path 3 times and faded back and forth in the desired form between these 3 versions.
Besides many other things, this option can only be done with a video editor and not within Enscape´s video tool alone...
(SketchUp 2017 Make / Enscape 2.6.0... / MAGIX Video deluxe Premium 16.0.4)
Cant wait till I pluck up the courage to attempt animation 
... I would also never ever do something like this, if Enscape would not be able to render such a video in under 5 minutes
