Question: How many frames are in one second of animation?
There are 8-frame walk cycles, 10-frame motion studies...but how many frames actually make up one second of animation?
Answer: That actually depends on your method of publication and the quality you want. For standard quality web animation, there are 12 frames per second; high quality web animation downloaded over high bandwidth goes up to 15 frames per second - which is, coincidentally, the default frame rate for standard quality television animation. 24 frames per second can be either high quality TV animation, or low quality cinematic animation, while high quality cinematic animation is generally 30 fps.
So really, there is no universal "default" - but there are several standards.
