Here is a some PoserPython and Poser-specific code for MP4s which may be useful...
# MOVIE STUFF. First we initialize the movie.
moviemaker = scene.MovieMaker()
# Set movie output format to PREVIEW.
moviemaker.SetMovieRenderer(poser.kRenderEngineCodePREVIEW)
# Set movie frame-rate of 15 FPS, plus an increment of one frame (i.e. render all frames)
moviemaker.SetFrameOptions(15, 1)
# Remove jaggies, make it nice and smooth.
moviemaker.SetAntialias(1)
# For Poser 11, code 2 = make a MP4 movie with standard codec.
moviemaker.SetMovieFormat(2)
# Give our rendered movie a path and name.
moviemaker.MakeMovie(r"C:\folder\movie_file.mp4")
