Using the Frame Skip option that is under the Vertex Animation Tools section of the script will allow you to skip certain frames.
This is a very useful option as it allows you to reduce the final Texture size while still maintaining the look and feel of the original animation.
If we take a look at the example video below, we can see the Frame Skip feature in action.
The first Teapot you see in front of the word, Original, shows how the Teapot will animate using the full frame range.
The next Teapot, with the number 2 in front of it, shows how the teapot animates skipping every 2nd frame and so on.
As you can see the last example, the effect will still maintain its look and feel even if you skip 10 frames.
