2D animations are usually 12 frames per second. When an artist draws the animation, they need the exact number of frames required. To effectively determine the number of frames, consider creating an animatic. Rest. Elements without motion still need to be brought to life. Create variations of...
However, intentionally reducing to half Hz has other benefits such as improving smoothness in imperfect-framepacing situations (since the coarse refresh cycle intervals produce a better one-dimension snap-to-grid effect for frames-to-refresh-cycles. Higher Hz for lower frame rates can add microstutt...
