how can i change increase/decrease speed of animation
thank you very much for your support request.
Select all keys in the Dopesheet window (CTRL + A when the window has focus), then use the blue bars that appear next to your last keys to scale the whole animation. Moving the bar to the left will increase the animation speed, moving the bar to the right will decrease the animation speed.
Please let me know if you have any follow-up questions.
