QUESTION
Why does rendering sometimes take very long?

ANSWER
Rendering times will increase if your scene is 'too complex' and your hardware isn't powerful enough and/or lacks free memory. 'Too complex' refers to the following variables:
  • A) The number of different models you've added to the scene.
  • B) The 3D Points number (displayed in the top right corner of Build mode).
  • C) The number and resolution of textures/materials.
  • D) The Movie/Photo effects you're using.
  • E) How many reflection planes you've added in the Reflection effect.
  • F) How many Spotlights that are set to Shadows -> Accuracy in the scene.
  • G) How many Spotlights you've selected in the Global Illumination effect.
To reduce the time it takes to render an image of a clip, you should try to reduce the number of all of the above.

In particular B, E, F and G.
