help !!!!!! with synfig

hi, sorry about the last topic je je je … well, i am a newbbie with synfig and i get 6 keyframes about a eagle animation, but it see weird, speed is too slow, but is not slowmotion, i tried already with properties keyframes and the animation becomes a disaster.
i need to fix the speed about first 2 keyframes( fast motion) an the other 3 keyframes in slowmotion , but i cannot configure that, all the animation is a same speed, but try to set fast and slow motion in different time around the animation is confuse to me.
PD. I AM BEGINNER AND SORRY ABOUT MY ENGLISH.

please see the other post for slowmotion thing.
