LumenRT Camera Script

I have created a model in ConceptStation, exported to OpenRoads designer and used the script camera path to create a fly over of a project. 

The preview in OpenRoads looks great. When I export to LumenRT it drops a keyframe every two seconds. Instead of flying through the project at a consistant slows down as it approaches each keyframe and speeds up as it leaves that key. 

Is there anyway to get the path to stay a consistent speed through the project?
