Hi Jose Morte,
The Animation Gauss is by default a little bit more smooth, to avoid temporal anti-alias problems.
Your question: I guess you refer here to the render filter setting Still and Cubic.
Please have a look here:

The Cubic function has a negative amount in it. This might be nice for a still image, but too sharp in most cases with animation/footage. Sharpened footage has an aesthetic which is not very often wanted, if at all. It also works against motion blur and leaves problems for color correction, etc. From where I look at it, any sharpening before “post” is a disadvantage. The problems shown in this quick tip would certainly amplified with any of the options with a negative curve part, said here based on experience, not that I had this scene here to explore it. If quality and post production comes into play, Gauss or Pal/NTSC should be preferred.
All the best
