Sorry to hear you're facing these troubles. Might be, you are using the Camera - Distance Falloff feature?
When rendering a "walk-through" animations, this feature shouldn't be used to prevent any kind of troubles. As mentioned in our on-line reference guide (https://docs.itoosoft.com/forestpack/forest-plugin/camera#Camera-Density/ScaleFalloff):

"Be careful if you use falloffs with camera motion, because items may appear or disappear suddenly (the distance to camera changes when moving)."

Also, I would suggest you switch to the Custom Edit mode to see if there is any difference.

Optionally, you can do a quick test using Forest Tools and export all scattered geometry to instances. You can find it under Utilities - More ... - Forest Tools.
For more information about it, check our on-line reference guide (https://docs.itoosoft.com/forestpack/forest-tools). This way you can check that the problem happens during Forest object conversion or not.

I don't use distance falloff. Now I will check other.

Instantiate function works well, but it not useful, because i have many cameras and different Forest objects.

If You see LODs rebuilding, then it is too big of a difference/they change too close to the camera

I place highpoly trees near the camera (20 m); midpoly (up to 100-200 m) and flat plans for the rest of the distance. I need to do that, just need freeze this condition.

Is it possible to freese LODs rebuilding except Instantiating?

So, now I turned off LODs, but can't turn off Distance Density falloff. Grass instantiating looks like madness. How to freese a Forest?
