Rendering an animation then saving it as a video is black I asked this question a few weeks ago, but I guess I didn't explain it enough. I am a programmer so sorry if this is a stupid question.

I have a scene with a camera that has an animation fully setup. I was told you can go to render animation with that object that has the animation selected to quickly render all frames of that animation, however when I do that all I see is black, besides a few objects in my scenes that have a "glow" material.

I have a light "sun" pointing towards everything else, so it should be rendering the light, but for some reason it is not. The thing that confuses me more is that when I got to the bottom of the 3d editor to select show in "solid", "material", "wireframe", and "rendered" all those, in rendered it shows up fine.

And just to be clear cause people in the previous post seem to think I'm talking about the video being black, I'm not. I'm talking about when I go to "render animation" in the rendered tab it renders the animation frame by frame as black. 

If you need screenshots or even the file let me know and I would be happy to send it.
The box called Sky has a Background shader. This shader is only meant for the world, and it is ignored on anything else. While the box is hidden from the vireport, it is still enabled during render, and it occludes the background light coming from the world. If I give it an Emission shader, I get this.
  

If I disable it altogether, I get this.
  

The sun lamp is a special type of light, that basically only gives a direction and a strength, and act like it is always outside the scene, regardless of where you actually put it, so even if it's located inside the Sky box, the box occludes its light. Take a look at Lamps in the Blender online manual.
