rigidbody meshes won't move! at all I've been doing some camera tracking and its all been working fine. then when i tried to add rigid body it wouldn't move

sorry if I'm not being that specific but when i bake to keyframes only two keyframes show up at the beginning and end btw my beginning frame is 908 and end is 1040
sorry it turns out i had to go into the rigid body cache and change its starting and ending frames
