As you are using LDCad you could try its povray export.
You would have to script the wanted camera movement using lua though.
POV-Ray should be able to render the movie (could take days) given there is enough memory (using a swap file if you run out, but will that will be much slower).
Awhile back I made an example of a walk trough script here:

Alternative is to use the direct OpenGL export, which will render at only a few times the normal running time (depends on your fps value).
