Matching framerate

By default, Blender uses 24FPS framerate. Minecraft uses seconds to define the timestamps of keyframes in animation. It’s good to change the framerate setting into something that divides 1 second period into something nice - for example (25FPS or 20FPS). 1/24 is 0.0416666 but 1/25 is 0.04 which looks neater in the animation file.

You can find the framerate setting in Output Properties -> Frame Rate.
