Really; I like your technique;
- The animated objects bring life to the video
- Using movable lights is time saving & headache relief :)… :
…There would be no need for Unwrapping objects for UV2 (for a lightmap)
…There would be no need for Building lightmaps (which may take many hours; especially in a scene with hi-poly meshes)
About the lighting system…
When I use a Directional light, I got hard shadow edges…
while in your video what I see was only Ambient Occlusion shadows (I think so) !! may be the directional light is set to movable as well, OR something I’m missing…
What about Render settings? did you use a PostProcessVolume OR a LightmassImportanceVolume …?
The music was a very good choice… Every thing was just like a celebration…
Thanks for sharing
& Best wishes
