Problems of resolution with the camera in the matinee

I have problems with the animation of the cameras, the scene or the matinee. The visualization of the game I see everything well but when the animation that creates jump the beginning of the game the resolution of the textures is lost and it is blurred.

Can someone help me please?

Potential problems I see:
It is a package of vegetation with three types of texture resolution, maybe it would be better to leave one?
The light map is very large and I have to get down to resolution?
Is it a camera speed problem?
Do I have to activate a box or make a blueprint?
There is a trick I do not know?
The calculation of light is lost even if I see it in the viewfinder with good resolution.
