merge video

I want to know if it’s possible to merge objects into a video (mpeg,…). and to adjust lights…


could u please be more explicit,i don’t understand for what u ask.

i have a film, i want just to add some models into. and adjust lights to be realistic.
it’s possible with blender?

I am no expert on blender,but after doing an animation with blender maybe u may merge them with a video editor frame by frame and add effect or some filters to make it realistic.
