Animation one extra frame?,animation frame

Excuse me, why is my animation one extra frame?
There will be one more frame until the end of the last key frame
Can it be fixed?

it will need the extra 0:01 duration to read the frame, or else it will skip directly to 0:00 if you loop the animation.

You can fix it by dragging the animation duration to the left.

In 2022 it looks like the extra frame has been removed, which I would find convenient but I’m fearing that it would affect all existing animations. Check updates on this thread: https://forum.unity.com/threads/animation-last-keyframe-does-not-add-extra-frame-anymore.1325568/
