Tips for creating Animations in ArcGlobe

It is very easy to ask ArcGlove to make an animation file that takes for ever or even longer to render. The art of making animations is not to create the most elaborate animation possible, the real art, once you have experience, is to make an animation that is is simple, that expresses what you want to say and actually renders in a reasonable amount of time! Here are some tips for making animations in ArcMap.

The ArcMap 3D Analyst Extension Manual has very brief explanation of how to make animations in Chapter 8. Somewhat more inspirational is this Article from ArcUser Magazine More in-depth coverage can be found in this supplementary document: Advanced Animation in ArcScene

For some reason, none of these sources tell you the following:

  1. Keep your ArcMap Window SMALL! The size of your animation file and the amount of time it takes to render is proportional to the area of your arcmap window. The Options at the bottom of the Export to Video dialog would let you set the ressolution of your animation independently but it is most straightforward to just adjust your arcglobe window to be as small as you want your animation to be. And keep it as small as possible! Keep in mind that you will be placing these in letter sixes documents, so a 3"x4" animation should be fine.
  2. Also in the the Options panel at the bottom of the Export to Video dialog you will see the option to Enable Off-Screen Recording this will prevent things like your email browser from turning up in your animations should they cross your arcmap window.
  3. Use Quicktime in my experience, the quicktime video capture has more useful options and seems to be quicker. This reqires that you have quicktime installed on your computer see www.quicktime.com.
  4. Make a Trial Run with SIimple Layers and Low Quality YOur first goal; should be to get an animation that renders quickly, then add detail and quality in controlled steps so that you can understand the cost of each individual tweak. So befin by turning off layers like high-resolytion photos or very detailed 3d buildings or 3d symbols) extruded buildings ona simple globe surface would be a good place to start. Then make your window very small, and make a quicktime animation with low quality and a low frame-rate -- like 10 frames per second. Incidentally, the length of your animation is set in the Duration dialog on the Animation Options panel that is part of the animation player in ArcGlobe.
  5. Oddly enough, ArcGlobe seems to get slower each time you run a big animation. For best results, save your arcglobe project, quit and restart before saving a large animation file.
