I need help! and fast! and today if possible! please help!

Help please, I am doing 3D character animation for school and I need help with speeding up my animation without having to move keyframes. please reply AS SOON AS POSSIBLE, I really need the help.

Turn up the framerate?

You can also use time remapping for the whole animation, in output properties (printer icon) - time remapping
for example old 100 new 50 will give you twice the speed.

ok, how do I find the output properties (i know it is a printer icon but where do i find the icon)

Note this will speed up the animation, it will not change the length, the end frame will remain the same. If you want the animation to be shorter you have to also change the end frame number.
