I just finished doing an intro page with an animation, I have now seen that the logo is too large how do I make it smaller without seeing the action on the animation? because I tried but then seeing the preview makes me see all the passages of make it smaller in a animation.
Probably before doing the manipulation with size you need to turn off the Auto-keying? It will not allows to insert keyframes for these changes. Also you can check what manipulations your keyframes have now and delete unnecessary.
