First you should check if your model has no 3D faces in excess, can have an object with many faces on a scale that you will not see.
According to try opening another file in Lumion little and then return your file to clear the video memory or restart the machine.
Third, in some tests I did when I removed the SSAO effect the problem was solved.
Fourth, you can try rendering the video image sequence, not mp4.
