AnimationVideo fails with same arguments as working Animate

What must I change in the Animate arguments to get AnimationVideo to work?

This seems to work:

AnimationVideo[
 Graphics3D[
  MeshPrimitives[
   DiscretizeRegion@
    RegionIntersection[Sphere[{0, 0, 0}, 2], 
     InfinitePlane[{0, 0, z}, {{1, 0, 0}, {0, 1, 0}}]], 1], 
  ViewPoint -> {2, 2, 2}, 
  PlotRange -> {{-2, 2}, {-2, 2}, {-2, 2}}], {z, -1.95, 1.95, .5}]

I really I knew an easier way to turn a Region into Graphics3D.

That works! Thanks!

PS: I'm not sure what Wolfram uses for a theoretic underpinning for its type system, but it would seem that type -- or at least protocol -- inference may afford a friendlier experience. I know there are differing opinions among language designers on how much automated inference the language should be permitted, but given the original purpose of Mathematica, one would expect it to err on the side of inference.

If you really want to be lazy, Rasterize can convert any expression in the forntend to an Image So AnimationVideo[Rasterize[whaterver]] will always work.

AnimationVideo[
 Rasterize@
  Region[RegionIntersection[Sphere[{0, 0, 0}, 2], 
    InfinitePlane[{0, 0, z}, {{1, 0, 0}, {0, 1, 0}}]], 
   ViewPoint -> {2, 2, 2}, 
   PlotRange -> {{-2, 2}, {-2, 2}, {-2, 2}}], {z, -1.95, 1.95}]

Animation video only takes Head Image or Graphics. Your result outputs Head Region.

RegionPlot3D outputs Head Graphics and therefore works.

Or more cumbersome you could use DiscretizeRegion to extract the mesh primitives and make your own graphics.

I meant, instead of Region.

Doing that substitution at least produces a video but it consists only of a bounding cube. It doesn't contain the animated circle when played.

Try RegionPlot3D
