Animations with more than 24 frames can only be created with CLIP STUDIO PAINT EX.

In CLIP STUDIO PAINT PRO/DEBUT, animations with more than 24 frames (3 seconds for 8 frame/sec animation) cannot be created.

*If you open an animation file (.clip) that is longer than 24 frames in PRO or DEBUT, it will be a read-only file that cannot be edited.
